I admit to being a bit prejudiced toward Boss Man... I bred a bitch to Gary's Ammertals Boss Ranger decades ago and had a nice litter that went on to do well in trials, hunting tests, NAVHDA, conformation shows, obedience trials, etc. - as well as in the brood box. I believe that was one of the last litters I had under my QUICKSILVER kennel prefix (of many years) - that's a whole 'nuther story in itself...
A lot of wonderful GSP have come and gone over these many years - but you can still find many of the "greats" in pedigrees of dogs today! It would be great if AKC would allow folks to have printouts of all dogs/generations resulting from a particular breeding -- one could really see the influence in modern generations of top dogs from the past.
Here are a couple of pics of the puppy I kept from my Boss Ranger litter.
The picture with the bell collar was as a little pup, and the stacked photo was as a 3-4yo
