When dogs ingest whipworm eggs from a contaminated environment, they can become infected with whipworms (Trichuris vulpis). Many whipworm infections in dogs may not have obvious clinical signs, but you may notice:1
Mucus in stool
Even death in severe cases
Stages of the whipworm lifecycle in dogs
Inside the dog’s large intestine, adult whipworms live and release eggs.
Eggs are released in feces 74-90 days after infection.
Eggs contaminate the soil in your yard, where they may persist for years.
Invisible to the naked eye, larvae develop in the eggs and become infective in 9-21 days.
Contaminated soil on toys or dog’s paws may put the dog at risk of infection if embryonated eggs are ingested.
After ingestion, larvae hatch from eggs and are released into the gastrointestinal (GI) tract, penetrate the intestinal wall, develop for 2–10 days, and then move to the cecum where they mature into adults.
Treatment with fewer than 6 monthly doses after the last exposure to mosquitoes may not provide complete heartworm prevention. Prior to administration of Interceptor® Plus (milbemycin oxime/praziquantel), dogs should be tested for existing heartworm infections. The safety of Interceptor® Plus has not been evaluated in dogs used for breeding or in lactating females. The following adverse reactions have been reported in dogs after administration of milbemycin oxime or praziquantel: vomiting, diarrhea, depression/lethargy, ataxia, anorexia, convulsions, weakness, and salivation.
