This does sound like perfectly normal puppy behavior. Especially since their is "nap time" after the "hyper mode" all should be fine.
Schatzie (and now Ransom too) goes into this mode. It's amazing to see them run so darn fast and dodge all furniture (chair / table legs) in their path. Heck, I can't even somber across the room w/out stubbing a toe!!
Lucky for them they get rest afterwards....Id love to have it this good!
