When Good Dogs Eat
Bad Plants |

The incidence of plant poisonings in dogs goes up every summer, says Larissa Hautekeete, D.V.M., of the American Society for the Prevention of Cruelty to Animals (ASPCA’s) National Animal Poison Control Center (NAPCC), a nonprofit 24-hour emergency consulting service. Usually the problem is that dogs get bored and decide to nibble on plants. Certain ornamental plants and shrubs, such as rhododendrons and Dieffenbachia (known as dumb cane), are particularly toxic. If you have these plants in your yard or in your house, it’s best to keep your dog away from them. Nibbling on grass, which some dogs like to do, can become problematic when the lawn has been treated with chemicals. In fact, Fred Oehme, D.V.M., Ph.D., professor of toxicology at Kansas State University in Manhattan, Kansas, says plant poisonings of dogs are far less common than poisonings with pesticides, rodenticides and rotten garbage. (Toxicologists point out that dogs can become sick from the same plants that are toxic to cats.) In Case of Emergency If your dog ingests part of a poisonous plant, call your vet immediately. Under veterinary advice, you may need to induce vomiting, using either 3 percent hydrogen peroxide (1 Tablespoonful for a 30-pound dog; can repeat twice) or ipecac (1 to 2 milliliters per kilogram of body weight, which is 3 to 5 teaspoons for a 30-pound dog). Your veterinarian can give an injection that will induce vomiting in a matter of minutes. This may be the best solution, especially if you have trouble getting your dog to take whatever medicines you administer. If your veterinarian is unsure about the toxicity of the plant ingested, you or the doctor may have to phone your local poison control center or the NAPCC, which can be reached 24 hours a day, seven days a week at 1-888-4ANIHELP or 1-800-548-2423 (to charge the $30 consulting fee to your credit card; you can also opt to charge the call to your phone bill by calling 1-900-680-0000). Be sure to keep the tags from any plants you buy—you may need to supply the Latin name as well as the common name to the consulting veterinary toxicologist. The NAPCC advises dog owners who suspect their pet has been
poisoned by a plant to remain calm and to have as much information on
hand as possible before making the emergency call. When you call
the NAPCC be ready to provide: The NAPCC publishes a list of household plants that are toxic, potentially toxic and nontoxic to animals, available for $15 (shipping and handling included). Send your name, address and check to: ASPCA National Animal Poison Control Center, 1717 South Philo Road, Suite 36, Urbana, IL 61802.
