How to select a dog trainer:

Trainers should:
* Have a working knowledge of how to consistently and effectively deliver both cues and consequences.
* Clearly identify target behavior, the behavior that the trainer seeks to influence.
* Continuously assess training success, discontinuing or avoiding the use of techniques that do not work.
* Give dogs frequent feedback about appropriate behavior.
* Choose an approach that gives the dog the best chance of success, rather than set the dog up to display undesirable behavior for the primary purpose of punishing it.
* Base training programs on the principles of learning rather than on anecdotal remedies.
