This is a question that came up and I thought it would be useful for everyone. If you are breeding a bitch/dog that came from a litter where other puppies were affected with megaesophagus, this is the best recommendation I can give. The best advice a geneticist will give you is to place all puppies into pet homes (ie. spay and neuter everyone) and don't repeat the breeding. I know that is difficult for many people to actually carry out-if you keep a dog to breed from an affected litter-do lots of pedigree research-try to find a pedigree with no megaesophagus in ANY of the lines, be honest with the other bitch/stud owner about the affected littermates, and test the entire litter that you rear at 7-8 weeks with xrays and barium at the vet. If anyone is positive, spay the bitch/neuter the dog that you kept and start over. And place all pups from this new mega litter into pet homes where they are spayed/neutered.
