Here are some medical benefits on spaying and neutering I received from Liberty Veterinary Hospital’s staff. Your female companion will live a longer, healthier life. Spaying helps prevent uterine infections and breast tumors, which are malignant or cancerous in about 50 percent of dogs and 90 percent of cats. Spaying before the first heat cycle will lower cancerous tumors in females by almost 90%. Neutering your beloved male companion will prevent testicular cancer and some prostate problems he could experience later in life. Next week, I’ll go over behavioral benefits.
