Just wondering how you keep your dog exercised while living in an apartment? I just adopted a 1 year old chiuhahua mix and he's pretty mellow. He is crated at night and when I go to work. So far he has settled in pretty great. With him being crated and not having access to a yard, what are some suggestions to help him get some energy out? He gets walks several times a day. I also ride horses, so he comes with me to the barn and is off the leash to wander around. I also take him with me for car rides and running errands when I can. Any other fun suggestions?
