Positive and Negative Reinforcement

Note: The information in the following article came from an interview with Dr. Ian Dunbar, who spent nine years studying the social behavior of dogs during the study mentioned below. In an earlier version of this article, Dr. L. David Mech was credited with the 30-year study. This was a mistake. The researcher who conducted the study was Dr. Frank Beach. An effort has been made to correct this error. However, if you know of a place where the original article was published, please notify the editor and request a correction.

The original alpha/dominance model was born out of short-term studies of wolf packs done in the 1940s. These were the first studies of their kind. These studies were a good start, but later research has essentially disproved most of the findings. There were three major flaws in these studies:

These were short-term studies, so the researchers concentrated on the most obvious, overt parts of wolf life, such as hunting. The studies are therefore unrepresentative -- drawing conclusions about "wolf behavior" based on about 1% of wolf life.

The studies observed what are now known to be ritualistic displays and misinterpreted them. Unfortunately, this is where the bulk of the "dominance model" comes from, and though the information has been soundly disproved, it still thrives in the dog training myths.

For example, alpha rolls. The early researchers saw this behavior and concluded that the higher-ranking wolf was forcibly rolling the subordinate to exert his dominance. Well, not exactly. This is actually an "appeasement ritual" instigated by the SUBORDINATE wolf. The subordinate offers his muzzle, and when the higher-ranking wolf "pins" it, the lower-ranking wolf voluntarily rolls and presents his belly. There is NO force. It is all entirely voluntary.

A wolf would flip another wolf against his will ONLY if he were planning to kill it. Can you imagine what a forced alpha roll does to the psyche of our dogs?
