Ditto EWO. When Andy Howle worked the V. Jackson's Hank dog for the first dog show against R. Byrd's pride and joy Arizona Red. I loaned him my original made Colby carpet mill. This thing was not easy for a dog to work. I quit using it over time.

I went over a few weeks later to see Andy and how things were progressing. Andy told me, I had to start hand walking that Hank dog and let him pull a car alternator across the farm fields.

I asked was their any problems. He said no matter how hard I work this dog on that Colby mill,he never gets really tired, tongue will not come out of his mouth most of the time. LOL That Hank dog did have a lot of natural stamina and endurance. Cheers
