I agree Being the owner of two male dogs who are un-neutered, they become sexually mature around six months. My Prince started humping everything! When Paris or Gypsy was in heat we'd separate them,meaning locking him in the dining room when we couldn't watch him constantly. If you don't wish to breed, get him neutered. If you do wish to breed, find an acceptable female dog. That means that both dogs have a clean bill of health. You dog should weigh less then the female. |
