I have an 8 year old fixed female English bulldog and never have had one problem with her health.  I think the reason is that she runs 2 miles with me EVERYday in the mountains, she gets carrots for treats and eats ProPlan 1/2 cup a day with coconut oil mixed in.  She is a muscular 46 pounds.

I think people buy EBs and think they are couch potatoes.  They need as much exercise as other dogs.
