I've had dogs my whole life small dogs and big dogs as well, my first dog was a pitbull 2 months old,pretty much it's like having a baby, until they grow and they more active dogs,husk as well, I'm a active person as well, I love taking long walks and run and that doesnt only help me but the dog making your dog heathy and strong as well, and is important to know what kind of food you giving to your dog, meal is very import to them, special if they few months old, or even couple years more!! I do alot of activities with dogs as a running swimming teach them new things and show how much you spend time and love them :)
