Canine Worms Dogs are victims of several internal parasites frequently referred to as worms. The most common are the roundworms that infest most puppies at some time in their young lives and tapeworms that can be a big problem when flea infestations are high. Evidence of roundworms and tapeworms can be seen without the aid of a microscope, but other worms are not so easily diagnosed. Occasionally adult whipworms can be seen in the stool when the infestation has already caused some debilitation or weight loss in the dog. Early diagnosis of the presence and species of intestinal parasite is important, for not all worms respond to the same treatment. Therefore, stool samples should be taken to the veterinarian for microscopic examination if worms are suspected. Many veterinarians include the stool check as part of the annual health examination. Most worm infestations cause any or all of these symptoms: diarrhea, perhaps with blood in the stool; weight loss; dry hair; general poor appearance; and vomiting, perhaps with worms in the vomit. However, some infestations cause few or no symptoms; in fact some worm eggs or larvae can be dormant in the dog's body and activated only in times of stress, or in the case of roundworms, until the latter stages of pregnancy, when they activate and infest the soon-to-be-born puppies.
