What to do if your dog ingests a Toxic Plant

If you think your dog has eaten something harmful, take these steps:

  • Contact your vet, AKC Vetline, or the Pet Poison Helpline (855-764-7661) for accurate advice.
  • Try to figure out what the dog ate by collecting a sample, taking a photo, or saving the vomit in a plastic bag.
  • When you talk to the vet or helpline, provide as much information as possible, including the suspected plant, when it happened, your dog’s weight, and any symptoms they’re showing.

Plants that are Safe for Dogs

It’s not easy to make a list of plants that are completely safe for dogs. Even though we know some plants are harmful, it’s hard to guarantee that a plant won’t cause problems if your pet eats or chews it. Identifying plant species can be tough, and most plants can be troublesome if your pet consumes a lot of them.

To be on the safe side, it’s best to keep all indoor plants out of your pet’s reach so they don’t try to eat or nibble on them when you’re away. Also, keep an eye on your dog when they’re in the garden or on walks to make sure they haven’t come across any plants that could be harmful to them.
