This is a preventable problem,says George Simmons, veterinarian at North Florida Animal Hospital and chairman of the Animal Service Center Advisory Board. Everyone needs to be of the zero population mindset. Simmons quickly dispels the popular arguments against spaying and neutering. It's not natural. By the time he's 5 or 6 years old, an unneutered dog is a prime candidate for prostate problems and testicular cancer.
Females are susceptible to mammary tumors, uterine infections and ovarian tumors.
By eliminating a male dog's urge to roam and fight, neutering also reduces the risk of injury and infection. It's not necessary. They can relax and be part of the family. They become fat and lazy. Regular exercise and a healthy diet will keep them fit.
