My dog is a DM carrier. Can he still be a sire for a breeding line?

Updated On September 23rd, 2025

Pet's info: Dog | Boston Terrier | Male | unneutered | 6 months and 18 days old

I bought a pup , and later found out he is a carrier of DM. He was to be a sire for a breed line. To me , the DM makes him Unbreedable. Is this right ? This genetic disorder is inherited.

This would have to be judged as part of the whole picture, as there may be cases in which a breeder makes an informed decision to breed a dog who is a carrier of a genetic problem if there are a number of significant good things about the dog that outweigh this issue - in some cases, the effects of the problem can be minimized by carefully selecting females to breed with who are clear for this genetic mutation. In general, though, I would tend to agree that a dog who is a known carrier for DM should not be bred. If you have an experienced Boston Terrier breeder who is mentoring you (perhaps the breeder your puppy came from?), he/she should be able to give some valuable insight on this issue to help you make a decision.
