Many types of plants and flowers can be poisonous to your dog. Effects range from mild to severe depending on the type of plant and the quantity consumed. Some plants will only cause slight stomach upset, while others can cause seizures, coma or even death. Learn about the plants in your yard and neighborhood that are dangerous and be sure your dog does not have access to them. Ideally, toxic plants on your own property should be removed.

Houseplants are a bit easier to control - simply do not keep toxic plants inside your home and you have removed the risk. If you are planning to get new plants or flowers, research them ahead of time to learn whether or not they are toxic.

Find out what plants and flowers may be poisonous to dogs with the following list of common toxic plants and flowers. Please note that this is not a complete list. If you have a particular plant in mind for your home or yard, you should thoroughly research it first. If you suspect your pet has come into contact with a potential toxin, please contact your vet or animal poison control immediately.
