Are Bully Sticks Good for Puppies? Not the Best Teething Choice

Bully sticks are not the best first choice for a teething puppy. They can provide chewing enrichment, but their toughness, calories and swallowable ends create risks. For an older puppy, an occasional supervised chew may be an option if your vet considers it suitable for that puppy’s teeth, digestion and chewing style. A veterinarian-authored guide to puppy bully sticks recommends waiting until adult teeth have come in.

If your puppy has already swallowed a large piece, call your vet now—even if they seem comfortable. Trouble breathing or persistent gagging after chewing needs emergency veterinary care. Swallowed-object guidance advises contacting a vet rather than waiting for symptoms.

Is there a safe age to start?

Bully sticks, also called pizzle sticks, are dried bull or steer penis. They are edible animal-based treats, not a necessary part of puppy nutrition.

Adult teeth usually finish coming in around six months, but six months is not a safety guarantee. Hard chews can fracture both baby and adult teeth. VCA advises choosing chews that bend rather than rigid objects, and supervising even recommended toys. For a young puppy still losing teeth, a pliable puppy chew toy is a better starting point. See VCA’s puppy teething guidance.

If you are unsure whether a tooth has fallen out normally or broken, our guide to normal puppy tooth loss and warning signs explains what to look for.

What are the main risks?

• Tooth injury: A puppy that bites hard into a tough stick can damage a tooth. Adult teeth do not remove this risk.
• Choking or a lodged piece: A large chunk can get stuck in the throat or esophagus—the tube leading to the stomach. Being digestible does not mean a whole piece is safe to swallow.
• Stomach upset: A new treat can cause vomiting or diarrhea. Avoid bully sticks if your puppy has a known beef allergy; ask your vet first if they have digestive problems or a prescribed diet. These risks are discussed in the veterinarian-authored puppy guide.
• Extra calories: In a small 2013 study, the five sticks analyzed for nutrition varied substantially in calories per stick. Do not assume one stick equals one small snack. All treats together should supply no more than 10% of daily calories, with the rest coming from complete and balanced food appropriate for your puppy. Ask your vet how a chew fits alongside training treats. See the original bully-stick study and UC Davis treat guidelines.
• Bacteria: That study also detected bacterial contamination in some of 26 sticks tested. It does not establish today’s contamination rate, but supports washing hands after handling them. Tufts advises people at high risk of infection—including very young children, older adults, pregnant people and immunocompromised people—to avoid contact with raw animal-based treats. See Tufts’ explanation.

If you decide to offer one

Ask your vet whether the product’s hardness and size suit your puppy. Skip it if your puppy tries to gulp chews rather than gnaw them.

Stay close and watch throughout—not just in the same room while distracted. Introduce the treat gradually, limit how much your puppy eats, and remove it before it becomes small enough to fit entirely inside their mouth. Stop if your puppy bites off chunks, seems uncomfortable, or develops vomiting or diarrhea. These precautions follow veterinary guidance on swallowed objects and the puppy-specific guide above.

For everyday chewing, choose a puppy-sized rubber toy with some bend or a surface you can indent with a fingernail. Remove it if pieces break off. A suitable food puzzle using part of the puppy’s normal meal can also provide enrichment without adding extra treats. VCA’s toy advice emphasizes that toys still require supervision; its puppy care guidance also recommends puzzle feeding.

Watch, call a vet, or go now?

Watch at home: If your puppy chewed normally, did not gulp a chunk, and remains comfortable with normal appetite and energy, remove the chew and observe for digestive or mouth discomfort.

Call your vet promptly: Call now after a large piece is swallowed; do not wait for symptoms or assume it will dissolve. Also contact your vet for vomiting, recurring diarrhea, reduced appetite, a suspected broken tooth, or mouth pain. Do not induce vomiting unless a veterinarian instructs you to. Swallowed-object guidance explains why early advice matters.

Go to emergency care now: Trouble breathing, collapse, persistent gagging or retching, or difficulty swallowing after chewing may indicate a lodged piece. Repeated vomiting with abdominal pain or marked lethargy also needs urgent assessment. The puppy bully-stick guide lists esophageal warning signs; Cornell’s obstruction guidance explains the digestive signs.

This is general care guidance, not a diagnosis for an individual puppy.
