@chai2,
At the same timeframe that Jack was on TV (early 60s) ,
Sgt Preston of the Yukon had a husky named Yukon King.

@Ragman,
But I listened on the radio at a friend's house back in 1950, when I was eight, or near eight. Ann Dalton. It was magic. I wonder where King's woof came from..
I exercised with Jack LaLane after my second baby. Just good old calasthinics (however you spell that). Wow, see the size of those upper arms a few posts back? They're bigger than his butt.
Well, I think he had lots of fun in his work.
