Short, sweet and sick
All at the same time, which is quite impressive. I'm not really a fan of the music, as it sounds like it goes out of tune every now and again.
I think you've put quite a bit of effort into the drawing of Jay and then slightly less into drawing things like the dog. For me, it showed, as it didn't seem so smooth, but why would it if you were just going to kill it off a few frames later.
I'd personally like to see it being a little longer, as you coudl make it up to about half a minute longer and still get away with calling it a short. Maybe Jay stops when he sees the dog, then tries to call it over. When it doesn't come, he leaps on it and makes it into dinner. Maybe a few little sound effects, to make the music a little secondary, like a slash of the knife, a thud as he lands on the floor etc.
Little touches that make all the difference, but it's worth having a think about.
