Any of you runners want to take a dog out for a spin?

Any of you runners want to take a dog out for a spin? I've got one crated and she has some energy to burn. Unfortunately, I can't keep up and don't have too many options for letting her exercise safely.  The best I can do at the moment is put all the dogs out and give her the dog room for a while. But that's nothing like fresh air and a friend!
