Some 'people' food can be toxic for petsWhile pet owners munch of a variety of fruits and vegetables as part of a healthy diet, some of these foods can be toxic to their pets. According to the ASPCA's Poison Control Center, the amount of grapes or raisins consumed by a pet that causes toxicity varies from a pound of grapes to just a single serving of raisins, said Dr. Carolynn MacAllister, Oklahoma State University Cooperative Extension Service veterinarian. "Grapes that cause toxicity are those that are purchased at the grocery store, as well as home grown grapes from a vineyard," MacAllister said. "Currently, the toxic substance in raisins and grapes isn't known. However, clinical signs of grape or raisin toxicity may include vomiting and hyperactive behavior. These signs may show up soon after consumption or up to 24 hours later." As the toxicity progresses, dogs tend to stop eating. Pet owners also may observe diarrhea along with lethargy and abdominal pain. If left untreated the animal can go into acute kidney failure, and as the condition worsens, the affected animal may stop drinking and urinating. "If the affected pet does not receive appropriate and timely veterinary care, grape or raisin toxicity can be fatal," she said. Fortunately, dogs that have ingested grapes or raisins can usually be successfully treated to prevent the development of acute renal failure as long as treatment is administered quickly. Xylitol, a sweetener used in sugar-free gum, candy, baked goods, candy and toothpaste can be toxic to dogs. Even though xylitol is not a problem for people, in dogs it causes a sudden and significant insulin release. This increase in insulin results in lowered blood sugar levels. Clinical signs of xylitol poisoning may include vomiting, weakness, collapse, loss of coordination, seizures, and in come cases, xylitol consumption can be fatal. "Recent clinical reports have suggested that xylitol ingestion may be linked to possible liver damage and bleeding problems in dogs," she said. "It's important to keep all products containing xylitol in a sealed container away from your pets." Chocolate is a human food that dogs actually enjoy, but consumption of this treat can cause vomiting, depression, diarrhea, hyperactivity and muscle tremors. A dog can easily consume enough chocolate that results in a lethal toxicosis. "The toxic compound in chocolate is theobromide. A lethal dose varies according to the type of chocolate and the size of the dog," MacAllister said. "Baking chocolate has the highest concentration of theobromide and dark chocolate is more toxic than milk chocolate. The smaller the dog, the less chocolate consumption it takes to be a fatal dose." Pet owners who suspect their pet has ingested any of these foods are encouraged to call their veterinarian or the ASPCA Animal Poison Control Center at 888-426-4435. 5/5/08 Date: 4/29/08 Advertisement
