I'm trying to track down an old cartoon, maybe a Hannah-Barbera but I couldn't say for sure. I think the character in question is a dog, and he's trying to do some kind of task and keeps failing. Every time he does, he looks at the camera and drawls "It di'n't work." That's all I remember about it, but if anybody has an idea what the name is, I would sure be grateful. Thanks!

I remember it but all I can think is Deputy Dog.
