Hi, First I would barium x-ray your female to make sure she is not affected. Yes I would breed her again provided she is clear but I would use another male ....... though sadly finding one that hasn't produced it might be very difficult as most breeders do not want to admit having problems. I know many years ago I was slammed when I spoke out about my mega problems including naming the sire and dam (the dam was several generations of my breeding) the sire a well known US stud dog .......... no I will not name him again but I must say his owner and breeder had no problem with me naming him and as a breeder she is someone I really admire. It is hard as if we as breeders were more honest we could solve a lot more of the issues in our wonderful breed but seeing how some breeders have been torn apart by others for admitting to issues in their bloodlines I also understand why breeders are not in any hurry to share information. The only thing I can tell you 100 % is mega does NOT always have symptoms, so if you want to be sure you must barium x-ray, having said that I don't think any breeder can afford to test for every thing that can affect their breed, we must all pick our battles. For me I barium x-ray, x-ray hips and elbows and occ have tested eyes but unless I notice a problem I do not run any other screening tests on my breeding stock except the normal vet checks. I hope your next litter is clear of mega.
