This took some work. Taken over the course of 3 days, this video shows how I was able to take Rip from an extremely defensive and possessive state of mind to a place of clarity. This is not a behavior you fix with corrections, especially with a strong confident dog like Rip. He needs rules, but those rules have to be fair and make sense to him.
This is just a foot in the door, we aren't near the finish line yet. This entire process was simply to set the stage for me to fully address his possessiveness.
