Jade Plant

The jade plant (crassula ovata) is a lovely, low-care succulent. Jade plants are great for beginning plant owners, but they can be toxic for furry friends.

Unknown toxins in the jade plant can cause nausea, vomiting, and retching in dogs. If you own a jade plant, be sure to place it somewhere that your pet cannot ingest the leaves.

Eucalyptus Plant

Eucalyptus Plants are unique, fragrant, and eucalyptus derivatives have a variety of uses. But be careful; this strong-smelling plant can have a strong effect on dogs.

Just the smell of the eucalyptus plant can be irritating to dogs, and eating it can cause lethargy, excessive drooling, weakness, vomiting, or diarrhea. Because dogs are so sensitive to the smell of eucalyptus, you should avoid diffusing essential oils or burning candles that contain eucalyptus as well.

Peace Lily

The tropical peace lily plant produces beautiful flowers, but don’t let that beauty deceive you; for pets like dogs, the peace lily is very dangerous. Peace lilies of all types are harmful to dogs, but the Mauna Loa variety has been found to be the most toxic.

The insoluble calcium oxalates in the peace lily can cause digestive irritation, vomiting, swelling, and trouble swallowing if ingested by your pet. This plant also grows quite large, so if your dog is prone to plant chewing, it might be hard to keep the two apart. Be very careful with this plant!

English Ivy

English Ivy (hedera helix) is a shade-loving plant that is popular because it is both lovely to look at and easy to grow. However, the triterpenoid saponins in English Ivy make it moderately dangerous for dogs.

If your dog eats any part of your English Ivy plant, you may see vomiting, diarrhea, excessive drooling, or signs of stomach pain. For the health and happiness of your dog, you’ll want to keep this plant out of your home or put it in a spot your pup can’t reach.

The saponins in the cornstalk plant make it moderately toxic to dogs. If ingested, the cornstalk plant can cause your pet to vomit up blood. It can also cause vomiting, depression, lack of appetite, and excessive drooling.

Because the cornstalk plant is a bigger plant with large leaves, you may want to pass on this one if you own pets, since it will be hard to place it in an area they can’t reach.

Alocasia

The tropical alocasia plant is becoming more and more popular as a houseplant. Alocasia plants are flowering perennials with large, beautiful leaves. Sadly, those leaves, along with the roots and stems of the alocasia are moderately toxic to dogs.
