10 common outdoor plants that are toxic to pets

Warmer weather will soon make its way across Canada, and that means pets -- and their pet owners -- will be spending more time outdoors.

While there's nothing wrong with a little fresh air, here are 10 common outdoor plants you'll want to steer your furry friends away from.

If your pet has ingested a toxic plant or you suspect you pet has come into contact with a poisonous plant, take the animal to a veterinarian immediately. The sooner possible poisoning is identified and treated, the better your pet's chances for a speedy recovery.

10. AZALEA

Ingesting an azalea can cause serious health problems in pets. Eating just a few leaves can lead to vomiting, diarrhea and drooling. If not treated by a veterinarian, an animal could fall into a coma, possibly leading to death.

Some types of lilies -- like the peace, Peruvian and calla lily will do nothing more than irritate the mouth, tongue and esophagus if ingested.

Other types of lilies, like the day (pictured above), day, Asiatic, Easter and Japanese show varieties can result in kidney failure in cats. Between 2 and 3 petals or leaves is enough to cause serious issues.
