Treats, snacks, food or reward: which is it?
We as a culture (or maybe as a species), have a strange hangup with food. Food fills us with emotions and assumptions and strange relationships (chocolate!). There are still a lot of people who have a hard time even considering using food for training, thinking it somehow will diminish the relationship of that perceived (ugh) alpha status we so strive to hold over our dogs. Food is quite simply a tool, just as fetch, attention, affection, praise and others are (or money, play, vacation, etc. are for humans). The difference is in how the dog values these things at any given moment.
