We have a 6 month old male GSD named Link. Right now he is sleeping in a 36"x22"x25" (lxwxh) wire crate. We are debating if he is going to need the next size up or not and when. Right now he is 61.5 lbs and 24 inches at the shoulder. Just wondering what size of crate everyone uses for what size of dog they have. Thanks.
