| Short answer | We found no primary source on plain artichoke hearts for dogs, so ask your vet before offering any. |
| Marinated or jarred hearts | Avoid. They are often packed with garlic or onion, which are toxic to dogs. |
| Biggest risk | Garlic and onion seasoning (AKC), not the artichoke itself. |
| If your dog ate marinated hearts | Check the label for garlic and onion and call your vet. |
Artichoke hearts are easy to find in jars and cans, so dogs often get the chance to steal one from a plate or an antipasto tray.
We looked for a primary source (the AKC, ASPCA, PetMD or a vet body) that says whether plain artichoke hearts are safe for dogs, and we did not find one. So this page does not claim a safe portion size.
What we can source is the risk in the jar. Marinated hearts are often seasoned with garlic or onion, and the American Kennel Club says all parts of the onion plant are toxic to dogs, including processed powders.
This page is general information, not veterinary advice. If you are worried about your dog, call your vet.
Why marinated artichoke hearts are risky
- Onion: the American Kennel Club says onions contain N-propyl disulfide, which damages red blood cells and leads to anaemia in dogs.
- Garlic: the American Kennel Club says dogs should avoid garlic and other alliums, which contain thiosulfate that is toxic to dogs and can cause blood cell damage.
- Powders: the AKC onion page says onion and garlic powders are even more potent than fresh onions, so check labels for them.
We found no primary source on the oil or salt in jarred or canned hearts, so we give no figures. Heavily salted or oily food is a good reason to ask your vet before sharing.
Signs to watch for
The American Kennel Club lists these signs of anaemia after onion: lethargy, weakness, decreased appetite, pale gums, fainting and reddish urine. It adds vomiting, a raised heart rate and panting. The AKC garlic page says stomach upset can appear within hours, while the more serious signs can show up two to five days later.
What to do
- Find the jar or can and read the ingredients for garlic, onion, onion powder or garlic powder.
- Call your vet or a pet poison helpline and tell them the product, how much your dog ate and your dog’s weight. In the US the ASPCA Animal Poison Control number is (888) 426-4435 (a consultation fee may apply); elsewhere, use your local vet or poison service.
- Go to an emergency vet if your dog has pale gums, weakness, fast breathing or reddish urine.
- Do not make your dog vomit unless your vet tells you to.
Plain artichoke hearts
Plain hearts with no garlic, onion, salt or oil are the lower-risk version. Because we found no primary source, we do not give a serving size, how often to feed them, or a nutrient list. Ask your vet whether they suit your dog, especially one with a health problem.
Canned, frozen or in water
We found no primary source on canned or frozen artichoke hearts for dogs. Read the ingredient list and keep any garlic, onion or seasoning away from your dog.
