The kneecap is a small bone on the front of the stifle to cover the joint that slides along a groove in the femur bone. Surgery is required if the problem is severe. This causes them to breath through their mouths, and work much harder on getting enough air. Sometimes there is a foamy nasal discharge from the nostrils. Eventually, it can lead to an enlarged heart and heart failure.
Treatment requires surgery to remove part of the nasal cartilages and open the nostrils up.
Another eye problem, this time with ingrown eyelashes on upper lid, and again irritating the eye over the life of the dog. Correctable with surgery.
