| Short answer | Yes, in small amounts. The AKC says asparagus is not toxic to dogs. |
| How to serve | Cooked (boiled or steamed) with no butter or oil, or raw but chopped into small pieces. |
| Biggest risk | Swallowing raw spears whole could choke a dog, and raw asparagus can be hard to digest. |
| Watch out | Asparagus fern, the garden and houseplant, is toxic to dogs (ASPCA). |
Asparagus is a common vegetable, so it is natural to wonder whether your dog can share a spear.
The American Kennel Club says: “Asparagus isn’t toxic to dogs, but there are a few things you should keep in mind before feeding them this vegetable.” It says raw asparagus would be very difficult to chew, and that a dog might swallow it whole and possibly choke, so it is better to feed it cooked.
The plant called asparagus fern is a different matter. The ASPCA lists it as toxic to dogs.

Is asparagus safe for dogs?
Yes, the vegetable itself is not toxic, according to the American Kennel Club. Offer only a small amount, as a treat and not as a meal, and try one new food at a time. We found no primary source giving a safe weight of asparagus for a dog of a given size, so we do not give one. Ask your vet if your dog has a health problem.
How to prepare asparagus for dogs
- Cook it by boiling or steaming. The AKC says not to use butter or cooking oil, as these can make a dog sick.
- If you serve it raw, chop it into small, bite-sized pieces.
- Leave out garlic, onion, salt and sauces.
- If your dog has vomiting, gas or diarrhoea after raw asparagus, the AKC suggests trying it lightly cooked next time.
The AKC also suggests celery, carrots or cucumber if your dog finds raw asparagus hard to digest, cut into bite-size chunks to avoid choking.
Asparagus fern is toxic
The ASPCA lists asparagus fern (Asparagus densiflorus) as toxic to dogs and cats. Its listed clinical signs are allergic dermatitis with repeated skin contact, and, if berries are eaten, stomach upset with vomiting, abdominal pain or diarrhoea.
The AKC says the same of the inedible part of the asparagus plant and advises fencing off a garden asparagus patch so your dog cannot reach it. Keep ferns and berries out of reach, indoors and outdoors.
Why does asparagus change the smell of urine?
The AKC notes that asparagus can make urine smell unpleasant, in dogs as in people. For a housetrained dog this should not be a problem.
What to do
- If your dog is choking, gagging or has pale or blue gums, go to an emergency vet now.
- If your dog ate asparagus fern leaves or berries, call your vet or a pet poison helpline. 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.
- If your dog swallowed raw spears whole, watch for repeated vomiting, loss of appetite or a painful belly, and call your vet if you see them.
- Do not make your dog vomit unless your vet tells you to.
Canned asparagus
We found no primary source on canned asparagus for dogs. Canned vegetables are often packed in salt, so offer only plain, home-cooked asparagus, and ask your vet before offering anything else.
