IPO is a three-part sport which includes Tracking, Obedience and Protection phases – the dog must pass all three phases in the trial. To succeed in the protection aspect of the sport, the successful IPO candidate must possess a basic level of instinctual drives, solid nerves, desire, and willingness to perform the work with their handler.
We train for the BH, the IPO-I and IPO-II and IPO-III level and still actively compete in this sport.
I am often asked what traits should I see in a puppy that can perform well in the sport of IPO? I feel the right training brings the correct genetics to foreground, otherwise you will simply have a nice pet. Besides high prey drive and good nerves and stable character, the most important part in choosing any breeder or any dog is good health.
