Canine Parasite - Whipworm
Overview - Whipworms are small thread-like parasites that embed deep within the lining of the colon (large intestine) and
cecum. Trichuris vulpis, the canine whipworm, is a common parasite and is a major cause of diarrhea in the dog.
Parasite target - large intestine
Symptoms - Light infections of whipworms are difficult to diagnose, but they can lead to more
serious problems. Large numbers of whipworms irritate the lining of your dog's intestine causing weight loss and pain. Watery and bloody stools may result.
Severe infections can cause life threatening dehydration and anemia. Whipworms are not dangerous to people, but once dogs become infected, whipworms are
difficult to eliminate without medication programs
Treatment - Treatment Whipworm infections can be difficult to treat due to the high incidence of re-infection from
contaminated environments. Eggs, because of their thick shell are very resistant, they can remain in the environment for as long as 5 years , and in
areas where whipworm is prevalent, it is almost impossible to prevent re-infection unless measures are taken to treat the dog most frequented areas.
Even then, the eggs are resistant to most cleaning methods and re-infection is likely. The long (3 month) pre-patent period means
that dewormers given at a 2 to 3 week intervals would not control the immature stages, and treatment for this worm must be long term if there is to be any
chance of success.
Treatment and control for whipworm currently includes Milbemycin Oxime found in both SENTINEL and INTERCEPTOR. Depending on the situation and
environment your dog is in, your veterinarian will be able to prescribe the appropriate medication to treat your dog for these parasites.
It is important to note that all canine dewormers currently available are labeled as being effective only against the adult stage of the worm. Within
weeks or even days of deworming, immature larvae that were present in the gut, but unaffected by the medication, will develop into mature adults and begin
laying eggs again.
Prevention - To prevent exposure, any feces in the yard should be picked up on a daily basis. Routine fecal examinations and
wormings can help control this parasite.

Sentinel Flavor Tabs contain two active ingredients. Milbemycin oxime is thought to interfere with the parasite's nerve transmission,
causing death of both immature heartworms (larvae) and adult intestinal worms. Lufenuron inhibits flea egg development and prevents fleas from
becoming reproducing adults. Lufeneron does not kill adult fleas.
