I don't understand people who get dogs, then get upset when they bark!! They're DOGS! Dogs bark! My Gambit isn't much of a barker so I'm lucky, in fact he only barks when his toy falls off the couch and he wants me to pick it up for him (yes, he's incredibly spoiled!) but even if he was, I would never, ever, strap a collar on him that would shock him! I wish I could take all the silly dog owners who have shock collars on their dogs and zap them on the throat a few times. If you're too lazy to work with your dog on "settling", as I tell Gambit when he gets excited and close to barking, then you don't deserve to have one! If the customer thought the barking was such a big deal she should call The Dog Whisperer!
He could train her to work with her poor dog! Things like this get me so worked up I could...Well, bark.
