The whipworm lifecycle in dogs

Whipworms (Trichuris vulpis) are something to hope you never have to deal with. But if your dog gets infected with these dangerous parasites, learning about the canine whipworm lifecycle can help you understand what’s going on and what your veterinarian may be doing to treat the infection.

Whipworm lifecycle1

Whipworm eggs pass into the environment through feces of infected dogs. Once deposited in the soil, they are highly resistant to desiccation by environmental factors such as temperature extremes and sunlight and can remain viable for years.

Infection occurs when a dog ingests the infective eggs. The larvae generally hatch in the small intestine and then move to the large intestine, where they mature into adult worms in 74-90 days.

Treating whipworm infection in dogs

You should always start by talking to your veterinarian, who can answer all of your questions and recommend a treatment plan with a product like Trifexis® (spinosad + milbemycin oxime) that controls whipworm infections. Trifexis is the once-monthly, beef-flavored tablet that kills fleas, prevents heartworm disease and treats and controls adult hookworm*, roundworm and whipworm infections. Trifexis is approved for use in dogs and puppies 8 weeks of age and older and weigh 5 pounds or greater.
