Hi
I dont have large breeds, but, at a guess (ish) id say, GENTLE exercise only, certainly no running up and down stairs, or long walks or hours galloping about. Just stick to playtimes, and very short training sessions.
Too much exercise will put unnecessary strain on muscles, joints, etc.
Food, well, i forget anything i have ever known about usual dog food, as i feed raw. Definately do not over feed, if anything , you are better off under feeding slightly, rather than over feeding! Carrying too much weight will also damage a pups growth.
Errrrrr, plenty of stuff to chew on, if you are familiar with the BARF diet, then large raw meaty bones, which, going from the experience i have had with my pup, will cut out on a lot of puppy chewing, an also use up a fair bit of energy, doing something that isnt harmful to his joints.
Oh, an it goes without saying DONT leave pup unattended with bones of any kind, and definately dont feed cooked bones!
