How old is your dog? My dog used to do this. It is crazy how far he has come. I used to take him on 2-3 hours of constant running, playing, sniffing, etc at the park with other dogs and then he would come home and sprint around the house. Now he is almost always calm, quiet, and only does his sprints when he is playing with another dog. He is a year and a half.
I expected him to be crazy for a few more years, but I think he was crazy because his old owner never exercised him and had him on a poor diet with a crazy house of kids. It was cute, but I'm glad he outgrew that behavior.
