Watch all these dogs run on their dog treadmills in their dog gymCasey Chan5/23/14 12:04am615EditPromoteDismissUndismissHideGo to permalinkSometimes when you have a lot of dogs, they don't all get the exercise they need. Not these dogs though, they get to use these sweet dog treadmills at their outdoor dog gym. So even though there's a lot of dogs, they all get to be active. Well, most of them. The dog on the left is just out for a relaxing stroll.
