Causes of canine whipworm:

1. Trichocephala vulgaris is milky white. The front part is slender and filamentous, which is the esophagus, accounting for about 2/3 of the total length of the worm. The rear part is the body, short and thick. The body length of the insect is 45-75 mm, the rear part of the female insect is blunt and straight, and the tail end of the male insect is curled.

2. The eggs excreted in the feces will develop into infectious eggs in about 3 weeks under suitable conditions. After a dog ingests infective eggs, the larvae hatch in the intestine, burrow into the mucosa of the front of the small intestine, stay for 2 to 10 days, and then enter the cecum to develop into adult worms.

Clinical symptoms of canine whipworm:

1. Generally, infection does not show clinical symptoms.

2. In severe infection, acute or chronic enteritis can occur because the head of the parasite burrows deeply into the mucous membrane.

3. Blood-sucking worms often cause anemia in sick dogs.
