Hi, they are called the weave poles, or weaving.
To train my dog I started out by getting some treats and a leash, and guiding the dog though the poles with them. Do this over and over till the dog is doing it easily, and knows whats going on. Then, TaDa, a master weaving. Allways stress for correctness though, if you dog misses a pole, MAKE him go back and do it. Then you can work on speed.
GOOD LUCK
Leah
