Hi everyone! I havnt been here in FOREVER! Hope everyone is good! I have a 5 year old Golden/Lab mix named Bear....I take him running with me all the time, about 5 days a week, we usually go for an hour (6miles) sometimes even longer....usually later in the day after our run I'll take him on a walk with my other two dogs, for an hour. So needless to say he is very active. I have always fed all my dogs once a day in the morning, Bear always gets 2 full cups (they all get Innova Senior Adult Food). Lately I have been feeling like he should get more food, considering how much running he does with me and other activities, like the walks, and the hiking too. (my other dogs are older and can only go on walks) Any idea on how much food he should be getting? Should I give him more??? He had been maintaing a weight of about 68-70lbs, lately when we go out I feel like he looks a little thinner, but when I feel his body, he does not seem thin....he has long black fur so its hard to tell by judging from the look of him. I have friends who have similar sized dogs who get a lot less exercise who feed their dogs more then him.....I guess I feel bad that I might be not giving him enough food....any suggestions? Thanks!
