He should be shown, so that he fits the standard for the Rottweiler. Is he tall enough? does he have the proper conformation? does he have the right temperament? is he smart enough? Most of us are kennel blind. We all think our dogs are the best, the smartest, the perfect dog.
That's why you get an unbiased opinion.
I don't think OFA's are all that expensive....x-rays by your own vet, and then sent to OFA. Eyes are often done at a clinic at dog shows, and hearts can be done at them too...or else done at a vet cardiologist.
What titles does your dog have? What titles does the bitch have? anything in obedience, tracking, herding,agility? The rottweiler is a working breed, you should be able to prove that the dog can learn and work.
I also have to wonder why the bitch owner that has gone to all of the trouble to get OFA certification on their bitch, would want to use your unproven 9 year old dog as a stud???
Good proven stud dogs are around, as well as semen can be shipped.
BYB's like to use the dog that is closest to them....as long as they can perform, they will do.
