Congenital Hypothyroidism (Tenterfield Terriers)
Congenital hypothyroidism is a hereditary condition that affects Tenterfield Terriers, among other breeds. This condition is characterized by the inability to produce adequate levels of thyroxine (T4), a hormone critical for regulating metabolism and overall development. The genetic mutation was first identified in Tenterfield Terriers and is particularly concerning due to its impact on skeletal development along with other physiological systems.
