After the holidays i realized that Sammy has gained quite a few pounds and am pretty worried about him becoming obese. So just wanted to ask how much is too much exercise for a Labrador? He's pretty active has gone traveling and hiking with us sometimes. Was wondering whether it would be nice to get him swimming sometimes and whether this really could help with the weight. He doesn't like water much so it'll be a trial and error kind of thing. Do your labrados swim or what other exercise would you recommend? It's still new year, a bit lazy getting out but i know with time will also be more active.
