Conditioned dogs.

dodgegirl, when you go on your walks with your dog don't just walk him on a short lead rope . If you are walking out in the wide open like fields and such were there is plenty of room put your dog on a about a 25' 30' foot rope are even longer if the room lets you. What this does is if you start out walking a mile on a short lead rope the dog has no room to move but if you use the 25'30' foot rope this dog can get out and run round and round you and by the time you get to your mile your dog has done really walked are ran twice that much so a mile equals two miles if you think that is what he has done. Twice as much walking in one walk !

I would not try and pull to much weight with him he is still young . Walk him out rub him down let him have alittle break and then put him on the spring pole for a few mins are so then walk him out again half the distance you started out with . But you know you have to watch your dog and don't let him get over heated any signs of that quit and come back the next day. Its not like you are working him out for a competition just trying to put some shape on him.

LOL you do all this and you yourself will be hard as nails LOL. I bet we were walking dogs five six seven miles a nite at one time have some one watching the jenny with a dog while we were walking one out then we get back with that one and he would go on the jenny and the other one would come off and we would walk him out then rub him down then all the other stuff and put him up for the nite .
