A little more info on the late starters within the Tudor's Dibo strains. You can read in a interview of Pete Sparks of his statement that the straight bred Dibo dogs were hard biting 45 minute curs. But when crossed with the Colby line would stay all day.

Probably what was happening with a lot of the Dibo bred off spring was they did not have a Howard Heinzl to bring them along like he did Dibo. A Earl Tudor to know when to properly start schooling this type dog.

Sometimes with a mature cold dog. All it takes is transferring said dog to another yard of dogs. This is what really fired up the V. Jackson's Hank dog. V.J. sent him down to my yard and later to A. Howel's yard. When later rolled on that Obie dog of Woody Truetts. Ole Hank decided it was time to start kicking Arse and taking names. The rest was history. LOL Cheers
