My dog ate Begonia - what should I do?
Begonia spp.
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, decreased appetite, and irritation of the mouth, tongue, and lips.
Escalation note
Ingestion of the plant, particularly the underground tubers, can cause significant oral discomfort. Consult your veterinarian if you suspect your dog has consumed this plant.
What to watch for
Expect drooling, vomiting, and decreased appetite shortly after ingestion. Some dogs paw at the mouth from oral irritation. NC State also notes the sap can cause skin irritation, so watch for redness or scratching where leaves contacted the muzzle, paws, or belly.
Time window
Oral signs typically begin within minutes of chewing; vomiting usually within an hour or two. Recovery time is not well documented in the cited sources, but uncomplicated leaf-ingestion cases generally improve within 24 hours.
When to call the vet
Call your vet right away if your dog dug up a tuber, is vomiting more than once, refuses food for more than a few hours, or develops swelling around the mouth. ASPCA Animal Poison Control: 888-426-4435.
What this means for your dog
Dogs — toxic. NC State Extension and ASPCA both flag begonia as a problem plant for dogs, with the underground tubers carrying the highest concentration of soluble calcium oxalates. Dogs are more likely than cats to dig and actually swallow tuber material, so the picture is often more severe than 'just chewed a leaf.'
