Dogs that chew Alocasia leaves or stems get a sudden mouthful of insoluble calcium oxalate crystals — sharp little needles that turn one bite into a yelp. Most cases pass with a sore mouth and a vet phone call, but big mouthfuls (especially from puppies) can drive heavy vomiting and, rarely, airway swelling. Treat any chewing as a same-day vet call.
Sudden drooling, lip-smacking, and head-shaking right after the bite. Pawing at the muzzle or rubbing the face on the carpet. Vomiting and reduced appetite. Less common but serious: swelling of the tongue, lips, or upper airway, or any sign of difficulty breathing.
Oral irritation usually starts within minutes and peaks in the first hour. Most dogs recover within 24 hours; vomiting or appetite loss can linger 24–48 hours after a larger ingestion.
Call your vet or ASPCA Poison Control at (888) 426-4435 right away. Drive to the emergency clinic if you see any facial swelling, repeated vomiting that won't stop, or labored breathing.
Take any plant fragments out of your dog's mouth. A small amount of xylitol-free milk, plain yogurt, or vanilla ice cream can help reduce oral burning (ASPCA guidance for insoluble-oxalate plants). Do not induce vomiting on your own. Call ASPCA Poison Control at (888) 426-4435 or your veterinarian.
