Plants and pets aren’t always a perfect combination. A surprising number of plants, including landscape and houseplant favorites, are toxic and even lethal if Rover or Fluffy decides they’re edible. Below are just a few of the more than 300 plants that can cause problems. Talk to your vet or visit a poison control website for a complete list.

This isn’t to say that these plants and your pets can’t coexist. Many dogs and cats won’t give these plants a second look. And even if they do get into them, the toxins may not bother them. I’m personally acquainted with a dog who dug up and ate daffodil bulbs, the most poisonous part of the plant, and didn’t even suffer a stomachache.

Still, it’s better to be safe than sorry. Keep an eye on your pets and their chewing preferences, especially puppies and kittens who can, and will, chew on everything. Try using bitter apple or bitter orange spray to discourage leaf chomping, installing decorative fencing or wrapping netting around larger specimens, and placing houseplants out of reach. And if you suspect you pet has gotten into something it shouldn’t have, contact your vet or an emergency clinic right away.

Keep in mind that some of these same plants are also toxic to humans. While adults generally don’t chomp their way through a nonedible garden, it’s wise to keep an eye on small children, especially if they explore the world by putting everything in their mouths.

Azaleas as well as other rhododendron species can lead to vomiting, diarrhea, general weakness and, if the dose is strong enough, even death.
