What exactly is a Do-Over Dog? It might be a shelter dog you’re working with to help her become more adoptable. Perhaps it’s the dog you’ve adopted, rescued, or even found running stray who is now yours to live with and loveforever. Or it could be the dog you’ve lived with for years but you realize he still has issues that make him a challenging canine companion. A Do-Over Dog is any dog that you think needsmake that deservesa second chance in life.
