I'm not a dog person, but I would rather see a dog in a store than locked in a hot car. I saw a dog locked in a car in 80 degree weather with the window only open a crack. If people MUST take a dog to a store (which I don't see a purpose for, if someone needs that much emotional support from a pet, then they have problems)then they shouldn't get mad when they are asked to leave. It irks me too, but I just let it go. The dogs I have seen in stores are usually well behaved.
