Plants Toxic to Dogs, Flowers

Plants Toxic to DogsThere are a lot of plants toxic to dogs as well as flowers. Some of them may be a mild toxicity and some more severe. We always like to suggest going with the side of caution and avoiding all on our list. As dog owners we have all seen our furry friends liking to chew on the house plants or some vegetation outside. Perhaps take a closer look at this list and see if your plants are on it. We will be adding to the list as time goes on.

As a disclaimer, this list may not be complete and pet owners should always do their own research before allowing their pet to eat any plants or flowers or vegetation. This is a general information article only and does not provide medical opinion in any way.
