I call this the corgi "psycho run." Every corgi I have ever know goes on a crazy run throughout the house until they are exhausted. Do any of your corgis do this? It's sooo funny!
Kyoshi does that all the time. I guess they have their bursts of hyperness they need to release every once in awhile. It cracks us up though. He'll be chillin, chewing on his rawhide, then all of a sudden he'll jump up do 5-10 laps around the living room, then keel over on his side with his tongue wagging, breathing hard. Pure comedy.
