Do you think the yellow dog on the Waltons named Reckless was a purebred Lab?
Don't remember him being a Labrador. Here is what I found on google: The original Reckless (owned by Hal Driscoll and Bill Koehler/trained by Genny Kerns) was a redbone hound named Prince. http://www.tvacres.com/dogs_hounds_reckless.htm
And here thy claim he's a Bloodhound. http://www.channelguidemag.com/articles/dogs.lasso I remember him having really big ears :)
