The benefits of neutering a Sheltie reduce aggression. A neutered dog has a milder temperament and will not only have a calmer personality and improved concentration, but also reduce the frequency of howling. Reduces the chance of prostate disease, testicular cancer, hernias, and perianal adenomas. Not being attracted to dogs in heat, spaying and neutering also prevents dogs from running loose and wandering off because of heat. Parents who are interested in having a puppy should at least have their dog examined and have the risk assessed by a physician before deciding.
