What's REALLY going on with your dog??

And what is the real issue that you need to work on?

Growling / snapping / baring teeth / lunging are not "behaviours" that need fixing .... They are communication.

It's your dog trying to tell you that he is worried about something.

The bite comes when you ignore your dogs communications.
