Q. If a F1b golden doodle's grandparent's were x-rayed and cleared of hip dysplasia, what are the chances the pup will have hip dysplasia?
A. It is possible for two OFA excellent parents to produce a dysplastic puppy, because the genetic component is so complex (environment also plays a role in the development of CHD). That said, every stud dog and brood bitch should be x-rayed before being bred to diminish the chances of having dysplastic puppies. The fact that the grandparents were cleared (by either OFA or PennHip and not simply by a veterinarian) is of some assurance, but not significant enough to rely on.
