Existential food is the most powerful reward you have in training your dog because he needs that food to survive. Dessert training is not as effective because the dog gets satiated. The dog also does not need desserts to survive.
... If the dog decides he won’t work for it, that is no problem: no food until tomorrow, my friend. Dogs who work on existential food are serious workers, and they learn quickly.
Wie wichtig muss man sich selbst mit seinem Hobby eigentlich nehmen, um sowas als adäquates Vorgehen zu empfinden und in dieser Argumentation nix verkehrt zu finden...
