Pizza is not a single food but a stack of concerns: a fatty, salty base, cheese for lactose-sensitive dogs, and, most important, a sauce usually made with garlic and onion. A nibble of plain crust is low-risk; a loaded slice is worth more care.

Why Pizza needs caution
Pizza combines fat and salt with cheese (a lactose and fat load) and a tomato sauce almost always made with garlic and onion, which damage canine red blood cells. Fatty, meaty toppings add a pancreatitis risk.
Signs to watch for
Upset stomach, vomiting, diarrhea; with a garlic or onion dose, weakness or pale gums later
What to do next
If it was plain crust, watch at home; if it had sauce, cheese, and toppings, note the amount and your dog's weight and call your vet, especially for a small dog.
The plain dough is the least of it; the flavor is where the risk lives.
1. Garlic, onion, and fat
Pizza sauce is typically made with garlic and onion, which harm canine red blood cells, and cheese and meat toppings pile on the fat that can trigger pancreatitis. How a fatty, rich meal triggers pancreatitis →

A small piece of plain crust, for a healthy dog, is generally fine to watch at home.
When should I call the vet?
A slice with sauce, garlic, or onion; a fatty or meaty slice; a small dog; or signs of vomiting, a painful belly, weakness, or pale gums.
