Specific object search is among the best and most up-to-date concepts for positively influencing dog behaviour.

Searching for ZOS objects encourages concentration, search intensity, fitness and motivation of the four-legged friend. It strengthens the bond in the human-dog team and is very well suited even for older or assistance dogs.
