Is there one way to train Treibball? There are as many different methods of training dogs successfully as there are dog/handler combinations. NATE supports and encourages the use of reward-based training. NATE discourages coercive, punitive, intimidating or forcible training techniques. Handlers who use abusive methods in competition will be eliminated. Reward-based, force-free training is the dog-friendly way to get fast and reliable distance behaviors to set your dog up for success.
