It is great to read that so many people these days are prepared to use food as a means of training their dogs. Thank God the days of jerk, yank and yell are coming to an end. Food, or let's say motivation, is currently the best way to teach a dog what we want from him/her. In the process of learning, the dog does not make mistakes any more than we humans do when we are learning. The process of learning is not a mistake. But when we, or our dogs, are inappropriately corrected in the learning process, it a becomes an incomprehensible punishment that creates anxiety and stress. In this state, no being can learn effectively and usually develops an aversion to the lesson. We have no right to do that to any being, including man's best friend.
The point about using food is that it addresses the dog's prey drive in a species-specific manner, giving the dog an opportunity to give expression to his prey drive in controlled circumstances. The prey drive is flowing freely, the dog is calm and in this state can think and take in what the handler wants from him. Kevin Behan's book, Natural Dog Training, explains this really well.
Gottfried Dildei's tapes on obedience training are excellent and he clearly demonstrates the reasons for food training and how to go about it. He makes a case for food as opposed to using toys as a motivator. However, we have found that some dogs work better with a toy whilst others, as Dildei maintains, just go over the top using a toy. As in all things, it works except when it doesn't, and then the handler needs to be flexible and aware in relation to his/her dog's temperament, personality and characteristics and adjust accordingly.
Dildei uses food right throughout the dog's training and trialling career and his teams usually come out with top scores. There is an ongoing debate as to whether using food is bribery and not really training and that really, the dog should work to please its owner. Of course it is bribery, albeit very cleverly used to gain the dog's WILLING cooperation whilst at the same time working through the dog's drives. It is an excellent means of gaining the cooperation of another species that does not understand our human language.
It should be every dog handler's aim to teach his/her dog in the most humane way possible to become a cooperative member of a well functioning team consisting of two different species. As the dog has no choice in what his/her task will be i.e. obedienc, fly-ball etc. and has no choice in how this is all to happen, it is the handler's duty to ensure that the training is done from a position of knowledge (who and what the dog is and what makes it a dog), awareness, sensitivity, consistency and fairness, but NO sentimentality. Food training is currently one of the best ways of achieving this. Of course the food has to be phased out so that the dog will also work when there is no food, but this needs to be properly done under the guidance of an experienced instructor. And when properly done, the heeling itself becomes a motivator, as I so well demonstrated with my last dog and is becoming the case with my current one. Although I believe that this happens because through the correct use of food training, my dogs have learnt to trust me and to so thoroughly enjoy our work together, that simply doing an obedience routine is a motivator.
So, for your dogs' sake, keep using food, but use it correctly. :D
