Symptoms of Whipworm in Dogs & Treatment Options

If your dog is experiencing symptoms such as diarrhea and weight loss whipworm could be the issue. In today's post, our Greensboro vets discuss whipworm, what it is and how to protect your dog against this common parasite.

How to Identify Whipworm in Dogs

Whipworms (scientific name Trichuris vulpis) are intestinal parasites that can seriously impact your dog's overall health. Measuring about 1/4 of an inch long, these parasites make their home in your dog's large intestine and cecum where they attach to the mucosal lining causing extensive irritation.

This intestinal parasite can be easily identified by their shape. They have a thicker front end and long thin back end that look much like a whip. 

Whipworm Lifecycle in Dogs

There are 3 stages to the lifecycle of a whipworm, egg, larvae and adult. The eggs are laid in the dog's intestine where they are incorporated into the dog's stool. This means that an infected dog spreads whipworm eggs each time they have a bowel movement. The eggs are extremely resilient and able to remain alive in the environment for up to 5 years.

Once out in the world, the eggs typically mature into the infective stage in about 10-60 days, at which point they are ready to infect the next host animal.  Soon after they are ingested they hatch and mature in the pet's intestine where they lay more eggs and begin the cycle once again.

Signs That Your Dog May Have Whipworm

If your dog has recently become infected there will likely be few signs of a whipworm infection, and even in the later stages of infection, some dogs will remain asymptomatic (show no symptoms). That said, some of the most common whipworm symptoms in dogs include:

  • Chronic diarrhea
  • Weight loss
  • Blood in stool
  • Anemia

Diagnosing Whipworm

Fecal exams at your vet's office are the best way to monitor your dog for intestinal parasites including whipworms. Whipworms take up to 12 weeks to mature and begin laying eggs, and tend to lay limited numbers of eggs and on an inconsistent basis. For these reasons, diagnosis can be tricky and may require repeated fecal exams to reach an accurate diagnosis. 

Whipworm In Dogs Treatment

Whipworm eggs are incredibly resilient, making reinfection a real issue. The truth is that whipworm can be a challenging parasite to get rid of.

Whipworm treatment for dogs consists of prescription medications to kill the parasites living within your dog's intestine, and if necessary, further medications to treat any uncomfortable symptoms your dog may be experiencing. Most medications to treat whipworm in dogs will require two treatments spaced about 3-4 weeks apart. To help prevent reinfection it will be necessary to thoroughly clean your dog's bedding, kennel area, and dog run. Your vet may also recommend re-treating your dog every 3-4 months to help fight reinfections. 

Protecting Your Dog Against Whipworm

Our vets firmly believe that prevention is usually far easier and more effective than treatment. Many heartworm medications for dogs also protect against whipworms. By providing your pet with monthly heartworm medication you could also be helping to protect your pet against a host of intestinal parasites including whipworms, hookworms and roundworms. Speak to your vet for information on how best to protect your beloved pup.

At Guilford-Jamestown Veterinary Hospital we also offer a selection of prevention products to help protect your dog against intestinal parasites.
