Isn't that a bit of a misrepresentation of the problem though? The genetic problems that bulldogs exhibit aren't results of the traits you mention, but of conformance to a breed standard and the trends of a very small minority of bulldog owners (those that show them). Unfortunately, that small minority drives the cost of bulldogs and thus drives the breeders. If the bulldog standard was revised to a healthier expecta…
I'm uncertain of that. American bulldogs, for instance, are much more demanding than English bulldogs. Part of what you're buying in a bulldog is a low-energy dog.
Granted I have no idea about dog breeding but you can see in the history of the bulldog itself that it is getting more exaggerated in the traits that make it less healthy. Do we know if they are getting more companionable?
