I think some dogs may like the attention of being dressed up by their humans because they interpret it as affection, but unless it's something that you've made the dog used to from the time it was a puppy, it's probably going to always feel a little weird and unnatural to the dog. This doesn't mean I think people should never dress their dogs up as long as they do it for the right reasons. If you're putting booties and a coat on your dog to protect it from the weather, then that's a pretty legitimate reason.
