Is Monstera (Swiss Cheese Plant) Toxic to Dogs?
Toxic☠️ Toxic to dogs — avoid
Monsteras are toxic to dogs — chewing any part causes intense mouth irritation and drooling from calcium oxalate crystals.
Instagram's favorite plant is another oxalate aroid: bite a leaf and thousands of microscopic crystals embed in the tongue and gums. Dogs typically yelp, drool, and quit after one mouthful, so most cases are painful rather than dangerous. Large ingestions or throat swelling are the escalation points.
What makes it dangerous: Insoluble calcium oxalate crystals
Symptoms to watch for
- Immediate oral pain
- Drooling
- Pawing at face
- Vomiting
What to do right now
- Rinse mouth, offer water
- Watch for swelling; bland food for a day
- Vet for breathing changes or persistent symptoms
