My take on them is that they have a coat for a reason. I think the dog clothes look pretty gay. Buuuuuuut, one morning this week my Westie was actually shivering waiting to come in from the back yard. My routine is to wake up, come downstairs to let him out, go back up and take a shower, then let him back in. I felt pretty bad about that. So, I bought him a doggie sweater. It's the least gay-looking one I could find - beige. I've never seen him shiver before, so that was odd. He seems to like the damn thing, too. Yeah, I did it. Feels weird, too.
