that's TERRIBLE and riduculous!!! I am so sorry you had to go through that. I think the lil' target man took his job a little to seriously. I was treated very bad at Sam's Club when Sebi was only a few months.
i would file a complaint that you understand if you don't want dogs in the store although the pup was well confined, but you did not appreciate being treated like a common criminal over a lil' dog.
good luck!!
