My dog a Border Collie, was always running away. I heard about Eric so I invited him to the house for a session. I told Eric about the issue. He went with the dog and the dog went to the only way out of the yard at the driveway. The dog stopped about 5 feet back from the entrance and showed him how painful it was for her at this point. She kept telling him it was painful right here. She told him she would see a rabbit outside the fence and run through the pain but she did not want to come back because it was painful to come into the yard. Well as it was I had put an underground invisible fence at the point the dog was telling Eric it was painful! Eric suggested a power gate to solve the problem. Thank you!
