Can Dogs Eat Asparagus? In Moderation

Why it’s fine in small amounts

Asparagus is not poisonous to dogs. Both the AKC and PetMD say the spears are fine, though the way you prepare them matters. They are low in fat and sugar and carry fiber, antioxidants, several vitamins and minerals such as potassium, zinc and iron.

The trouble is texture. Raw asparagus is tough and fibrous, which makes it hard to chew and a choking or blockage risk. Cooking until tender solves much of that. Too much can bring gas, vomiting or diarrhea, and asparagus can give urine a strong smell. PetMD calls this smelly but not dangerous.

The AKC warns that the asparagus fern, the feathery inedible part of the plant, is toxic and can bring on vomiting, diarrhea and intense belly pain, so fence off an asparagus bed. The ASPCA also lists the ornamental asparagus fern (Asparagus densiflorus) as toxic to dogs: its berries can cause vomiting, belly pain or diarrhea, and repeated skin contact can cause allergic dermatitis. The AKC's produce guide adds that there is really no benefit to feeding the spears, since cooking them soft strips much of their nutritional value.

Benefits

Low in fat and sugar, with fiber and antioxidants
Provides vitamins A, C and K and minerals such as potassium, zinc and iron
A softly cooked spear is an easy topper for regular meals

Risks

Raw spears are tough and can cause choking or an intestinal blockage
Too much can cause gas, vomiting or diarrhea
Can make urine smell strong, which is harmless but unpleasant
Asparagus fern is toxic to dogs; its berries can cause vomiting, abdominal pain or diarrhea, and repeated skin contact can irritate the skin
Butter, oil, salt, garlic or onion added in cooking are not safe

How to serve it safely

Wash the spears, snap off the woody ends, and steam or boil them until tender with no butter, oil or seasoning. Cool them, then chop into small bite-size pieces and use as a topper or snack. If you do serve raw, chop it very small and watch your dog while it eats.

PetMD's guide runs from about a teaspoon for a dog under 20 lb (9 kg) to two or three tablespoons for a dog over 90 lb (41 kg). Treats should stay under about 10% of daily calories. If your dog gets gas or a loose stool, switch to an easier raw crunch such as celery, carrots or cucumber, which the AKC suggests.

If your dog already ate it

If your dog ate a few plain spears, expect nothing more than possible gas and smelly urine.

Call your vet if your dog swallowed large raw pieces and is gagging, vomiting or painful, or if vomiting or diarrhea continues. If your dog chewed asparagus fern or ate its berries, call your vet, ASPCA Animal Poison Control at (888) 426-4435 or Pet Poison Helpline at (855) 764-7661 (US; fees may apply). Do not make your dog vomit at home.
