Raising Awareness About Tapeworms and Whipworms in Pets

Despite the effective treatments available, a study from 2013 to 2016 showed that two-thirds of dogs in the U.S. did not receive heartworm prevention. In 2016, only 35.69% of dogs were treated with preventive products, highlighting a gap in care that could be improved.

Changes in a pet's behavior, energy level, or appetite often prompt owners to contact veterinary offices. However, many internal parasites are difficult to detect since adult worms are rarely visible and eggs and larvae are microscopic. According to Steve Milden, VMD, many owners mistakenly believe their pets are parasite-free based solely on the appearance of their stool. In reality, many infections are subclinical, meaning symptoms are not always present.

Tapeworms are a common internal parasite, particularly Dipylidium caninum. The Companion Animal Parasite Council (CAPC) notes that reported prevalence rates for this parasite in dogs range from 4% to 60%. This discrepancy arises because fecal flotation methods likely underestimate actual infection rates, as tapeworm eggs are heavy and often do not float. In a 2017 study, only 4.2% of shelter dogs tested positive for D. caninum using fecal flotation, whereas necropsy revealed a rate of 46.4%.

Infection with tapeworms occurs when dogs ingest flea larvae that harbor the infectious cysticeroid form of the parasite. Signs of a tapeworm infection are typically minimal, but visible proglottids can be alarming to pet owners. Key education for clients should emphasize the importance of flea control and the potential for human infection through the ingestion of infected fleas.

Whipworms, specifically Trichuris vulpis, are also a concern for pet dogs and can be found across the United States, with a notable infection rate of near 2% in places like West Virginia. Research indicates that whipworm infections were found in up to 14.3% of shelter dogs and 10% of those in veterinary teaching hospitals. Dogs become infected by swallowing eggs present in the environment. The adult worms reside in the cecum and can lead to symptoms such as dehydration and bloody diarrhea.

Whipworm eggs are difficult to eliminate, persisting in the soil for years, which poses a continuous infection risk. Thus, year-round parasite prevention is crucial. Key client education should inform pet owners that whipworms can cause significant gastrointestinal issues and that their eggs are resilient.

Veterinary staff can utilize effective treatments such as Sentinel® Spectrum® Chews, which provide comprehensive protection against multiple parasites, including tapeworms and whipworms. These monthly chews can be given to puppies as young as six weeks, making them a central part of preventive care.

Despite the availability of these products, there is often a need for ongoing education to ensure pet owners prioritize parasite prevention. Regular communication through various channels can help reinforce the importance of protecting pets from these hidden threats.
