A pet stroller having a frame assembly and a cloth platform enclosure connected to a platform enclosure member that defines a base and a sidewall of a pet seating area. Upper and lower canopy bars are pivotably connected to the rear pivot blocks that are pivotable to extend or retract a canopy over the pet seating area. A cloth canopy assembly is connected to the handle and the upper and lower canopy bars, and has a cutout exposing a front portion of the lower canopy bar. An over-center latch assembly is connected to the platform enclosure member in a position aligned with the cutout on the canopy assembly. The over-center latch is movable to a latched position in which it clamps the lower canopy bar to the platform enclosure member to form an enclosed pet seating area.
