Frequently asked questions

Is the Monstera (Swiss Cheese Plant) poisonous to dogs?
Yes. The ASPCA lists Monstera deliciosa as toxic to dogs. All parts of the plant contain insoluble calcium oxalate crystals that release on chewing and embed in the mouth and throat tissues, causing immediate pain and irritation.
What happens if my dog chews on a Monstera leaf?
Chewing typically causes intense burning and irritation of the mouth, tongue and lips, excessive drooling, oral irritation, vomiting, and difficulty swallowing. Signs usually appear right away. Most cases are mild-to-moderate because the immediate pain discourages large amounts being eaten, but heavy oral or throat swelling can rarely affect breathing or swallowing and warrants prompt veterinary attention.
Are Monstera fruit, roots and aerial parts also a risk to dogs?
The leaves, stems, and unripe fruit all contain insoluble calcium oxalates and should be treated as toxic to dogs. Keep the whole plant, fallen leaves, and trimmings out of your dog's reach, and do not let a dog access any part of the plant.
