Is My Bichon Frise Crazy?

by Martha
(West Kingston, RI)

At the end of the night, right before Sir Isaac, my bichon frise, is about to settle down to sleep, he suddenly and for no apparent reason, spaces out and starts growling and running in circles around the house at top speed. He does this for about two minutes, then he crashes.

He also does it after baths(He does not like being wet and will 'hold it' for days to avoid having to go out in the rain).

My question is: Is this normal behavior for this breed? I mean, it's hillarious but I wonder if he has a screw loose.

Sir Isaac gets plenty of exercise during the day. We run several miles a day together. I've had dogs my whole life, but not small breeds, and I've not seen this behavior before.
Thanks...
