Spaying and Neutering saves lives! ! Spaying and Neutering is the most important way to reduce the number of animals in shelters and pet overpopulation. This routine procedure allows your pet to lead a longer happier life by preventing many medical and behavioral issues. Spaying and neutering increases health by reducing risk to breast cancer, infections of the uterus, testicular and prostate cancer and other medical conditions. This common medical procedure won't change your pets personality but can help reduce certain behaviors such as inappropriate urination and marking, howling, and roaming.
