Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Pizza is not safe for dogs. The combination of garlic, onion (both toxic), high-fat cheese, salt, processed meats, and often spicy toppings makes pizza a hazardous food for dogs. The dough can cause bloating and stomach issues. Even plain cheese pizza has too much fat, sodium, and calories. Garlic and onion are present in nearly all pizza sauces and are toxic to dogs even in small amounts. If your dog steals a bite of pizza, monitor for symptoms of garlic/onion toxicity.
What You Should Know
Pizza should be kept well away from dogs. If your dog has eaten pizza, watch for symptoms such as vomiting, diarrhea, lethargy, or loss of appetite. In an emergency, contact your veterinarian or an animal poison helpline straight away.
