When Spayed or Neutered
Almost half of unspayed dogs develop breast tumors while almost none do if spayed before their first cycle, and chances are reduced if spayed later. Risks of uterine diseases are completely eliminated.
About 60% of older unneutered dogs suffer from enlarged prostate glands. Neutering lowers the risk of this painful condition as well as prostate cancer, perianal tumors or hernias and wipes out the risk of testicular tumors entirely. Neutering also reduces the tendency to roam. Most dogs killed on streets are unneutered dogs.
