I have a cardinal but we use 3 2x12 blocks with the grain alalternating screwed together. Then we bought a stall pad from tractor supply and cut it to the same size as the block tops. Keeps the rams from extending . seems pretty solid when the dogs are jumping around inside.
Stall pad is made from recycled tires and helps take out some of the pop and crack that happens with temperature changes.
