This category includes most farm bred dogs, puppy farm bred dogs, small scale commercially bred dogs and casually bred dogs from occasional breeders who have not kept records of their bloodlines. (bordercollierescue.org)
If you are a serious breeder or a conscientious occasional breeder, have your dogs certified free of the trait by the OFA or, at the very least, have your veterinarian thoroughly examine your pet for a tendency to patellar luxation before considering breeding. (2ndchance.info)
Such occasional breeders rarely participate in online communities and they tend to come out of their foxhole only when the puppies are on their way. (breedingbusiness.com)
