Sarcoptes mites not only affect dogs, but can also be transmitted to humans. The mites easily pass from an infested dog to other dogs that are in close contact. Sarcoptes mites burrow into the skin, leading to intense itching, hair loss, and skin infections. Confirming a diagnosis of Sarcoptes mites can be difficult as the mites live within the skin.
Your vet may need to examine a skin scraping under the microscope to identify the mites.
