Step 11: Nailing The Rear, Front, and Side Panels Together
Place front and back panels together with side panels to form a rectangle. You will need to close these four pieces together with 1.5-inch nails. You want to do your best to get nails of such size as they work best with your plywood. If you have too long nails, you could easily endanger your dog and anyone else around the house because the nails will stick out.
One of the most important factors at this point is to make sure that you have oriented your nails correctly so they won't stick to your dog's living space. You should also not try to bend the tip of the nail down as this could still harm your dog, another animal, or someone else. Safety is always first!
