Behavioral dermatopathies in small mammals

Several skin conditions seen in small mammals are thought to have a behavioral cause but their epidemiology and pathogenesis are poorly understood. A significant amount of research exists on barbering in mice that suggests it is an impulse control disorder and may represent a good animal model for trichotillomania in humans. Stress seems to play a complex role in the development and maintenance of some behavioral dermatopathies, but genetics and experiences, especially during development, also likely play a role. Pain or discomfort may underlie the development of many of these problems.
