We are having a spell of rainy weather here in South Dakota and my puppy is driving us crazy because he's not getting his normal exercise. I've started taking him for walks every morning, which he loves, but we live in a new construction development so when it rains he gets really muddy and I just don't have the energy to clean him up today. I tried playing fetch with him in the backyard but after about 2 throws he decides it is more fun to growl and try to keep me from getting the ball. He is not interested in any of the toys he has in the house, he just keeps chewing on me and pulling things off the table and counters in the kitchen. Anyone have any ideas for how to keep my puppy occupied?
