Next you should teach him to carry his leash in his mouth and walk next to you. That cracks me up when I see a well trained dog walking themselves next to their owner.
Honestly, I would. But he's got too high of a prey drive. What I would normally do. Is just leave him drag the leash behind himself. But only on a E collar.
I will never go naked with him. Because of how high his pray drive is. And I think with his own leash in his mouth, he would know he was free.
Just thought of it, I would have to do it with his E collar...
I'll give it a shot soon.
