Use caution

Can dogs eat mayonnaise?

Caution — a tiny lick is not usually toxic, but mayonnaise is fatty and offers no benefit to dogs.

What to do if eaten

If a dog ate a large amount or the product contains garlic, onion, or xylitol, contact a vet; seek advice for repeated vomiting or abdominal pain.

How to serve safely

Avoid feeding mayonnaise deliberately. Flavored mayo, aioli, dressings, and sandwiches may contain garlic, onion, chives, spices, or more salt. Rich foods can trigger digestive upset or pancreatitis in susceptible dogs.
