that's weird about your dog this morning. it's really cool though that you can go running with your dog. one time i tried taking my dog for a run, and after about 3/4 of a mile, i turned around because my dog was all out of energy. she started out running really fast (as always), but soon she was just walking/loping along really slowly. then she got home and alternated between drinking water and flopping down on the floor. i haven't taken her for a run since then.
