Bouncer creates ruckus at PETCO

While Mom was shopping next door, I took B into a PETCO, for his second visit.  We went to the vitamins and checked-out brewers yeast, too expensive, then headed to the wildbird section for suet. On the way to that part of the store he did his customary pee against a rack. .  Passing by a large glass floor standing cage of parakeets he noticed them and began running around it and jumping against it.  Then he began to bounce and bark/growl as a sales person came to investigate.  She said, that's a terrier all right, and I replied, yes he's a terror.  I had to pick him up and carry him out of the store.
