I'm glad others have posted the exact same thoughts I had on viewing this. I always seem to be the one who has a 'downer' on the cute animal videos or photos!

Not because I don't love animals or find them cute and funny, but because I do and it really frustrates me to see ignorant cruelty (as opposed to the willful kind which just makes me want to smack people!)

Both animals were confused, and neither were being aggressive. But the poor old doggy got proper whapped by that young deer. And it wouldn't have taken much for it to all have gone very nasty.
