Agility trainers all say the same thing. Because the weaves are the hardest for your dog to master, it isessentialto have a set at home! And if you get a set that can be used both outside and inside, all the better! Here is a set that islightweight, portable, and also very versatile. The poles can be used fixed (straight up and down) or adjustable (slanted), similar to what is called the "weave-a-matic" method. The poles are 36" tall and evenly spaced apart at a standard distance of 24" (same distance used for all size dogs). Comes with free decorative tape for the poles, and easy assembly instructions. Each set comes with a free connector kit to connect two sets together and make a 12-pole set.
