Agility trainers all say the same thing.  Because the weaves are the hardest for your dog to master, it is essential to 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 is lightweight, 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 20" (same distance used for all size dogs).  Comes with free decorative tape for the poles, and easy assembly instructions. Order two sets and get a free connector kit to connect them together to make a 12-pole set.  

Shipping to the 48 continental US is included in the price.
