Spaying helps prevent uterine infections and breast cancer. Spaying your pet before her first heat cycle decreases her risk of cancer by 80%. Neutering your male pets prevents testicular cancer and most prostate problems. Here at Five Valleys Vet Clinic, we spay and neuter cats and dogs as early as 8 weeks of age, or at 2 pounds. Several cats and dogs are euthanized at shelters every month due to overpopulation. Please spay and neuter your pets!
