[Discussion] For Great Dane owners who've had long healthy lives, what system did you live by with each one to ensure longevity?

About to get a Dane in two months (Merle) and wanted to follow a strict plan that someone who has handled many different Great Danes have done, that is proven for them to give their Dane the longest years they could ever ask for? If you could include:Type of food/How much food at different ages of lifeExercise schedule from young to oldAny other tricks or tips!P.S I plan to do the gastropexy or whatever it's called to reduce the chances of bloat being an issue! via /r/dogs http://ift.tt/2qGnwnW
