Whipworms are parasites that infect a dog's intestines. Dogs pick up these parasites when they ingest infected feces, food and water. Symptoms of a whipworm infection include diarrhea, often with blood or mucus, dehydration, anemia and weight loss. If your veterinarian suspects whipworm, a stool sample confirms their presence and treatment will begin.
Various medications treat whipworm infestations. Common parasiticides for treatment are fenbendazole and mebendazole; common brands of such medicines include Panacur, Drontal Plus, Telmintic and Vercom Paste. It can take numerous treatments to eradicate whipworms. Typically, treatment includes an initial worming treatment followed by additional treatments at intervals of three weeks and three months.
If your yard has frequent canine visitors who leave presents, regular poop-scooping will help reduce the risk of your dog contracting whipworms from infected feces. Use caution at public parks and dog parks, keeping your dog away from feces. If your dog takes year-round heartworm prevention medications, the drugs Interceptor and Sentinel offer whipworm prevention as well.
