So before I go to fair they are pups but there drive is a good hyperness but unless I have a treat they will come u think shocking them will help our scare them not to come?
I would have the dog in a controlled environment...then I would call him to me and light him up a time or 2 and when he came up I would praise him for coming...once he comes when called I would take him out and let him range...make sure he is in range and call him in...never give the command if you think you can't back it up...don't let your emotions get the best of you...just be calm and cool when training...the dog will trust you and will learn quite a bit faster...
I need to explain controlled environment...for me it is in a place where I know I have control over the dog...if you shock the dog where he can run out of range then you just trained the dog to run out of range and he can hunt to his hearts content...once the dog has it down in a controlled setting then move the training elsewhere.
keeping calm and cool when training will teach the dog that you are trustworthy and reliable and nothing bad will happen to him when he is around you...so when unpleasant things happen to him coming to you will make it better...
