I've recently been promoted to a researcher, so the very first thing I'm doing is adding credits to the Deputy Dawg entries. You're probably asking yourself "Gee, Bryson, where'd you find them?" The answer is simple: I've come across a Cartoon Research article by Charles Brubaker called "A Deputy Dawg Follow-Up". This page is important because the main topic is related to some credit sheets, (credit is given to Jerry Beck for discovering them) which can be found in a reproduced form at the bottom of the article. Furthermore, a number of individual Deputy Dawg cartoons (with credits) are showcased on the page itself.

Sounds good! But, especially with credits, we're picky about our sources since there's a lot of bad information out there. So make sure you're citing your source. (Although Cartoon Research is a very reputable source.)

Don't worry; for the cartoons present on the article's main page, I've cited Cartoon Research, and for the credits present on the sheets, I'd cite those.

Those are official files from Viacom, I would believe them if Cartoon Research is citing them
