We can't really tell what this pooch is up to (being far removed from the situation and also not being dog whisperers), but according to the uploader, his owner recently cut all the branches away on his favourite tree, but that's not going to stop him from trying to get a hold of some branches.
Poor dog clearly has issues his depth perception. Someone needs to teach him the difference between small and far away. Or maybe he just has a dream of being the first actual superhero dog. Who knows.
