Guess it's time to stick some Canuck voice in here also. So far haven't seen Devil mentioned who seems to show up even more than Cotton and is a great sire of numerous great dogs.
And I have to include Sprint in there who has donated to the game also but it seems like some of the top producing females are being left out of this. Takes a good stud but with out out a great female they would never throw anything.
My hat goes off to the breeders who take a chance with there females to try the unknown studs who end up making them great. Maybe some day we will find that perfect combination in an out cross or a line breeding that will produce the next really great Goldens with no health problems to go and beat those black dogs.
