Safety status
What this means for your dog
Mapleleaf begonia is toxic to dogs. The whole plant contains insoluble calcium oxalate crystals; the highest concentration is in the underground tubers, so dogs that dig up the pot are at greater risk than those that just nibble a leaf. Effects are usually painful but mild — airway swelling is the rare exception.
What to watch for
Intense oral pain, pawing at the mouth, drooling, and head shaking right after a bite. GI upset (vomiting, mild diarrhea, refusal to eat) often follows. Watch for any swelling of the muzzle, tongue, or throat or any change in breathing — those need immediate care.
Time window
Oral signs typically begin within minutes of chewing the plant. Most dogs recover within 24 to 48 hours of supportive care.
When to call the vet
Call your vet or Pet Poison Helpline (1-800-213-6680) for any begonia ingestion. Go in immediately for facial swelling, breathing changes, persistent vomiting, or if a small dog dug up and ate the tubers (highest toxin concentration).
First aid at home
Rinse your dog's mouth with cool water to flush out crystals, wipe the gums and tongue with a damp cloth, and offer fresh water (not milk). Call your vet before giving any medication. If your dog dug up the tubers, take a photo of the plant for the vet.
