Too much of a good thing?

Ok, Priss is over the top with self esteem-so much so that she took off down the street to follow after a short coated border collie male. Yes, he was a hunk, but she refused to come back and I ended up hurting my ankle chasing her. Little snot. And this not five minutes after she won kudos for being the first and best dog nail trim of the day. Grrrr.
