Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.

What this means for your dog

Borage is toxic to dogs per the ASPCA, with tannins and mucilage causing GI upset and contact dermatitis. Most dogs that nibble a leaf or two recover with supportive care, but larger meals stress the liver via the plant's alkaloids and warrant a vet visit. Bigger or younger dogs handle small amounts better than tiny breeds.

What to watch for

Drooling, vomiting, and diarrhea are the headline signs. Some dogs develop dermatitis on the muzzle, lips, or paws from the bristly leaves. With a larger ingestion, watch for lethargy, dehydration (sticky gums, slow skin tent), and loss of appetite — these point to the alkaloids irritating the liver.

Time window

Veterinary references note that, with moderate consumption, most dogs recover completely within 24–48 hours when treated promptly. Exact time-to-onset isn't well characterized in the literature.

When to call the vet

Call your vet if vomiting or diarrhea continues past a couple of episodes, your dog seems weak, refuses food, or you suspect more than a mouthful was eaten. For any known large ingestion, call right away — don't wait for symptoms.

First aid at home

Rinse your dog's mouth and any contact areas of skin with lukewarm water to remove plant residue. Do not induce vomiting at home — Wag! veterinary guidance specifically advises against induced vomiting for borage because it can worsen the irritation. Save a plant sample, then call your vet or ASPCA Poison Control (888-426-4435).
