What Plants are Dangerous for Pets?

As a dog owner, it is easy to think that the only worries you should have are feeding your dog and keeping him out of the toilet. Unfortunately, there are many other potential dangers that pet owners should be aware of. Most dog owners figure the common threats out pretty quickly.

However, there is one hazard that the pet owner easily overlooks. Since dogs live and scavenge outdoors in the wild, it is easy to miss the fact that many plants are poisonous to dogs.

This is especially true when you consider the number of plants moved from their original origin to other parts of the world. The good news is that understanding the most common dangerous plants for dogs is the best way to protect your furry friend.

House Plants

The notion that house plants could potentially be dangerous to your beloved pet might come as a shock. The good news is that moving house plants out of reach is an easy solution to a potentially deadly problem for most people.

Aloe Vera

Aloe Vera is a trendy plant in homes around the US. This plant is known for its healing properties and soothing qualities. Unfortunately, when ingested by a dog, Aloe Vera has a much less positive effect. If ingested by your dog, Aloe Vera can cause significant digestive issues and, in some cases, can suppress the central nervous system.

Dumb Cane

Dumb Cane, or Dieffenbachia as known scientifically, is another common house plant that is poisonous to dogs and cats. This house plant is a larger plant that is likely hard to put on a shelf or counter, making it even more accessible to dogs. Dumb Cane can cause burning in the mouth or throat if ingested by dogs, and in extreme cases, it can cause death.

Check here some house plants that are completely safe for animals.

Outdoor Plants

Sago Palm

An extremely popular plant for landscaping, the Sago Palm is one of the few plants rumored to be tempting to dogs. Unfortunately, the Sago Palm has been proven to cause liver damage when ingested by canines. In extreme situations, the Sago Palm can also lead to death. These plants are very popular in warm locations, so be wary of free-range dogs if Sago Palms are commonly planted in your area.

Tomato Plant

One of the most common vegetables grown in backyard gardens is the tomato plant. Although not known to be particularly deadly, the tomato plant is not considered safe for dogs to ingest. When ingested, the tomato plant can cause disorientation, bradycardia, and dilated pupils in dogs.


Milkweed is another common plant that is grown in yards all around. Milkweed is a colorful plant that is easy to maintain and therefore very common. However, it is highly toxic to your pets. When ingested, milkweed can cause extreme adverse reactions. These include vomiting, diarrhea, respiratory distress, and a weak pulse. Like many other plants, in severe cases, milkweed can cause death in dogs.

Final Thoughts

Although most dogs will avoid eating plants when adequately fed quality food, it is still a good idea to be aware of the vegetation around you.

Understanding the potential hazards in your home and neighborhood can help you to prepare for any likely ingestion that could occur.

Further, being aware of the warning signs related to plant ingestion can help you keep an eye out for signs of an upcoming medical issue. Besides plants, also some human food like onions can be deadly for dogs.
