I lost my hybrid dog today after being in the family for 13 years. Best dog I ever had. Great inside dog even though he weighed 100lbs. Never barked unless he needed to go out to fertilize the grass, was great with the kids and cats, chickens too. He was smart, sometimes too smart. He could open doors by turning door knobs with his mouth. We found out he could do that when one morning we got up and the front door was standing wide open and the dog was sitting on the porch looking in (we had forgotten to lock the door that night) I watched him open several doors after that. We sure will miss him.
