Dog whipworm can pose a serious problem for your dog because, unlike some of the other dog worms, this one literally drinks your dog’s blood.

Whipworms are parasitic nematodes that live in the cecum, the first section of the dog’s large intestine. Whipworm get their name from their whip-like shape.

Whipworm is one of the smaller intestinal worms with a size that ranges from 1.1 - 2.0 inches (30-50 mm) in length. It has a small, narrow anterior head, which is the digestive part of the worm, and a larger posterior tail. This tail is the reproductive part of the whipworm.

The good news is that a dog’s reaction to whipworms will usually be on the mild side, although there are exceptions to this. If your dog becomes heavily infected with whipworms, it can suffer diarrhea and you may notice that its feces is streaked with fresh blood. Young dogs, or dogs that have a chronic infection, can suffer severe weight loss, dehydration due to the diarrhea, and even anemia from blood loss as a result of a whipworm infection.

Dog Whipworm Infection

Dogs must eat whipworm eggs to become infected with whipworms. These worm eggs can be found in prey, dog feces and contaminated water. Whipworm eggs can survive for months or even years and will even resist freezing.

Once inside a dog, whipworm eggs hatch, mature into adult whipworms that live inside the dog’s cecum, colon and rectum. Whipworms burrow into the intestinal wall and begin feeding on the dog’s blood. They reside there for about three months before they begin laying eggs. The adult whipworms lay many eggs that are released in the feces into the outside world. Whipworm eggs are able to form embryos in the soil in about 2-4 weeks, at which time they become infective if ingested by a new host.

Dog Whipworm Symptoms

The symptoms of dog whipworms can include nonspecific diarrhea, weight loss and blood-streaked diarrhea. The difficult thing about a whipworm infection is that while it may show no apparent symptoms, it can cause recurring diarrhea and colitis in dogs.

Dog Whipworm Diagnosis

The only practical way to diagnose whipworms in a dog is by finding the worms in its stool. Since female whipworms do not produce eggs every day, and the number of eggs they do produce is usually small, it may be necessary to have repeated fecal exams in order to find the eggs and diagnose a whipworm infection.

Preventing Whipworm In Dogs

The best way to keep your dog from becoming whipworm infected it is to keep its area clean and free of feces. You should also make sure that its toys, bones and any other items your dog likes to chew on are clean and free of dirt. The fact is there is no good way to kill whipworm eggs in the soil. If you believe the dirt in your dog’s run or kennel has been whipworm-infected, you will need to replace the soil with new dirt, gravel or pavement. Dog runs and the floors of kennels should be impervious so that they are easier to clean. Kennels, runs and litter boxes need to be cleaned thoroughly and then allowed to dry in direct sunlight if possible. Also, any feces in your yard should be picked up on a daily basis.
