10 Toxic Plants to Remove from Your Dog’s Yard

Share with fellow dog lovers!

I have to admit that I love sago palms. I love the look of them and the tropical feel they give a yard. But we don’t have a sago palm — and we’ll never have a sago palm — because they’re deadly to dogs. They’re just one of the top 10 plants toxic to dogs we want you to make sure your dog has no access to in your yard or on your walks. And when you are out on a day trip or a hotel stay with your dog, make sure he doesn’t have access to these plants!

10 Plants Toxic to Dogs You Should Always Avoid

Azaleas (Rhododendron)

Ah, these beauties are very popular in East Texas and whole drives are devoted to seeing their spring blooms.

However, Azalea or Rhododendron is extremely toxic to pets causing problems that include damage to skeletal muscle, cardiac muscle and nerve functions.

What begins as digestive issues can progress to loss of coordination, stupor, a weak heartbeat, leg paralysis, and even death.

Castor Bean

Ricin — yes, that ricin — is made from castor beans. Eating just one ounce of of the seeds can cause excessive thirst as well as trembling, loss of coordination, breathing difficulties, coma, and death.


Watch for the bulbs of the daffodil; they’re the most toxic part of the plant. If your dog eats daffodil bulbs, it can result in cardiac arrhythmia, tremors, convulsions, and low blood pressure.

English Ivy

This ivy is so common around many homes. Chewing on English Ivy can result in a long list of digestive issues for your dog such as vomiting, abdominal pain, and diarrhea as well as hyper salivation.


We have lantana in our yard but located outside the fenced area, so the dogs are never near it unless on leash.

If your dog eats lantana, it can cause digestive upset and even labored breathing.


All part of the lily are toxic but especially the bulbs; watch for low blood pressure, tremors and cardiac arrhythmia if ingested.

Lilies are extremely toxic to cats so keep all parts of the plants away from the feline members of your family. This is one of the most important on the list of poisonous plants for dogs you’ll find on the ASPCA website.

Morning Glory

We all love morning glories, right? Well, not so much if you’re a dog; ingesting this climbing plant can result in everything from tremors to anorexia to hallucinations.


We really have to watch our dogs around the oleander plants that thrive on the Texas coast. Every part of these flowering plants are toxic to dogs (and other animals).

Troubles including difficulty breathing, muscle tremors, and even cardiac failure can result from ingestion.

Sago Palm

Yes, we’re back to the Sago Palm because so many people just don’t realize how deadly the seeds of this plant are to dogs. Ingestion of just one seed can be fatal. All other portions of the sago are toxic to dogs as well.


Tulips are toxic to dogs; in this case, the bulbs of this plant that are the troublemakers. Watch for oral and gastrointestinal irritation, nausea, cardiac impairment, and even convulsions if eaten.

If you think your dog may have eaten one of these plants or another plant poisonous to dogs, call your veterinarian or call ASPCA’s 24-hour emergency pet poison hotline at 1-888-426-4435 (there is a consultation fee for callers).
