Abstract: An apparatus for a foldable treadmill for pets includes a front frame, a rear frame, at least two hinges, at least two stabilizing mechanisms, a belt, an overhead bar, and a pair of side panels. The front frame and the rear frame pivotally connected to each other by the at least two hinges, which allows the front frame and the rear frame to move in between a folded position and an unfolded position. The at least two stabilizing mechanisms linearly secures the front frame and the rear frame at the unfolded position. The belt is linearly positioned around the front frame and the rear frame where a motorized front roller and a back roller rotate the belt. The overhead bar and the pair of side panels create a restricted area so that pets can exercise on the rotating belt.
