Exercise

Labs have a ton of energy and need lots of exercise. If I were you, and I'm not, but if I were would teach it to play fetch and have a couple of sessions with it per day. A puppy that young won't need more than 15-20 minutes per session before it gets tired. By 6-8 months, you should be playing with it for an hour a day. Also, Labs get to be heavy dogs, so don't do too much too soon with it as far as long walks. If you want to protect their joints as they grow, ease them in to the longer stuff. My golden was a year old before he went on a walk longer than a mile to mitigate the future joint issues he is likely to have. Just my .02. Good luck!
