I'm generally not a dog person, and dogs in costumes make me cringe, but this was actually pretty funny.
I love dogs, but people who put them in costumes generally make me cringe. Actually I want to put the owner in an equally embarassing costume and drag them around on a leash. But that said, that one was funny. I wondered when I first saw it if perhaps the dog had sustained a back injury and had to have one of those little "carts" you see dogs with broken backs running around on. Since it wasn't mentioned, I guess not. But that would make the disabled dog a bit less of a subject of pity and one of "cute".
Well, so far I am 0 for 2; not a music lover and don't care for dogs. I can't begin to imagine what other disappointment I have in store for you.
