Tracheal collapse is a debilitating disease of the trachea and bronchi observed most commonly in small dogs. The Pomeranian is one of the more commonly affected breeds of dogs. Although some dogs can be managed with medical therapy, severely affected patients develop respiratory distress and some dogs do not survive. The frequency of tracheal collapse in small dogs, including the Pomeranian, suggests a genetic component to the disease. Investigation of the genetic basis of tracheal collapse could lead to development of improved diagnostic testing and alteration of breeding practices to reduce disease prevalence. Additionally, an improved understanding of the underlying cause of tracheal collapse could lead to improved development of medical management plans for affected dogs.

Funding for the research is provided through the collaborative efforts and generosity of the American Pomeranian Club, Inc. The AKC Canine Health Foundation supports the funding of this effort and will oversee grant administration and scientific progress.
