Well I did 3 rounds yesterday, just to test myself out. A OK. Somewhat tired afterward, but no extra aches or pains. Plus I had a partner. He’s three and a half years old and weighs about 60 pounds, stands about 2 ft tall and has 4 feet. His name is Hugo and he lives across the street from us. He kinda hangs out over here cause his owners don’t pay him any attention and Patty felt sorry for him so I have to give him snacks and brush him. He seems to be at least part pit and just all around mutt. He is a friendly smart dog though and simply LOVES to be petted or brushed.
