I agree with the above. If ya can't trust them alone, don't leave them alone. LOL
My pit/boxer Smiley is a fence climber now. After 3 yrs he started his skills again. He used to climb the 20 ft chainlink at the shelter. Once in the yard with my other dogs, he showed no interest. Then he figured it out one day and the moment I go inside, up over the fence he goes. If I'm out there he stays clear.
