One German Shepherd Breed, Five Commonly Discussed Lines

Search for the different types of German Shepherd breeds and five names commonly appear:

1. American show line
2. West German show line
3. West German working line
4. East German or DDR working line
5. Czech working line

This five-line framework is commonly used by breeder sources, but it is informal rather than an official breed classification (overview of the five commonly discussed lines).

These are not five separate breeds. They are broad breeding lines or traditions within the German Shepherd Dog breed. The labels can provide context about ancestry and breeding priorities, but they cannot guarantee how an individual dog will look, behave, learn, work, or fit into a household.

The most useful first distinction is between show-oriented lines, where conformation is a central selection goal, and working-oriented lines, where functional performance receives greater emphasis. For prospective owners, however, documented ancestry, verifiable health screening, adult temperament, breeder practices, and the qualities of the individual dog matter more than the label alone.

First, These Are Lines Within One Breed

The German Shepherd Dog is one breed. American show, West German show, West German working, DDR, and Czech are informal names for breeding populations or traditions within it.

Four terms help keep the categories clear:

• Breed: A recognized population of dogs with an established identity and breed standard. German Shepherd Dog is the breed.
• Breeding line: A group of related dogs developed through particular selection goals, bloodlines, kennels, regions, or working traditions. A line exists within a breed.
• Coat variety: A difference in coat length or type within the breed, such as short or long coat.
• Color: The pigmentation and pattern of the coat, such as black, sable, bi-color, or black and tan. Color is not a bloodline.

The familiar five-line system is a practical summary, not an exhaustive taxonomy. A Mittelwest breeder guide, for example, uses six categories by adding an “American pet line” (the breeder’s six-category account).

Wildhaus Kennels instead organizes North American German Shepherds into three broad groups: American show, German show, and European working lines (the three-group classification). These differences show why line names should be treated as descriptive shorthand rather than official divisions.

“American pet line” is especially loose. It may refer to dogs descended largely from North American show stock but bred primarily as companions, or more generally to pet-bred dogs without a consistent conformation or performance program. Because sources use the term differently, it is not helpful to present it as a standardized sixth line.

A simple taxonomy looks like this:

German Shepherd Dog
│
├── Broad breeding priorities
│   ├── Show-oriented
│   │   ├── American show line
│   │   └── West German show line
│   │
│   └── Working-oriented
│       ├── West German working line
│       ├── East German / DDR working line
│       └── Czech working line

│   └── Long
│
└── Coat color and pattern
    ├── Black
    ├── Sable
    ├── Bi-color
    ├── Saddle-pattern combinations
    └── Other colors

These branches describe different things. A German Shepherd can be long-haired, sable, and from a West German show pedigree. Another can be short-haired, black, and descended from several working traditions. Coat and color do not determine line.

The shared breed history came before these modern subdivisions. The German Shepherd was developed in Germany from traditional herding dogs in the late nineteenth century, with Max von Stephanitz closely associated with its standardization. Although initially developed for herding, the breed later took on police, military, assistance, tracking, search-and-rescue, sport, and companion roles.

Different jobs, regional preferences, show systems, and breeding programs helped produce the traditions now described by line labels. They did not create five independent breeds.

Working Lines and Show Lines: The Main Divide

The practical difference between a working-line and show-line German Shepherd is what a breeding program primarily evaluates and preserves over generations.

A show-oriented program places substantial emphasis on conformation: structure, movement, proportions, coat, size, presentation, and adherence to the standard used in its show system. Temperament and useful ability may still matter, but success in conformation is a central selection goal.

A working-oriented program gives greater weight to functional performance and qualities needed for demanding activity. Depending on the program, those qualities may include trainability, endurance, concentration, confidence, environmental recovery, physical functionality, tracking, obedience, herding, detection, or task-specific motivation.

Commercial working-dog sources generally describe working lines as more athletic, driven, and demanding, while describing show lines as more focused on appearance and movement. These are broad tendencies from interested industry sources, not independent findings about every dog (working-versus-show overview).

A working-line German Shepherd may need more than casual walks and occasional play. Some require sustained training, problem-solving tasks, carefully managed physical outlets, and an owner who can teach both engagement and calm behavior.

A working pedigree does not automatically make a dog suitable for police service, protection work, search work, or competition. Those roles require an appropriate individual dog, relevant health and behavior evaluation, specialized training, and competent handling.

