1Over-the-Counter Medications

2Human Prescription Medications

3Food
Westend61//Getty ImagesIf you're known to give your pup tons of people food, think twice. Common ingredients like grapes, raisins, onions, and garlic are toxic to pets. If you have a dog, watch out for the sweetener xylitol found in candy, gum, baked goods, and even toothpaste. "Xylitol is probably the most dangerous because it can drop their blood sugar and cause liver failure," Dr. Wismer says. And of course, alcohol is always a no-go.
4Chocolate
Diana Miller//Getty ImagesChocolate gets its own special entry, because when combined with other foods it would probably top the list every single year, Dr. Wismer says. The APCC gets nearly 60 cases related to cocoa every single day! The toxicity depends on the size of animal and the darkness of the chocolate. For a 20-pound dog, it would take 16 ounces of milk chocolate, 9 ounces of dark chocolate, or only 1.5 ounces of baking chocolate to cause seizures.

5Veterinary Products
EHStock//Getty ImagesWhile prescribed medicines are safe to use as directed, make sure you're carefully monitoring the dose — and keeping the supply out of paws' reach. "What we've done to make it easy to give dogs pills is make them chewable and flavored, which also means it's also really easy for a dog to eat his entire bottle of pills," Dr. Wismer explains.
6Household Items

7Rodenticides

8Insecticides

9Plants
ivstiv//Getty ImagesThey're pretty to look at, but many common flowers and plants are poisonous to cats and dogs. The sago palm, for example, is a popular perennial in the Southern U.S. and houseplant everywhere, but the toxic leaves, trunk, and especially the seeds can cause liver failure in dogs. Cat owners, watch out for lilies in Easter and Mother's Day flowers. They can cause kidney failure if ingested.
10Garden Products

11Marijuana
Norman Posselt//Getty ImagesWhile it didn't make the official list, Dr. Wismer notes that the APCC is getting a growing number of calls about marijuana (newly legal in an increasing number of states) and CBD products, especially edibles. "Many times these are products that are highly concentrated and also contain chocolate, so dogs find them very tasty," she says. The concentrated THC can lead to low blood pressure, comas, and even death.
