Lol, Al. Oh they are pretty bad, cancer, epilepsy, congenital heart issues like DCM and others, allergies and other skin issues... but for a short faced dog, breathing is not a common of one. Some collapse after exercise, but this is usually doe to a heart condition, not lung as most people think. If you can find a working, health tested one, its a hell of a dog, but that goes for any breed/breeding. There is no such thing as a perfectly healthy breed, just examples of the breed. :)
