All agility trainers say the same thing. Because the weaves are the hardest for your dog to master, it is essential to have your own set at home. You can't get simpler than this set - just push the spiked poles into the ground approximately 19"-21" apart in a straight line. The poles are 30" tall. Included is free colored tape for decorating the poles, and a 20" spacer stick to help you space them evenly apart (you space them the same for all size dogs).
