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
Oral irritation, intense burning and irritation of mouth, tongue and lips, excessive drooling, vomiting, and difficulty swallowing.
Escalation note
Ingestion typically leads to immediate discomfort due to the release of calcium oxalate crystals. Always consult with a veterinarian if you suspect your dog has consumed this plant.
First aid at home
Call ASPCA Animal Poison Control at (888) 426-4435 or your veterinarian as soon as possible. Do not induce vomiting unless a veterinarian instructs you to.
What to watch for
Most-common to least: sudden, heavy drooling and pawing at the mouth, oral and lip swelling, vomiting, and difficulty swallowing. A dog that chewed and kept chewing may show pronounced swelling and refuse food and water. Systemic toxicity is uncommon.
Time window
Signs appear almost immediately after chewing. Pet Poison Helpline describes the mechanism as immediate tissue penetration; symptom duration is not well documented but typically resolves within hours of supportive care.
When to call the vet
Call your veterinarian or ASPCA Animal Poison Control (888-426-4435) for any persistent drooling, visible mouth or tongue swelling, vomiting, or refusal to eat or drink. Difficulty breathing or noisy breathing — rare — means call immediately.
What this means for your dog
Dogs that chew lacy tree philodendron get an immediate, painful mouthful — the insoluble calcium oxalate crystals stab into the tissue of the mouth and tongue on contact. The reaction is dramatic, but most dogs spit out the leaf and recover with supportive care; the bigger concern is when a determined chewer keeps going.
