3/4 inch plywood would easily support the weight of many pets such as dogs. If short material is available then a stair type ramp can be made. Example of a simple ramp could be 16" to 24" sheet of 3/4 plywood 6' to 8'feet long. Carpet installed to top side and 1x material for trim to sides of ramp.
