Before you bring home a new dog, you’ll want to evaluate what plants you have both inside of your home and out. Dogs are known for chewing on and eating things they shouldn’t, and the last thing you want is an emergency trip to the vet.
Here's a list of plants that are toxic to dogs, organized by type for easier reference. We’ve also linked to the ASPCA Poison Control Center info on each plant so you can see a photo and additional information for reference.
DISCLAIMER: This is NOT a comprehensive list of all plants that are toxic to dogs. These are some of the most common ones you may encounter. For a full list of 415 toxic plants, please visit ASPCA Animal Poison Control.

What To Do if Your Dog Eats a Toxic Plant
If your dog eats a toxic plant, don’t panic, but do move quickly. Time can be of the essence, depending on what they ate.
Calmly do the following:
Identify the plant (a photo can help).
Call your veterinarian immediately.
Contact ASPCA Animal Poison Control at (888) 426-4435 (available 24/7 – fees may apply).
Do not induce vomiting unless directed by a professional.
Transport your dog to the closest veterinarian or emergency vet.
Final Thoughts
Dogs and plants can exist under the same roof (or in the same yard). However, it’s important to make sure that the plants you bring into your dog’s living space are not toxic.
While that will limit your plant options, your dog will undoubtedly give you more love and joy than a plant ever could. So, get rid of any plants that may pose a danger to your dog.
Then, you can enjoy the peace of mind that comes with sharing a safe home and yard with your pup!
