I have a dog that comes with me everywhere I go. Licenced to do so. But I don't approve of dogs in stores either. Not because they are "just dogs", but because people don't seem to care what their dogs do when in public places. I hesitate to bring my dog into our pet store because all dogs are welcomed there. And what do these dogs do? They pee on the bottom shelves of everything, even on bags of dog food. Some snarl and go for other dogs, the owners let their dogs chew and play with toys from the shelves etc., some have the runs and just let it go all over the floor. This store has clean up stations at every corner but the owners turn a blind eye when their dogs soil inside the store. I can count on one hand the responsible owners that do clean up an accident and you can tell they didn't expect their dog to do this. The others are just oblivious to anything their dogs do and the employees are stuck with cleaning up, they are not allowed to tell the owners to do it for fear of losing customers. I think this really sucks when owners take advantage of stores allowing pets to come in their store.
My vet puts her dogs in a carrier that she pushes, she doesn't let her dogs on the floor for fear of contracting a disease and she told me I should avoid taking mine inside for the same reasons. So in my opinion I vote that dogs shouldn't be allowed in any store if owners are so irresponsible.
