Can dogs eat pizza?
The full picture
Pizza is a compound problem for dogs. Base: bread (empty calories). Sauce: almost always onion and garlic (toxic). Cheese: high fat and lactose. Common toppings — pepperoni, sausage, bacon, ham — are all high-salt processed meats. Some toppings (onion, pineapple in excess) are separate issues. A small stolen bite isn't a medical emergency, but pizza should never be a deliberate treat.
If your dog has already eaten pizza
If your dog has eaten pizza with onion, garlic, or certain toppings, call your vet for advice. Plain cheese and bread pizza in small amounts is unlikely to cause an emergency but the sauce often contains alliums.
Risks to watch for
- Onion/garlic toxicity from sauce
- High salt and fat
- Lactose from cheese
- Pancreatitis
Safe portion size
None recommended.
Safer alternatives
- Plain cooked chicken
- Small piece of plain cheese