Show-line German Shepherds are commonly selected with greater attention to outline, angulation, gait, color, and presentation. Some breeder sources characterize them as lower in intensity than working lines, but lower intensity does not mean low energy. A show-line dog may still require substantial exercise, training, supervision, and mental engagement.

Show dogs can also participate in obedience, tracking, scent work, herding, agility, service tasks, and protection sports. Some earn both conformation and performance titles. “Work” is not limited to bite work, and a conformation pedigree does not erase every individual dog’s capacity to perform useful tasks.

One activity frequently associated with working pedigrees is IGP, formerly called Schutzhund or IPO. It has three components: tracking, obedience, and protection. It is one structured working sport, not the only meaningful activity available to a German Shepherd (explanation of IGP and other working activities).

Question	Show-oriented lines	Working-oriented lines
Primary emphasis	Conformation, movement, structure, proportions, coat, and presentation	Functional performance, trainability, endurance, drive, stability, and task-suited structure
Reported structural tendency	Often described as having more show-specific angulation and outline	Often described as athletic, functional, and comparatively moderate in angulation
Common activities	Conformation, obedience, herding, scent work, agility, companionship, and other sports	IGP, tracking, detection, search work, patrol roles, obedience, herding, and other sports
Likely owner demands	Regular exercise and training remain necessary; intensity varies	May require more sustained structure, mental work, physical outlets, and experienced handling
What the label cannot establish	Whether the dog will be calm, healthy, easy, or suitable for a novice	Whether the dog has the health, temperament, recovery, or drives required for a particular job

This distinction is useful when asking why a litter was produced. It becomes misleading when converted into absolutes such as “working dogs are aggressive” or “show dogs cannot work.”

American and West German Show Lines

American and West German show lines are both conformation-oriented, but they developed under different show cultures and breeding traditions. The available evidence supports describing those broad differences; it does not support declaring one line more authentic, healthy, trainable, or family-friendly.

American show line

The American show line is a North American conformation category. Some breeder sources use it broadly enough to include Canadian show lines.

Dogs in this tradition are evaluated for structure, movement, angulation, color, size, and overall appearance. Breeder-authored descriptions commonly associate the line with:

• A relatively tall or long outline
• A finer build
• A narrower body or head
• Pronounced rear angulation
• Movement favored in North American conformation competition
• A broad range of colors

These are reported population-level tendencies, not diagnostic features. A tall frame, narrow head, sloping topline, or strongly angulated rear does not prove American show ancestry.

Nor does American show ancestry establish how carefully a particular dog was bred. Dogs can descend from show stock without being produced under a consistent program of conformation evaluation, temperament selection, performance assessment, or health screening.

West German show line

The West German show line may also be called a German show line, high line, or Sieger line in breeder discussions. It is likewise conformation-focused, but breeder accounts commonly describe it as retaining some performance expectations alongside show-ring goals.

Reported visual tendencies include:

• A substantial build
• A show-oriented outline
• Pronounced hindquarter angulation
• Black-and-red or black-and-tan saddle-pattern coats

These descriptions overlap with traits found elsewhere in the breed. Color and structure can suggest resemblance to a tradition, but they cannot establish pedigree.

The strongest conclusion supported by the available material is that American and West German show lines belong to different conformation cultures and have been selected according to different preferences. Detailed comparisons largely come from breeders with their own programs and opinions, so they should be read as informed but commercially interested accounts (breeder comparison of American and German show lines).

What this means for an owner

Choosing a show line does not ensure an easy family dog. Ask instead:

• What temperaments does the breeder deliberately select?
• How do the parents behave away from training and the show ring?
• Can they settle during an ordinary day at home?
• How active are mature dogs from previous litters?
• How do the parents respond to unfamiliar people and environments?
• What difficulties have appeared in previous offspring?
• Why does the breeder think this particular puppy suits this household?

Treat the answers as useful observations, not validated predictions.

West German, DDR, and Czech Working Lines

The three major working-line labels reflect different historical programs and regional traditions. Modern pedigrees may combine them, so they should not be imagined as completely isolated populations.

Most detailed descriptions of their builds and drives come from breeders, former breeders, and working-dog sellers. The profiles below therefore summarize reported associations rather than independent comparative findings.

