I suspect that Sam, now 15 months old, is going through his teenage years. No he has not started wearing a "hoody" and he doesn't have a mobile phone however his recent behaviour leaves a lot to be desired…When playing with other dogs in the park he has started to give them a friendly nip…as you will appreciate whilst some dogs and more particularly their owners don’t find this recent trait too endearing and who can blame them! The question is what can we do to stop him or is this something he will grow out of? Any ideas appreciated thanks.
