Katie - Thank you for thoroughly explaining this so all would understand. I am the "lister" who has the GSD with an "innocent" heart murmur. Yes, she has an OFA Cardiac number. Yes, she had an ECHO done and was cleared by a cardiologist. And, since we own her brother, we took him to have an ECHO done, too. We decided that was the best way to be sure all of our bases were covered. He was normal. We also notified the breeder, and the other littermate owners we have contact with. BTW - this bitch had been to our vet on several different occasions, and we were never told there was a heart murmur. It was discovered, by a cardiologist, at an annual health clinic.

The ertification can be done by a general practitioner, a specialist, or by a ardiologist. If your dog is to get certified by a general practitioner like yself, the dog is auscultated and as long as no murmur or abnormal heart rate r rhythm is heard, then I can certify your dog's heart. If I auscultate a urmur or abnormal rhythm then the dog is required to see the cardiologist to et OFA certified. A dog with a heart murmur can only be certified if an chocardiogram is done on the dog and shows it has an innocent murmur. This ype of murmur is caused by an increased or decreased blood flow, but is not elated to congenital heart disease. In these cases the ultrasound of the heart erifies the dog does not have aortic stenosis, pulmonary stenosis, a valvular efect, regurgitation of blood through one of the valves, PDA, septal defects, tc. Any of these congenital abnormalities would be picked up on ultrasound by the cardiologist and the dog would fail the test. The cardiac est is taylored to the breed as well, some dogs require an EKG and exercise ests to become certified. We are lucky in German Shepherds to have heart efects that cause murmurs and can easily be screened. Hope that clears up the uestion about why a dog with a murmur could get certified.

(I just did a 10 1/2 year old, his skin was getting dry, came back fine, naturally didn't bother to send it in). The reason I was disappointed w/ the whole cardiac thing? I learned (through a lister, but it's actually true) that a dog w/ a murmur can still et (cardiac) certified. Scratching my head wondering what's the point???? I'd know at 6 weeks if a puppy had a problem. I don't know any serious breeder who would keep let alone breed a dog w/ a heart issue. The last time I had a dog at the vet I had the vet sign their cert, verify their chip # and sent it along to OFA w/ $15. I guess I'll start doing that, but again, for ME, pretty worthless.
