Are "low energy" dog breeds ever healthy ones? With some of the ones I know there seems to be this correlation with poor physical health and being low in energy with the likes of bassets, mastiffs or bulldogs for instance. There are of course plenty of energetic and unhealthy dog breeds but not all energetic dog breeds are unhealthy, but low energy breeds do seem to clump into unhealthy heavily. With that in mind if a dog is low energy is it less about temperment and more down to them physically being unable to be more active or are there examples of healthy low energy dogs?