West German working line

West German working lines are commonly associated with selection for working ability, trainability, functional structure, and performance in activities such as IGP. Dogs from these pedigrees may also participate in tracking, detection, search and rescue, obedience, police work, and other sports.

Frequently reported tendencies include:

• An athletic or functional build
• Comparatively moderate rear angulation
• Substantial motivation to work
• Engagement with a handler
• Trainability
• Endurance for sustained activity
• Sable, black-and-tan, or other working-line colors

A West German working pedigree may interest someone pursuing intensive sport or professional work, but it indicates ancestry and potential—not proven suitability.

East German or DDR working line

“DDR” refers to the former German Democratic Republic, or East Germany. The label is historically associated with government-directed breeding after World War II and dogs used for border patrol, military work, tracking, endurance, and related functions.

Breeder and working-dog accounts frequently associate DDR dogs with:

• Strong bone and a substantial frame
• Broad heads
• Dark pigmentation
• Dark sable or black coats
• Focus and endurance
• Serious or reserved working temperaments

These are historical and line-level associations. They should not be treated as guaranteed characteristics of every modern dog advertised as DDR.

The label also does not establish “military-grade” temperament, exceptional health, protection ability, or universal stability. Modern breeders make their own selections, and a dog may have DDR ancestry mixed with other working lines.

Czech working line

Czech working lines are historically connected with Czechoslovak border-patrol and military breeding programs, including selection for working aptitude. Commercial descriptions often emphasize athleticism, agility, tracking, prey or defense drives, and protection work.

Commonly reported tendencies include:

• An athletic, powerful build
• Dark sable coats or dark pigmentation
• Persistent interest in tracking or searching
• Strong prey motivation
• Agility and physical intensity
• Potential for demanding sport or working evaluation

These descriptions do not establish superior scenting ability or make every Czech-line dog suitable for protection work. Some breeder accounts also describe Czech breeding as incorporating East German dogs, while modern pedigrees may combine Czech, DDR, and West German working ancestry (breeder account of working-line histories and overlap).

Line	Historical association	Reported breeding emphasis	Reported build	Reported drive	Associated activities	Main caution
West German working	Postwar West German working and sport programs	Trainability, functional performance, working motivation, sport evaluation	Athletic, functional, often moderately angulated	Work motivation and handler engagement	IGP, tracking, detection, police or search work, obedience	Pedigree indicates potential, not suitability for a specific task
East German / DDR	Government-directed East German programs after World War II	Border, military, endurance, tracking, and related work	Often described as heavily boned, substantial, and darkly pigmented	Often characterized as focused and serious	Historical border and military work; modern sport and tracking roles	Modern ancestry may be mixed, and appearance does not prove lineage
Czech working	Czechoslovak border-patrol and military programs	Working aptitude, agility, tracking, prey or defense drives	Often described as athletic, powerful, and darkly pigmented	Often characterized as intense and persistent	Tracking, obedience, agility, IGP, and protection sport	Do not assume superior scenting, guaranteed protection ability, or family suitability

There is not enough evidence here to estimate the present-day prevalence of “pure” DDR or Czech pedigrees. Claims of rarity or historical purity should rest on documented ancestry rather than promotional language.

Coat Length and Color Are Not Bloodlines

A long-haired German Shepherd is not a separate breed. Neither is a black, sable, white, blue, bi-color, or black-and-tan German Shepherd.

Coat length, color, and ancestry answer different questions:

• Coat length: What kind of coat does the dog have?
• Color: What pigmentation and pattern does the coat display?
• Line: What breeding population, program, or ancestry does the dog come from?

A long-haired sable dog might have show ancestry, working ancestry, blended ancestry, or no documented pedigree.

The Royal Kennel Club lists short and long coats within the German Shepherd Dog breed. It accepts colors including bi-color, black, black and gold, black and tan, dark sable, gold sable, grey, grey sable, and sable. It classifies white, blue, liver, Isabella, and several related combinations as non-breed-standard colors (Royal Kennel Club German Shepherd profile).

That is one registry’s classification. Other kennel clubs may use different language or rules, so “non-standard” should not be presented as a universal international designation. It also does not turn a dog of that color into another breed.

German Shepherds have a double coat and occur in multiple colors and patterns. The same color can appear in different pedigrees. A sable coat is not proof of Czech, DDR, or West German working ancestry, just as a black-and-red saddle is not conclusive evidence of West German show ancestry.

