I stated without going into details but....I own the gyp I own her son I own her grandson and have tracked the breeding of this gyp...she has never hit the woods but is consistent in her offspring and their abilities. her son is a strikedog her grandson is a strikedog...several other dogs out of her that others own are strikedogs, she has a very low cull rate, this line is of old blood from LA. this isn't a random dog from let's say Florida I just got to breed to something in hopes of turning out dogs. homework, research, and knowing....
There is plenty of great bred gyps that have been bred that never were proven and produced great dogs for years on end never ending never showing many signs of culls and the bloodlines went on to history . But on the flip side there has been many of unproven great bred gyps that many a men bred and the bloodline fell on its face years into the breeding program. No one can say it will and no one can say it wont only time knows that.
I just dont do it myself because I know several ole bulldog men that done this and seen them go threw hell years later .
