October 2010 My Pet Ate What? - Toxicities

By Christopher Weisner, DVM Emergency, Trauma, and Critical Care Department

Should you induce vomiting in my dog or cat and how would I do it?

If your pet (dog or cat) has recently ingested a suspected toxin, it is very important to contact a veterinarian or Animal Poison Control (888- 426- 4435). There are some circumstances when inducing vomiting is contraindicated. Vomiting should never be induced if an acid or strong base has been ingested such as chewed batteries, if a caustic agent (damaging to tissues) is ingested such as potpourri oils, or if an object may become stuck in the esophagus when vomited, such as a chicken bone. It is always advisable to contact a veterinarian before inducing vomiting to ensure that it is a safe choice.

There are many toxicities in which inducing vomiting is appropriate. All pill medications, chocolate, and xylitol containing gum are some examples. Hydrogen peroxide is one of the most effective methods for inducing vomiting in dogs and cats. The hydrogen peroxide must be fresh and still bubble when poured. An appropriate dose for a cat and a small dog is about 1-2 teaspoons. A medium size dog could be given 1- 2 tablespoons, and a large size dog could be given 3 tablespoons of hydrogen peroxide. If there is no vomiting in 10 minutes it is OK to repeat the dose.
