LOL They all seem to have their very own reason for the "crazy burst
of energy run".
Yep, Buddy does it also.
He'll just take off and run through the condo heading for the bedrooom
and right under the bed he goes coming out the other end and down
the hall under his blue chair and around the coffee table, running 100mi
an hour while I stand there hysterical laughing and continue down the
hall again under the bed etc.
After 2 or 3 times he will finally drop in the LR and collapse exhusted
I feel bad sometimes that he does not have a yard to do this in even
though he gets walked 4x daily.

It must be nice to be free and run,
run, run.
