The skateboarding bulldogs has to be one of the cutest things I have seen in a long time. They were in the rose bowl parade on a float with a skate board run around the float. That has to be the greatest exercise for them. They could dip the board back over with no human help. They also had a cute little Bulldog pup named Rose. My dogs love to chase a tennis ball & retrieve it & I think that is fun & good exercise. I have an old skate board in the basement. I wonder if I would get them interested in it?
