No, not weird to me. I have no skinkids, so dog milestones are fantastic!
Speaking of jumping, though, I bought my daredevil stairs for the bed and am TRYING to get him to use them to instead our jumping back down. So far, mostly unsuccessful, so I bought insurance for those possible future orthopedic surgeries! I tried covering the floor with soft stuff like pillows and blankets, but that just made him jump even further in order to miss the obstructions in his landing zone.
