I am not a breeder but was in conversation on the phone recently to a breeder whose name I was given as responsible and health conscious. She told me she was rather disillusioned with scanning at the moment and the results and was unsure what to do next. One of her bitches was pts with late onset SM but when younger had been clear and produced a litter. The sire of the litter was scanned on the bitches death and seen to be one of the worst cases of SM the Neurologist had ever seen. The litter produced, now over 2.5 years, have been scanned and are all clear. This must be a terrible dilemma for breeders to face if they have clear stock ready for mating but fearful that their scanning clear may be a smoke screen. 2 bad cases producing a clear litter. To breed or not? Can I ask what should they do? Bet, Karlin, BrianM. I ask you because you are knowledgeable people with an opinion.