The same limitation applies to:

• Back slope
• Rear angulation
• Head width
• Bone
• Frame
• Ear size
• Facial expression
• Gait
• Overall “serious” or “showy” appearance

An experienced observer may say that a dog resembles a particular tradition. That is different from establishing ancestry. If ancestry matters, request a documented pedigree and breeder records. If those records are unavailable—as is common with rescue dogs—describe what is known instead of assigning a line from photographs.

How Much Does a Line Predict About an Individual Dog?

Breeding goals matter. When breeders repeatedly select for certain structures, motivations, activity patterns, or performance traits, those characteristics may become more common within a population. That makes line labels useful background information.

But frequency is not destiny.

A line label cannot establish how a particular puppy will behave as an adult. It cannot tell you with certainty how quickly the dog will learn, whether it will settle in the house, how it will respond to pressure, what it will look like at maturity, or whether it will succeed in demanding work.

Factors to consider together include:

• The individual dog’s inherited traits
• The temperaments of both parents
• Adult relatives and previous offspring
• The breeder’s selection decisions
• Prenatal and early rearing conditions
• Socialization and exposure
• Training history and methods
• Physical health
• Current behavior in relevant environments
• The owner’s routine, handling, and expectations

No single factor has a supported universal weighting. Even observations such as recovery after novelty, play motivation, or puppy engagement should be treated as pieces of information rather than reliable forecasts of adult suitability.

Show dogs with obedience, tracking, herding, or other performance titles demonstrate why “show” and “work” are not mutually exclusive. Conversely, a working pedigree without relevant individual evaluation is evidence of ancestry and possible potential—not proof that the dog can perform police work, protection, IGP, or search and rescue.

The reverse assumption also fails. A show pedigree does not guarantee a calm, uncomplicated companion.

Myth versus fact

Myth: There are five separate German Shepherd breeds. Fact: There is one German Shepherd Dog breed. The five familiar names are commonly discussed breeding lines.

Myth: A sloped back proves a show pedigree. Fact: Structure may resemble a show-influenced type, but stance, age, conditioning, and individual variation also affect appearance.

Myth: Dark sable proves DDR ancestry. Fact: Dark sable occurs in more than one population. Documentation is needed to support a specific ancestry claim.

Myth: Every working-line German Shepherd is a protection dog. Fact: Protection work requires suitable individual health and temperament, specialized training, evaluation, and competent handling.

Myth: Every show-line German Shepherd is low-energy. Fact: Show lines may be described as less intense on average, but individual dogs can still need substantial exercise, training, and mental engagement.

The available evidence does not justify declaring one line healthier, longer-lived, more intelligent, better with children, or categorically easier to train. Ask what evidence describes the individual dog and its close family—not what the line is supposedly always like.

Choose for Lifestyle and Purpose, Not for a Label

There is no universally best German Shepherd line. There are only better or worse matches for a particular owner, household, and purpose.

Start by defining the intended role honestly:

• Household companion
• Conformation
• Obedience
• Scent work
• Tracking
• Herding
• Agility
• IGP
• Search work
• Professional detection or patrol work
• Carefully managed protection sport
• Another specific activity

Wanting an “active dog” is not the same as being prepared to train several times each week toward a working title. Wanting an imposing-looking dog is not a sound reason to select for intense prey-related or defensive behavior.

Lifestyle decision checklist

Experience

• Have you raised a large working or herding breed through adolescence?
• Can you recognize rising arousal, fear, frustration, and overstimulation?
• Are you willing to seek qualified help before a manageable problem becomes established?

Daily exercise

• How much exercise can you provide every day rather than only on weekends?
• Can you adapt activity to the dog’s age, health, and conditioning?
• Are you prepared for a dog that may not be satisfied by access to a yard?

Mental work

• Will the dog receive structured training, sniffing, problem-solving, or task-based activity?
• Can you teach calm behavior instead of trying to exhaust the dog continuously?
• Are you prepared to maintain training throughout adulthood?

Access to suitable instruction

• Are competent trainers, clubs, or activity instructors available locally?
• If you want to pursue IGP, tracking, or search work, can you attend training consistently?
• Does the instructor have relevant experience with German Shepherds and the intended discipline?

Household routine

• How long will the dog regularly be alone?
• Are children, older adults, visitors, or other animals part of the home?
• Can everyone follow consistent management and training rules?

