they should take him to training classes there is someone on here does training classes for dogs .or if he full of energy put him on a treadmill for extra exersize.I fostered a puppy who went on day and night and put him on it that way it will tire him out and loose the boredom .has he had his jabs and everything?also nuetering will calm him down.its a shame why get the poor boy and get rid of him its not his fault.
