Whipworms in Dogs (Trichuris Vulpis)

Overview of Whipworms in Dogs

Whipworms are a common parasite in dogs. Scientifically, whipworms are known as Trichuris vulpis. A nematode that feed on blood, they are found in the intestinal tract of dogs and other wild canids. The worms attach to and feed on the canine intestinal wall, often causing watery and sometimes bloody diarrhea.

The most common victims of whipworms are dogs and other canids such as foxes and coyotes. The parasites are transferred through direct contact with an infected animal or the ingestion of an embryonated egg in contaminated feces or soil.

Transmission to humans is very rare and whipworms are not considered zoonotic (contagious between people and animals). Proper hand washing techniques is always advised for anyone that has or thinks they may have come into contact with an infected pet.

Veterinary Care For Canine Whipworms

Care from your personal veterinarian should be sought out for diagnostic testing and treatment. Home care is not advised.

Diagnosis of Canine Whipworms

You will not be able to see whipworms in your pet’s stool with the naked eye. Bringing a small fecal sample into your veterinarian and having them perform a zinc sulfate fecal float is the best means of diagnosis.

Treatment of Canine Whipworms

There are many whipworm treatments including one or more of the following medications:

• Strongid (pyrantel palemoate) – most often given once with a repeated dose in 2 weeks
• Sentinel
• Panacur (fenbendazole) – most often given once a day for 3 days
• Drontal Plus
• Trifexis
• Advantage Multi

Some treatments may be chosen over others based on concurrent parasite infections.

Home Care for Dogs with Whipworms

There are many things you can do at home to keep your dog protected from whipworms:

• Administer all medications as directed and prescribed by your veterinarian. All of the prescribed medication should be given to be sure that you eliminate the infection completely-don’t stop when symptoms disappear. You should also be sure to treat all infected pets in the household.
• Decontamination of the environment is a very important part of preventing infection. Keep feces picked up from your yard on a regular basis, especially if you have an infected animal. In situations such as kennels, animal shelters, and pet stores, where animals are kept under close confinement, proper sanitation is crucial to prevent cross-contamination from animal to animal. All fecal matter must be removed from cages and yards. Kennels must be cleaned with proper disinfectants, allowed appropriate contact time, and totally dried before pets can come into contact with them. The most common effective disinfectants are bleach and clorhexadine solutions.
• Give all doses of dewormer to ensure that you kill all of the worms living in the intestinal tract.
• Give any prescribed heartworm prevention medications that may also treat whipworm infections.
