Can Dogs Eat Stuffing? No: Onion, Garlic and Leek Are In It
Quick answer
No. PDSA warns that stuffing and gravy often contain onion, leeks and garlic, which can be deadly to both dogs and cats, and that every part of these plants stays toxic when cooked or dried. Signs can take one to five days to appear. Sage itself is on the ASPCA non-toxic list; the onion it is paired with is the problem.

Stuffing looks like bread, and bread is not the problem. The onion, garlic or leek cooked into it is, and cooking does not make them harmless.

What is published
PDSA says: “Stuffing and gravy often contain onion, leeks and garlic, which can be deadly to both cats and dogs.” A PDSA vet names sage-and-onion stuffing among the Christmas foods that can be harmful. Sources: PDSA, Fatal foods for furry friends this Christmas; PDSA, Dog dodges death after downing lethal pie.
Cooked and dried still count
PDSA says all parts of the onion family are toxic to dogs, even when cooked or dried. That covers fried onion, onion powder, garlic granules and dried stuffing mixes. Source: PDSA, Onion and garlic poisoning in dogs. More on onions and garlic.
Why waiting does not help
PDSA says symptoms may occur one to five days after eating onion, garlic or leek. A dog that seems fine on Christmas evening has not shown that it is fine. PDSA advises contacting your vet as soon as possible.
Sage, butter and fat
Common sage is listed by the ASPCA as non-toxic to dogs and cats, so the herb is not the issue. Fat is: PDSA lists recently eating high-fat foods, such as butter, among the risk factors for pancreatitis in dogs. Sources: ASPCA, Sage; PDSA, Pancreatitis in dogs.
If your dog already ate some
Phone your vet, an emergency vet or your national animal poison line, and tell them what was in the stuffing if you know, or bring the packet. My dog ate something explains the next few minutes.
What we could not source for this page
- No publisher we could reach gives a portion, a frequency or a safe amount, and neither do we.
- Shop-bought stuffing mixes vary, and we cannot tell you whether a given brand contains onion or garlic. The ingredients list on the packet can.
