Common Household Plants That Are Toxic To Dogs

As a pet owner, it’s critical to be aware of some of the most common household plants that are toxic to dogs. If your curious dog ingests these plants, symptoms may range from vomiting, to extreme illness and in some unfortunate cases, death.

If you suspect that your dog has consumed a poisonous plant, take it to the vet right away.

Here is a list of some common household plants that you should keep away from your dog:

1. Sago Palm
All parts of the Sago Palm are extremely poisonous, in particular, the seeds. The seeds are the most toxic and much easier to ingest. If left untreated serious issues could occur such as neurological issues and liver failure.

2. Lilies
It is widely known that Lilies may cause fatalities with cats, however, it is not as commonly understood that certain lilies are also toxic to dogs. Dogs can be poisoned if they consume any plant from the Lilium genus, commonly known as "true lilies.". These lilies are hazardous due to the presence of alkaloids, which can harm red blood cells.

3. Oleander
Any part of the oleander plant can poison dogs, particularly the roots and stems which are the most toxic. Oleander contains cardiac glycosides that can affect the electrolytes in the body and raise potassium levels, potentially causing life-threatening heart arrhythmias.

4. Aloe Vera
Aloe vera contains anthraquinone glycosides, which are powerful laxatives. Aloe vera also contains saponins which are extremely toxic to dogs.

5. Devil’s Ivy
The stems and leaves of Devil's Ivy are hazardous to dogs, as they contain insoluble calcium oxalate crystals. These crystals can cause harm when a dog bites into or chews the plant, as they can penetrate the oral and digestive system tissues.

6. Autumn Crocus
Autumn Crocus is extremely toxic to dogs, it contains colchicine which will cause gastrointestinal distress and potentially death if left untreated. All parts of the Autumn Crocus are toxic to dogs.

7. Azaleas
Azaleas contain grayanotoxin, a toxic compound that interferes with sodium channels and impacts the muscles in the skeleton and heart. Even a small amount of ingestion, equal to 0.2% of an animal's body weight, can lead to poisoning.

8. Cyclamen
All of the cyclamen plant is poisonous to dogs, particularly the tubes and roots. Cyclamen contains irritating saponins which can cause serious toxic reactions in dogs.

9. Tulips
Tulip bulbs are the most toxic part of the plant, where the highest level of toxic alkaloids is found. However, it is best to keep the entire plant away from dogs as glycosides appear in all parts of the plant.
