Hello to everyone. I am new here. I found this forum while searching for dog training forums and hope this forum will be able to help me train and calm down a very aggressive black lab mix dog. I have been able to calm him down to the point he doesn't try to eat his kennel down when someone visits as long as I am outside to tell him no but he needs a lot of work yet and I am hoping the kind staff and members of this forum can lead me in the correct direction since I can't afford to hire a professional. I've never dealt with a large aggressive dog before so it's brand new to me.
