Hey! You can help further the research into finding the genetic marker for megaesophagus. If your dog was diagnosed with megaesopgagus before 1 year of age, you can help by sending in a sample of his DNA. You’ll need to request a kit busing the contact information in the link. You don’t need to be in the US to participate. The study is headed up by Leigh Anne Clark Ph.D out of Clemson University.
