I feel the same way. I want a genetically tested pup with a history of genetically tested lineage, I put a lot of money and time into my pets and I want them healthy and around as long as possible. Of course I understand even with the best tested you can run into troubles however your odds are favored. I guess years ago people didn't care as much dogs were dogs but today they are part of the family.DM in dogs is similar to Lou Gehrig's disease in humans. It is truly terrible, and one of that many reasons that it is not recommended to randomly breed boxers. I lost 2 of my beautiful boxers to this horrible disease and I will never again purchase a boxer or any dog without full health testing from experienced breeders.
