Just a quick google search.
Bulldogs have a plethora of health problems including cardiac and respiratory disease, hip dysplasia, cherry eye, and other concerns. They are extremely susceptible to heat problems, can easily drown in swimming pools or other water, and require daily cleaning of their skin folds to avoid problems.
Believe this because a friend of mine had a gorgeous bulldog and it had the eye issue, hip issue and a couple others. And it farted all the fucking time, but it wasn't a slobbering dog.
