Kathy here: we do not put our sharp knives in the dishwasher; it dulls them. I had Yogi tethered to me in the kitchen and I was hand washing the knives. I looked down and Yogi was in the dishwasher. I told him, "Yogi, that is silly, you are a dog, not a dish".
During quiet time Yogi did a search of Doogle images and pushed his iPaw over for me to see. Apparently he is not alone.
