Canine Hookworm Eggs

Description:

Microscopic eggs are translucent with a thin shell. They are excreted in the feces of infected pets. Once in the environment, they can infect other hosts either by ingestion or through the skin (larval stage). Puppies can acquire infection from their mothers while nursing as the larvae can pass through milk and colostrum. Pets infected with hookworms can suffer from weight loss, anemia (which can be very severe), lethargy, along with some other symptoms.

Habitat:

These eggs were found in the feces of an affected puppy. Adult worms generally live in the small intestines of dogs. In larval stages, this nematode can be free living and survives well in temperate, tropical and sub-tropical climates (see Wikipedia).
