Mites
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.
As their name suggests, ear mites inhabit the ear canals and surrounding skin. Ear mite infestations can occur in dogs and cats, but infestation is more common in cats. Signs of infestation typically include skin irritation; scratching around the ears, head and neck; head shaking; the presence of an ear discharge that is dark and waxy (resembling coffee grounds) and an unpleasant odour from the ears. Your vet can diagnose ear mites by looking at a sample from the ear canal under the microscope.
