Following is a lists of indoor plants known to be toxic to dogs.

Remember the first principle of toxicology, which is that “the dose makes the poison.” In other words, the dog has to eat enough to be affected—and even so, many poisonous plants don’t kill, they just sicken.

How much is too much? The ASPCA's Animal Poison Control Center (888 426-4435; $65) or the Pet Poison Helpline (800 213-6680; $35) can help you figure that out.

Finally, for Animal Poison Control (or your vet) to help, they have to know what exactly your dog ate. “A tall green plant with spiky leaves” isn’t a good answer. If you have pets or kids, know your houseplants by both common and botanical names, which usually come on a tag with the plant. Keep that info where you can find it.

This lists isn't comprehensive—no list is—but it covers the most common plants your dog might encounter indoors.
