Here's why:
* Choking hazard: Dominoes are small and can easily be swallowed whole, posing a serious choking risk.
* Digestive issues: Dominoes are made of wood or plastic, which are not digestible by dogs. This can lead to blockages in the digestive system, requiring expensive and potentially dangerous surgery.
* Toxicity: Some dominoes may contain paint or other materials that can be toxic to dogs.
Always provide your dog with safe, dog-approved treats and food. If you're unsure about something, consult your veterinarian.
