There are close to 60 different species of Dieffenbachia plants!Will my dog get sick if he eats a Dieffenbachia plant?Consumption of these plants by cats and dogs causes severe irritation to the oral mucosa (traumatic stomatitis), esophagus, and stomach due to insoluble calcium oxalate crystals. Imagine chewing on fiberglass, or glass itself! When your pet chews on the leaves, it releases the calcium oxalate crystals, and they penetrate the tissues of the mouth and consequently the gastrointestinal tract. Dogs and cats that chomp on these plants will develop painful ulcerations in their mouths that cause an intense burning sensation within minutes.Signs of Dieffenbachia Toxicity in Dogs and CatsYou may notice your pet drooling excessively, licking, lip-smacking, avoiding food and water, and being generally miserable. Some animals may paw at their mouths, vomit, or in severe cases develop swelling of the upper respiratory tract causing difficulty breathing (uncommon).Raphides - long, skinny, needle-like formations of calcium oxalate crystals - are responsible for the pain in the mouth and for the origin of the nicknames “Dumb Cane” (preventing speaking due to pain in the mouth).What should I do if my pet eats part of this plant?Fortunately, Dieffenbachia is not severely toxic, and pets usually get better with no significant consequences. However, a trip to the vet is advised to provide your pet with pain medication until the oral ulceration resolves. Your vet may also prescribe gastroprotectant medication to help protect the lining of the esophagus and stomach.Since these plants are quite common, and many people have them in their household, it is essential that you keep them in a place where your pets cannot get to them. Even a small bite of the tip of a leaf or drinking water that has leaked from these plants can cause oral irritation.For more information and pictures of Dieffenbachia, check out these links:ASPCA: DieffenbachiaPet Poison HelplineInsoluble OxalatesRead more in our series of poisonous plants for your dog and cat:Poisonous Plants for Dogs and Cats: TulipsPoisonous Plants for Dogs and Cats: PhilodendronPoisonous Plants for Dogs and Cats: AzaleaStill have questions?Schedule a video consult to chat with one of our vets.
