home built practice size agility dogwalk for sale. Approx. 30 inches high, middle plank 10 feet long, each end plank 6 feet long. Each plank is 10 inches wide by 2 inches thick and painted with non-slip paint. They attach with hinges, and two small sawhorses to hold it are included. Sorry no picture as it is not set up right now. It is very heavy and awkward to move, so would be best if you can set it up and not have to move it very often.