Space and environment

• Is there secure space for exercise and training?
• Can you safely manage a large adolescent in shared hallways, elevators, busy streets, or unfenced areas?
• If the home is small, can the routine still provide suitable outdoor activity and quieter decompression?

Tolerance for adolescence

• Can you manage pulling, jumping, vocal behavior, chewing, boundary testing, and uneven concentration?
• Are you prepared to supervise interactions and prevent repeated unwanted behavior?
• Can you remain consistent when progress is slow?

Someone pursuing intensive sport or professional work may reasonably investigate West German working, Czech, DDR-influenced, or blended working pedigrees. The goal should not be to buy the most intense dog available. It should be to find an individual whose health, drives, sociability, resilience, environmental responses, and trainability suit the task and handler.

A companion buyer may investigate breeders selecting for moderate, stable household temperaments. That could include show-oriented, companion-oriented, working, or blended pedigrees. No “show line” or “pet line” label guarantees low activity or easy behavior.

Novice owners should be especially cautious about choosing a puppy because it is dark, large-headed, supposedly rare, intimidating, or advertised as naturally protective. Protection suitability cannot be inferred from marketing or ancestry alone and may require evaluation by a qualified, discipline-specific professional.

Ask about both parents and adult relatives:

• Do they settle when nothing is happening?
• How much activity do they need to remain manageable?
• How do they behave around visitors and in public?
• What challenges appeared during adolescence?
• What are previous puppies like as mature adults?
• Have any previous placements proved unsuitable, and why?

Treat the breeder’s answers as evidence to investigate, not guarantees.

Rescue dogs and unknown pedigrees

A German Shepherd does not need a documented line label to be assessed thoughtfully. When ancestry is unknown, focus on what can actually be observed:

• Current energy and ability to settle
• Comfort around unfamiliar people
• Responses to dogs and other animals
• Recovery after novelty or surprise
• Food, toy, or movement motivation
• Handling tolerance
• Physical health and mobility
• Existing training
• Behavior in the environment where the dog will live

Significant behavior concerns or working-suitability questions may require a qualified trainer, veterinary behaviorist, or relevant working-dog specialist.

If the household cannot provide sustained exercise, training, supervision, and mental engagement, reconsider whether a German Shepherd—regardless of line—is the right match.

How to Evaluate a Breeder and the Evidence Behind a Puppy

A line label should begin a conversation, not end one. A breeder should be able to explain what the parents were selected to do, how their health and temperament were evaluated, and why the pairing was chosen.

Look for:

• A documented pedigree
• Clear, specific breeding goals
• Verifiable health-screening records
• Stable adult behavior in ordinary settings
• Information about adult relatives and previous offspring
• Appropriate living and rearing conditions
• Age-appropriate socialization and exposure
• Honest discussion of variation within the litter
• A reasoned process for matching puppies to homes
• Willingness to discuss limitations rather than promise perfection

These are practical screening questions, not a scientifically validated scoring system. Paw Primer’s scope is to help owners identify what they can reasonably evaluate while recognizing when professional assessment is needed, as explained in its editorial approach.

Health screening

The Royal Kennel Club lists hip and elbow dysplasia screening as minimum pre-breeding tests for German Shepherds. It also lists degenerative myelopathy DNA testing and eye testing as Best Practice measures (Royal Kennel Club health recommendations).

Requirements and recommendations can differ by country, registry, and breed organization. Buyers should verify the current guidance that applies where they live and discuss individual health concerns with a veterinarian.

Screening reduces uncertainty; it does not eliminate it. Hip screening should not be presented as a guarantee that every resulting puppy will avoid hip dysplasia. A former working-line breeder’s selection guide likewise recommends considering pedigrees, hip results, adult temperament, kennel conditions, and individual puppy behavior rather than relying on one credential (breeder and puppy selection guidance).

Ask to see the actual records rather than accepting “health tested” as a complete answer. Check which organization recorded the result, whether the dog can be independently identified, and whether both parents were assessed.

Registration is not a complete quality test

Registration may document that a dog and its parents are recorded with a registry. It should not be treated as proof of health, stable temperament, working ability, responsible selection, or appropriate puppy rearing.

