I just saw this, it feels like I just read your post about Jack not that long ago. I am so sorry for your loss. Hugs!
DM is a terrible, ugly problem. I recently read that there is now a DNA test that can be done for breeding boxers to make sure they don't have the markers for the disease. Hopefully that test will help with DM in the breed. The only problem will be the unscrupulous breeds who don't test :(
Yes, there is now a test for DM in boxers, which is great, great news! It does feel like only yesterday we lost Jack, it was a year on April 20th, but still seems like yesterday. Thank you everyone for your kind words.
