The decision to spay or neuter a Welsh Springer Spaniel should be discussed with your welshie’s breeder and based on individual circumstances, such as the dog’s age, health, and lifestyle. Spaying or neutering can help prevent unwanted litters and may have health and behavioral benefits, but it is not always necessary for every dog and current research suggests that not spaying and neutering may have more health benefits than not neutering.
Spayed and neutered dogs have a higher incidence of fatal cancers, such as hemangiosarcoma, while many of the cancers these surgeries prevent are not life threatening. In addition, the loss of growth hormones causes joint issues, such as hip dysplasia and CCL injuries. This is because the growth hormones are not there to send a signal to the brain to spot growing after they have finished developing.
