Doggy discipline

Disciplining my dog is something I do believe I’m going to start having to do more of when it comes to people coming to the door. He’s a great watchdog and will bark like crazy, but as hes getting older, he’s also getting a bit mean when it comes to people he hasn’t seen in awhile coming over. This is not cool, considering the holidays are upon us and visitors are coming and going. I worry that he is going to bite someone who is a friend or family member. So, a bit of doggy discipline in in order for him. Not too much, as I still want him to be a watch dog, but well…not for him to bite people unless they are breaking in or unless someone hurts me.
