10 Houseplants That Are Dangerous For Your Dog | Weddington Animal Hospital (2024)

Household plants can definitely liven up a home, but unfortunately, some species are dangerous for your pets and could even prove to be fatal if they’re ingested. The following list features plants which are poisonous to your pet due to the toxic substances they contain. Many of these plants are known by different names so it’s recommended that all pet owners familiarize themselves with them. It’s also an excellent idea to have a first-aid kit available for your pet in case of any type of mishap.

Lilies

The Lily family of plants is quite large, but some members of it are toxic to dogs and cats. The Mauna Loa, also known as the Peace Lily, is toxic to dogs and cats while the Stargazer and Easter Lilies are toxic for cats only. In fact, the Stargazer and Easter Lily could be fatal to cats if it goes untreated as it affects the animal’s appetite and kidneys. As for the Peace Lily, your dog or cat could start vomiting and have a problem swallowing due to irritated lips and tongue if it’s ingested.

Aloe Vera

While Aloe Vera is a wonderful plant for humans because of it’s skin-smoothing properties, but it has the opposite affect on pet dogs. The leaves contain a type of gel substance which isn’t harmful to your pet if it’s ingested, but the other parts of the plant can harm a dog’s digestive system.

Ivy (Hedera Helix)

We’ve all heard of Poison Ivy, but even regular Ivy can be harmful to a dog even though it’s quite pretty. A dog may develop a rash and/or breathing problems if the plant is eaten, but things can become much worse as Ivy can also lead to a coma or paralysis.

Jade (Crassula Ovata)

Dumb Cane (Dieffenbachia)

Dieffenbachia is generally known as Dumb Cane, Exotica or Tropic Snow and it’s poisonous to both dogs and cats. This plant’s harmful toxins can result in burning/swelling of the mouth and tongue as well as difficulty in swallowing, vomiting, and increased salivation. In some cases it can cause breathing difficulties and even death.

Elephant Ear (Caladium)

You may recognize this colourful plant species by its other common names such as Malanga, Via Sori, Pai, Taro, Cape or Ape. The chemicals found in it are similar to those in Dieffenbachia therefore the reactions are almost the same. This means your pet could suffer from oral problems, increased salivation or drooling, vomiting, and difficulty with swallowing.

Pothos/Devil’s Ivy (Epipremnum Aureum)

Also known as Satin or Silk Pothos, the plant is toxic to both dogs and cats as it can irritate the mouth and tongue. In addition, your pet may also suffer from vomiting, increased salivation and swallowing difficulties. The plant is related to Philodendron and can cause similar symptoms.

Sago Palm (Cycas Revoluta)

All parts of this exotic-looking plant can cause problems for your pet dog. This includes the roots, leaves and even the seeds. They’re all poisonous and ingesting any part of the plant can lead to diarrhea, vomiting and even liver failure.

ZZ Plant (Zamioculcas)

Sowbread (Cyclamen)

This flowering plant will brighten up any room, but it’s poisonous to dogs and cats. When swallowed it can result in increased salivation/drooling, diarrhea, vomiting, and abnormal heartbeat and/or seizures. It can even be fatal in severe cases.

If you’d like to decorate your home with plants there are several types which are safe for your pet dog as they contain no harmful toxins or chemicals. The most common and popular of these are
