LOL...yeah, this is similar to the one I'm thinking about. I distinctly remember a character (Droopy's nemesis?) holding a hand over their mouth and getting to the top of the hill and screaming "YEEEEEEE-AOOOOOOWW!". I want to say that Droopy was dressed up as a sheep and was putting nipples on bottles to feed the babies. The wolf, I guess, may have been the one getting hurt and running. The video you shared is much like the scenario I'm remembering. After seeing video in full I can say that, although not the one I'm thinking of, it is one I remember watching as a kid.
