Maxi pet stairs are designed for dogs 50 pounds and more. These models have a footprint similar to that of household stairs and can support even the largest dogs. These steps are available in 2 and 3 step models. They are constructed from plywood and are also covered with plush cut-pile commercial carpet. This step will easily support 250 LBS. Pet steps are ideal for helping our friends that are aging or have hip or leg problems climb to their favorite curling up spot. These steps are available in a variety of colors.
