The dog was a Jack Russell terrier.
I have this series on videotape from long, long ago. It's a favorite in our family. We still make Jake/Jack jokes. Remember the natives worshiping Jack? How did that go...?
a) "Jack's not a god!" ~ Jake
b) "HE thinks he is!" ~ Corky
Actually, "Tales" drew from the same old sources as "Indy", including "Terry and the Pirates", Milt Caniff's comic strip that became a film and a series. Actually, now that I think about it, "Tales" IS a lot more like "T&TP". Toss in some of the old cliffhanger style, and they're all connected.
Jake flew a Grumman Goose called "Cutter's Goose". He'd use Jack's eye in card games, then Jack would have to wear an eyepatch, which he growled about. *snicker* Then, there was the debate about one bark/two barks; it always seemed to change around yes/no then no/yes.
Here's the Wikipedia page, which has lots more information for you: http://en.wikipedia.org/wiki/Tales_of_the_Gold_Mon...
