Making The Dog Walk Planks For Your PVC Base
Part two of the construction of your own dog walk. She uses sand and paint to give the surface grip, you can also buy additives for your paint that will create a griping surface as well. I painted my pause table with it and it lasted years. Either way you must have something to make the surface rough to avoid your dog from slipping off.
You will also note the up and down planks bounce under her small dog. You would definitely need more support for a larger dog as it could cause your dog to misstep and fall off. Once your dog is injured on an obstacle you risk the dog having aversion to completing the obstacle in the future.
