There are a lot of plants that are toxic to dogs. Dogs tend to explore the world with their mouths and so can easily be at risk of licking, chewing, or eating a poisonous plant. Some dogs are more curious than others, especially puppies and young dogs, which means you need to be extra careful to keep your furry friend safe.

While not all plants considered toxic are life-threatening, keeping your eyes on your dog is still important. Consumption of any unhealthy plant can cause an upset stomach and other issues. While the symptoms may be mild and not life-threatening, they can be uncomfortable for your pet.
