You have to watch the whole cartoon. It's about this dog who uses a cat and a mouse to scam people into giving him steaks. Every time they bring him a steak, he smacks them around because "You forgot the gravy!" Then, when he finally gets the money to buy a butcher shop, he gets himself into a situation where the cat and mouse can get their sweet revenge. Hence the gravy.
One of my favorite moments from ANY cartoon, ever:

Yup, saw that cartoon as a kid. And that was my conclusion: ending was creepy.
