Try to keep your dog from coming in contact with intermediate hosts that contain tapeworm larvae. How do I prevent my dog from getting tapeworms? Contrary to popular belief, dogs that “scoot” on their rear ends are generally doing it for reasons other than having tapeworms, such as blocked or irritated anal sacs (pouches located in your dog’s rear end) or other skin inflammation of the rear. Dipylidium caninum is a tapeworm that uses fleas as its intermediate host, whereas Taenia and Echinococcus species use small rodents (mice, rats, squirrels), rabbits, or large animals (such as deer or sheep) as their intermediate hosts.ĭogs with tapeworm infections usually are not sick and do not lose weight from the worms.

There are several different kinds, or species, of tapeworms that can infect your dog, each with stage(s) in a different intermediate (in-between) host, which the dog eats to become infected. Tapeworm infections are usually diagnosed by finding segments-which appear as small white worms that may look like grains of rice or seeds-on the rear end of your dog, in your dog’s feces, or where your dog lives and sleeps. A tapeworm body consists of multiple parts, or segments, each with its own reproductive organs. Tapeworms are long, flat worms that attach themselves to your dog’s (or cat's) intestines.
