Hello,
we start with the puppies and inexpert dogs in a field or in the wood, not in the streets ( city). We lay a t-shirt or other big clothes on the way and the victim provoke the dog with speciallyy food and nice voice. He runs 10-15 meters behind a bush or tree. The Mantrailer goes to the sniffarticel and says in the time where the dog smells on it the commando and GO!! Don´t say now everything, don´t run when the dog have much speed. Take the position for drive ski at big dogs, than you can not fall on the earth.
