A generally horizontal platform has connected to a first end thereof a sloping ramp that extends into the water of a swimming pool. The ramp is provided with traction enhancing ribs to enable a pet to extricate itself from a pool should it accidentally fall in or tire from swimming. In a first embodiment, adjustable legs sit on the bottom of the pool and support a first end of the ramp while the horizontal platform is secured to decking to prevent its horizontal and vertical movement relative to the upper edge of the pool. In a second embodiment, a second ramp is connected to the opposite end of the horizontal platform and legs support the second ramp on a ground portion external to the pool. In a third embodiment, the ramp is cantilevered over the pool and buoyancy within the submersed sloping ramp provides support.
