No I wouldn't think ten minutes at 13 months would be a problem. I usually dont put to much on my dogs until 15 months but I am not one to wrap thjem in cotton wool and believe that if the hips etc are truly so bad that you cannot give at least a good amount of exercise as they grow then chances are that the hips were bad any way and you would of had problems no matter what you did.
