TLDR Sheep can lose wool quickly due to stress, but it doesn't cause itching or pain.
The chapter discussed anagen defluxion in sheep, a rare condition caused by various stressors such as infectious diseases, metabolic disorders, and certain drugs, leading to temporary hair shaft growth defects. Wool loss occurred rapidly, often within days of the stressor, and could be regional, multifocal, or generalized, typically showing bilateral symmetry. The skin in affected areas generally appeared normal unless secondary inflammation occurred. There were no specific breed, sex, or age predispositions, and the condition was characterized by the absence of pruritus and pain.
