Rhododendron and azaleas can be harmful to an animal's heart, intestines, and nervous system. Philodendron and dieffenbachia are common houseplants which can prove fatal. And even leaves and stems from tomato plants can be harmful. It's best to keep pets out of vegetable and flower gardens altogether, but if you suspect your pet may have eaten a poisonous plant, watch for symptoms such as vomiting, diarrhea, loss of appetite, mouth swelling, and salivation. Take the animal to your vet and take along a leaf from the plant that was eaten.
Treatment is based on the type of plant and amount swallowed.
Be prepared to take care of your pet in an emergency. Create a portable pet disaster supply kit. Avoid bites by keeping your pet on a leash and by your side while in the woods, and staying on trails in wilderness areas. But if your pet gets bitten, don't panic. Try to determine if the bite came from a poisonous snake, taking care not to get bitten yourself.
