I agree, this is good material for a family story... which I find is very unlikely here on NG :). The story is simple. I really thought the movie would end after the dog gave up, before he turned on the TV. Then I saw Beavis and Butthead and a few other nudges that will make some people smile... and I Loooove Beavis and Butthead.... and the story kept going.
And yes, the animation seemed a bit odd. The proportions are good, the dog is very well drawn and moves very well, but it looks like you rotoscoped from live footage only for a few movements. Especially when the dude puts on his coat. Cause it could look a little stiff at times... I liked the dog's behavior though, looked very natural.
Anyways, keep at it!
