Dogs that chew Monstera get a sharp burst of mouth pain almost immediately — the leaves contain insoluble calcium-oxalate crystals that embed in the tongue, lips, and gums. It is mildly toxic, not deadly: most dogs spit the leaf out, drool a lot, and are back to normal within a day or two.
Pawing at the mouth, foamy drooling, head-shaking, decreased appetite, vomiting (sometimes with bits of plant), and difficulty swallowing. Watch the muzzle and tongue for visible swelling; rare cases involve airway swelling and breathing difficulty.
Signs typically appear within minutes of chewing. With supportive care, most dogs recover within 24–48 hours; persistent or worsening signs warrant a vet visit.
Call your vet or a poison hotline immediately if drooling does not stop within an hour, the dog will not eat or drink, the tongue or muzzle is visibly swollen, or there is any change in breathing.
Wipe any plant material out of your dog's mouth with a damp cloth. Offer cool water; a small amount of milk or yogurt can ease the burning by binding oxalate crystals. Then call ASPCA Animal Poison Control (888-426-4435) or the Pet Poison Helpline (855-764-7661). Do not induce vomiting unless a veterinarian instructs you to.
