Dog Biting Louse

A chewing louse that infests domestic dogs, feeding on skin debris and secretions. It can serve as an intermediate host for the dog tapeworm.

💡

Did You Know?

Dogs can acquire tapeworm infections by accidentally swallowing these lice during grooming, as the lice carry tapeworm larvae.

Pubic Louse

A broad, crab-shaped louse that infests coarse body hair, primarily in the pubic region. It is transmitted through intimate contact.

💡

Did You Know?

Pubic lice are more closely related to gorilla lice than to human head lice, suggesting an ancient host-switching event between primate species.
