Bulldogs in our park trot around quite happily with their owners and ' even run'
Sorry, but I think it's tragic that it should be notable that a dog can 'even run'.
I do pack walks with my dogs, meeting up with groups at the local racecourse. One winter's day we had someone join with a very handsome Bulldog, lithe and active looking, a very nice looking dog.
After half a circuit, he was puffing fit to bust. This was about 5 degrees above freezing, on an ambling/chatting walk rather than a route march.
I am very much a dog lover, but I think this breed has gone beyond redemption, and I wouldn't consider it. Even taking the breathing issues aside, you pay an horrific price (to allow for the fact that most are incapable of mating and whelping normally, so need c-sections), then insurance will cost a fortune because of all the inherent defects in the breed.
(Oh, but if you do buy a Bulldog, please don't consider not insuring unless you have access to bottomless pits of money!)
I'm sure there are some healthy ones, but I think they are the minority.
