To use, simply unfold the ramp and prop one end against a truck bed, vet table, or top step. Animals can walk up or down at a gentle incline, instead of struggling, jumping, or being lifted. With its sturdy structure and rubberized surface, this dog;ramp helps reduce arthritis and dysplasia pain, lowers the chances of injury, and cuts down on back strain. The nonslip grip is compatible with virtually all edges. In addition to its primary function, the PetSTEP Dog Ramp has any number of secondary uses.
