I have only seen this once, and it looked like it was made in the 50's or 60's. I don't know the exact name, but the program featured a dog named "Candy the Corgi". The dog accidently gets lost and then of course gets found for the happy ending. It was all live action.
It might have been called something like "Candy the Incorrigible Corgi", or something like that.
I would really be interested if any of you have seen this, and know if it is available on a DVD collection or VHS.
