Whipworms: Tiny, yet hardy.

Whipworms are often found in dogs, and spread when infected animals pass the eggs through their stool. But these are no ordinary eggs: they can survive up to 5 years before finding a host and maturing further!

Once inside your pet, whipworms hatch, mature and complete their lifecycle in your dog’s intestinal tract, using your pet as their food source. The good news is that whipworm infections can be treated with a dewormer. But because whipworm eggs remain in contaminated areas for a long time, preventing reinfection requires vigilance. You can help by keeping pet areas clean, regularly removing pet waste in your yard. The use of heartworm preventives that also treat and control whipworms has led to a decline in infections.1

Whipworms are found throughout the United States infecting dogs from coast to coast.

What do whipworms look like?
