I like this thread, this is a really good topic.
Just like yours, if I pull out a shirt, Tashi gets super excited. She puts her own head and arms through the holes. (it was so fun to read that a lot of other fur-babies do that!) Sometimes if I leave a worn shirt by the basket, she'll bring it to me so I can put it on her.
She's very proud of her clothes and she loves to show them off. When I first got her, she was shaved all over, and she seemed much more confident around people when I put a shirt/dress/sweater on her.
I used to be bothered when people would ask me about it, but now I just try to realize that it's a foreign concept to them. When I explain that she gets cold and shivers because she lacks and undercoat, people usually understand.
If it's family/friends asking, I always find it really fun to take off her sweater and ask her if she wants to put it back on. They're usually shocked to see that she loves it so much and practically puts it on herself.
If a stranger tries to talk to me about "spoiling" my dog, I'll cut the convo short and be done with it. My dog is the most well mannered and loved dog I've ever met, and I don't need any unsolicited advice from random passers-by on how to love my pet less. :P
