If you hang out with sled dogs, you will discover they are the happiest dogs. They go nuts when they get to run or eat, and just chill in their dog houses otherwise.
I'm Australian and I might be missing some nuance about other dialects, but doggy-woggy is a completely different word from doggywog. The first is standard rhyming reduplication, while the second is ambiguous but can be read as relating to a couple of different slurs (in my dialect).
I have heard people use that word, although a good chunk were using it about themselves and with pride.
Edit: Wow, HN didn't like that. Nevermind, screw the dogs I guess, just toss the frozen ones over the cliff.
