Chorioptes bovis is a recognized cause of dermatitis in cattle, horses, sheep, and goats. C. bovis is transmissible between any of these hosts, but cattle are thought to be the most common disseminators. The mites behave in a similar manner on all these hosts. Classically, the lesions first occur on the posterior fetlocks and pasterns, spreading to many other parts of the body by extension.
