I understand your feelings, I struggled for a long time just for knowing so many needed homes. Different reason completely, but I did go through a two year struggle myself.
My bulldogs are very healthy, rarely visit the vet, probably less than most other pet owners of different breeds do. Just because they are bulldogs does not brand them for a life of health issues. Good breeding and proper home and care is where it begins. Heck I rarely even give mine a benedryl.
But I have been victim of unhealthy bulldogs in the past so I also know how hard it is to see them so miserable. You would do anything to help them.
So I know how you feel, because no matter how good of a breeder you are there will be occasional health issues that happen and it's very sad and heartbreaking to go through that too.
