I think Yorkies invented the "Zoomies"
I've read in the past many
of them do this also. Buddy does his and it's hysterical. He goes
from the living room full speed, down the hall and under the bed,
comes out the other side and back down the hall around the coffee
table in the LR and back down the hall.
I laugh but I get nervous that one day he's going to hit the side
board on the bed and knock himself out. He knows just when to duck
and squirm his way from one side to the other and comes out
full speed. Amazing
P.S. Bud's not little either.
