I love Victoria Stillwell, but yeah, that's not the first time she's harshed on doggie clothes. I do think that most dogs would prefer not to be dressed, but I don't think they care tremendously one way or the other. If I dress up Thor, I just try to keep in mind that it's for me, not him. I've realized he doesn't like wearing clothes even when he's cold. Considering all I do for him, I think I've earned the right to dress him in cute outfits occasionally.
I think most of the time, Victoria is trying to get the owner to recognize that they own a dog, not a doll, and she sees clothes as part of a larger problem. Usually the owners don't walk their dogs, and project their human interpretations onto their dogs' behavioral problems. At the same time, I didn't buy her explanation that a *sweater* interferes with pheramones. I'm sure those two could smell each other just fine.
There was another episode where she rhetorically asked if a mini-pom was "a real dog", and it drives me *nuts* when people make that joke. I do still think she's almost always on point.
