Yep, they have been bred for their distorted swim bladders, just like balloon mollies, etc. Kind of like collie dogs - they were bred for longer and skinnier faces. This was considered a more pleasing appearance, nevermind that epilepsy is now a real problem in this breed... Same with german shepherds - breeders thought that their backs were too long. Now that the dogs have shorter sloping backs hip displasia is rampant in the breed...
When their is money to be made, animals can suffer.
