Most of us don’t think twice when bringing a new plant into our garden or home. However, many houseplants and common yard plants are poisonous to our pups, so it’s wise to double-check if a plant is poisonous before you’ve planted it or brought it into your home. Today, we’re going over some of the most common poisonous plants to dogs in our A to Z Guide.
While we’re at it, let’s take a moment to clarify what the difference is between toxic and poisonous plants. These words are typically used interchangeably because they are similar but not quite the same.
Toxic refers to the degree of harmful components. In contrast, poisonous describes plants that will likely cause harm to an animal if they are consumed or come into contact with the animal. Often, a poisonous plant has a high level of toxicity because poison heavily implies that a substance contains a high level of toxicity. However, please keep in mind that any substance can be poisonous if consumed in high quantities.
