Hi! I'm in the process of selecting a new boxer baby to bring home. I've talked to the breeder extensively, and I feel mostly confident that I'm doing the right thing by purchasing through her, but I have a couple of questions I'm hoping y'all can help with. Heart murmur: one of the two puppies in question presented with a heart murmur a few weeks ago. At that time it was a grade 1 and the vet was unconcerned, saying that it's fairly common and should disappear by 16 weeks. Pup is now 10 weeks and was in today for eval. Vet found no murmur and considers it a resolved issue. Should *I* consider it a resolved issue, or should I be concerned that this might be a sign of things to come? Degenerative myelopathy: the dam was tested and is a carrier. The sire was not tested before his death, but lived to be something like 10 or 12 years old. He's a sperm donor sire to this litter. I understand that there are now DNA tests for DM and that 50-something percent of boxers are considered "at risk" of developing DM, though being "at risk" doesn't necessarily mean it will ever present in the dog's lifetime. I have no intentions of ever breeding, so I'm really concerned from a health standpoint. I understand this is considered to be an "old dog disease" and generally doesn't hit until age 8ish, but also can present earlier. I expect the lifespan of this dog - based upon our experiences with other boxers - to be 8-10 years, with or without the development of DM. All other recommended health testing has been done on the sire and dam with good results. I'm pleased at the otherwise proactive health testing the breeder has completed, but am reasonably concerned about the DM. Given this information, do you have any advice regarding whether I should proceed with a puppy from this litter. There are only 2 pups left, and the girl is the one that presented with a murmur. I'm not "sold" yet on either one and - at least right now - could go either way. Any advice would be greatly appreciated.
