I just glanced, but I saw something about fat danes...
Danes are thin and sleek by nature. It's actually not easy to make a dane fat, even when spayed or neutered. Danes are low key, but are also easily kept in shape. A good romp around a fenced yard once or twice a day plus a daily walk is all it takes, and that's in their prime. As seniors, it's less. Puppies on the other hand, will keep you on your toes.
I've had many danes, and I've yet to have a fat one. I do know a friend who had one, but she had medical issues and was always obese, from puppyhood until death....
Not saying it can't happen, it's just not the norm.
And yes, danes drool...but there is a give and take with any breed you'll choose. Some danes are less "wet mouthed" than others, but be wary of any breeder tauting "no drool" or "tight lipped" or "dry mouthed" danes because BYB's are now using this as a marketing ploy. There is no such thing as a dane who doesn't drool- the standard calls for a certain structure, and that structure will allow for loose lips and consequently, drool.
