I've had dogs and cats all my life. God gave us a great gift giving us dogs. I've had dogs of all sizes, small and big, and have always loved spending time with them. I'm not quite able to have a dog right now so figured this would be perfect for getting my dog fix. All my dogs I've had, I've trained myself. Sit, stay, roll over, open doors, etc are just some of what my dogs knew how to do.
