It'd probably be a good idea to find out if the problem is purly behavioural (due to some bad experience in the pup's past which you weren't even aware of, e.g. somebody teasing the dog from beyond the fence or something similar), developmental (as other have suggested) or genetic (arrives in a line - some features crop out even though the parents never displayed them).
Maybe contacting the owners of Genzo's sibilings would help? I suppose the breeder might also provide you with information, suggestions and advice.
Good luck, Stephanie
