I agree with most people that the ending was really good. Of course, this was a bit too short to like that much. Seeing as how these characters are so popular, you could probably put them in any scenario and people would like it. It works because the bark and bite joke told at the beginning was really bad. Why a poodle of all dogs? He totally deserved it.
It helps that the animation is as good as ever. I seem to be saying that a lot. It gets pretty annoying with that guy's voice. I'm not sure why, but I like the one nostril design. Most cartoon characters don't even have nostrils.
