the neighbors got a doberman pup im guessin maybe 4 months old, but this dog will not go near them at all, she stays by my fence close to my dogs, she will let me pet her only and she barks at the neighbors kids and growls, i give her a firm no everytime i see her do it, also she is very timid when u go to pet her shell run or lay down and never wags her tail, i know nothing about this breed , but i dont want the dog to get older and bite one of there kids or one of my neices, she has the potential to be a good dog, any advice on getting her to come out of her shell??, i would really appreciate it