A Wildhaus kennel-authored guide characterizes AKC registration as confirmation of registered purebred parentage rather than evidence that breeding dogs passed health or temperament testing. This is a breeder’s interpretation, not a substitute for an official registry policy. The practical conclusion is narrower: request separate, verifiable evidence of health and temperament instead of assuming registration supplies it.

Questions to ask the breeder

1. What were the parents bred to do? Look for a specific answer: conformation, IGP, tracking, herding, detection, companionship, or another defined goal.

2. Which health results can I verify? Ask for records for both parents and confirm which recommendations apply in your country.

3. How do the parents behave outside training or the show ring? A polished performance does not by itself explain how a dog behaves at home.

4. What variation have you seen in previous offspring? A useful answer should acknowledge differences in activity, confidence, sociability, trainability, and maturity.

5. Why is this individual puppy a possible match for this home? The breeder should connect observed behavior and family history with your routine and goals while avoiding guarantees.

6. What support is available after placement? Ask how the breeder handles training, health, or compatibility problems and whether the contract addresses return or rehoming.

If a puppy is marketed as Czech, DDR, or West German, request pedigree documentation. Color, head size, bone, back shape, and promotional language are not proof.

Practical warning signs include:

• Pressure to choose mainly by color or supposed rarity
• Guaranteed protection ability
• Categorical promises about temperament
• Claims that every puppy will suit every family
• Refusal to share health records
• Reliance on registration as the only quality claim
• Marketing aggression or suspicion as automatically desirable
• No explanation of how puppies are matched to homes
• Unwillingness to discuss weaknesses in parents or prior offspring

These are cautionary heuristics rather than independently validated rules. Consider the complete picture and seek professional help where the intended role carries substantial behavior or safety demands.

Frequently Asked Questions

How many types of German Shepherd are there?

There is no single official number of German Shepherd “types.” One commonly used framework identifies five lines: American show, West German show, West German working, East German or DDR working, and Czech working (five-line breeder classification).

Other sources use broader or narrower groupings. Some add an American pet category, while others consolidate dogs into show and working lines or three larger categories. There is one German Shepherd Dog breed, with multiple breeding traditions, coat varieties, colors, and mixed-line pedigrees.

Which German Shepherd line is best for a family?

No line is automatically best for every family. Prioritize the individual dog’s temperament and activity level, the behavior of adult relatives, documented health screening, breeder transparency, and compatibility with the owners’ experience.

Some show- or companion-oriented breeders may select for more moderate intensity, but a show label does not guarantee an easy dog. Some working-line dogs live successfully in capable family homes, while high-drive individuals may require considerably more structure and training.

Can you identify a Czech, DDR, or working-line German Shepherd by appearance?

Not reliably. Dark sable coloring, heavy bone, a broad head, moderate angulation, or an athletic frame may resemble traits associated with a working tradition, but none proves ancestry.

Modern pedigrees may also combine Czech, DDR, and West German working dogs. A documented pedigree and reliable breeder records provide stronger evidence than photographs or visual assessment.

Is a long-haired or all-black German Shepherd a separate breed?

No. Long hair is a coat-length variety within the German Shepherd Dog breed, and black is a coat color. The same principle applies to sable, bi-color, black and tan, white, and other colors: they do not create separate breeds or establish a bloodline.

A long-haired or all-black dog may have show, working, blended, companion-bred, or undocumented ancestry.

What health tests should a German Shepherd breeder provide?

Ask for verifiable hip and elbow screening results for both parents. Depending on the country and applicable breed organization, recommendations may also include degenerative myelopathy DNA testing and eye testing.

Requirements differ, so confirm current guidance with the relevant kennel club or breed organization and discuss individual health questions with a veterinarian. No screening program guarantees a healthy puppy, but documented results provide more useful evidence than registration, line labels, or general assurances.

The corrected premise is simple: buyers are not choosing among several German Shepherd breeds. They are choosing an individual dog shaped partly by a particular breeding history and set of priorities.

A line label can guide the first questions. It should never outweigh verifiable health records, stable adult temperament, breeder transparency, realistic activity and training demands, and the observed qualities of the dog itself.

This article provides general selection information rather than an assessment of an individual dog, consistent with Paw Primer’s informational-use limitations. Individual health questions belong with a veterinarian. Significant behavior concerns and evaluations for protection, police, search, or demanding sport work may require a qualified trainer, veterinary behaviorist, or relevant specialist.
