A List of Common Plants That are Toxic and Can Make Dogs Sick

House plants toxic to dogs
We maybe blissfully unaware of it, but our dogs are at a risk of being poisoned by some common houseplants that we unsuspectingly keep. To prevent an accident, take a look at the list of plants mentioned here, and keep them away from your dogs.
Warning!
Common symptoms of poisoning are vomiting and diarrhea. If you spot these in your dog for no apparent reason, rush to the vet without wasting a moment.
Curious creatures that they are, dogs are habituated to inspecting everything around them. Bored dogs, especially, are quite capable of making chew toys out of anything, including plants, which makes them susceptible to poisoning, and which, at times, may even result in death.

Unfortunately, there is quite a long list of plants and parts of certain plants that are toxic to dogs. Included in the list are several flowering plants and shrubs that are kept within most homes as a means of decoration.

From lilies to buttercups and morning daisies, danger lurks everywhere for pets. Chances that your dog will be making a meal out of some of these plants is a distinct possibility. Therefore, it is recommended that such plants be kept out of the dog's path.
