I remember them well. Growing up in the early 1960's it was a great way to enjoy a Saturday morning with a big bowl of cereal and crowd around the big black and white tv. My favorite Deputy Dawg episode involved D D trying to catch a wayward steam shovel that he and the other varmits called the "Prehisterical Monster".
Oh, and my favorite cartoon that year was Beany and Cecil which was the creation of Bob Clampett after he had left the old Warner Brothers studios a few years before. Fun fact: One of the TerryToons animators of Deputy Dawg was a young man named Don Bluth that would later see his animation come out in the late 1960's was called The Mighty Heroes. I still watch it from time to time over at YouTube.
