My dog ate Borage - what should I do?
Borago officinalis
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Drooling, vomiting, diarrhea, and potential lethargy or signs of abdominal pain.
Escalation note
While symptoms are often mild, the presence of pyrrolizidine alkaloids warrants caution; consult a veterinarian for professional guidance.
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).
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.
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.
