Trichuris vulpis is a whipworm parasitizingon dogs and occurring worldwide. The whipworm infestation only leads to mild to moderate diarrhea in the host.
Like all whipworms, T. vulpis has a long, thin front end and a thickened rear end. Male worms are 4.8-5.6 cm long and have a spiculum about 1 cm long . Females are 6.5–7 cm long and the vulvar region is covered with thorns.
The eggs are lemon-shaped, 80 × 40 µm in size, brownish, thick-skinned and have thickenings ("pole pods") at the poles. They are not fearful when they lay their eggs. Infection occurs through ingestion of the eggs embryonating in the outside world (containing larva I). They slip in the duodenum and jejunum and penetrate their mucous membrane. After about 10 days they colonize the appendix and colon . The prepatency is relatively long at 9-10 weeks.
