Hell yes there should be a dog park area. My dog loves the one here in Boulder. Its really nice to have a place where you can just let them run free without worrying about them getting away. It would be even cooler if there was a doggy day camp where you could leave them during the race, so they don't have to stay tied to a car or whatever. Obviously you would have to press home that the dogs in that area have to be non agressive towards other dogs and people. There are signs all over the Boulder dog park saying that you are liable for your dogs actions, both financially and legally (i.e. if your dog starts a fight and tears another dog up, you get a ticket and have to pay for medical bills). I know my dog would have loved it, especially compared to staying with the car while I was boating. I bet a humane society or pet shop would be all over sponsoring that area. You'd also have to have it next to the water so they can swim and drink.
