The optimal timing for sterilization in female German Shepherds is a complex issue with considerations extending beyond simple convenience. This decision involves balancing potential health benefits with risks associated with altering natural hormone production and skeletal development.
Early spaying can eliminate the risk of pyometra, a life-threatening uterine infection, and significantly reduce the likelihood of mammary cancer. However, delaying the procedure allows for complete skeletal maturation, potentially reducing the risk of certain orthopedic conditions common in the breed, such as hip and elbow dysplasia, as well as cranial cruciate ligament rupture. Historical practice often involved performing the procedure before the first heat cycle, but more recent research suggests this timing may not be universally beneficial.
