Wow, sounds fantastic.
What is the name of the brother, and do you (or can Kilo) get a photo of him?
He deserves to be in the database, as well as the winner.
See if you can get the photos of those dogs, and the ped of the winner, I would appreciate that.
Good to hear that you're absorbing the info ... I am one of the few breeders, if any, who has kept an unbroken string of winners/Champions dating all the way back to the first two dogs I bred ... spanning more than 20 years, and producing Champions with 6-gen of my (or mostly my) breedings.
I don't "think" ... I know that these principles work
If you follow the patterns, advise, and standards, you can breed your own family, successfully (which is the key!), for as long as you are alive.
A lot of people breed "pure families" that can't do anything, which is not what you want. All families will produce some bad eggs, but you have to keep exact standards in mind to make your produced dogs repeatedly and consistently stand the test of time.
That said, I never liked Big Boom. From what I understand, he was not a head dog and he didn't have any ability. He also doesn't look long-winded to me with that snub-nose.
But Big Boom does have good dogs behind him, though, so he may well produce, especially when bred to a bitch the quality and breeding of Gorilla Girl ... as King Kong and his brother apparently prove
