It seems many of the pet trainers promote pure positive training procedures. An example is this quote taken for a website… “all subscribe to positive training methods. What this means is that dogs will not be yelled at, jerked, pinched, or treated in other ways normally associated with punishment. In fact, rather than punishing for undesirable behavior, positive training methods mean rewarding a dog for the desired behaviors.”
When trainers say they are using strick positive reinfocement thy are attempting to use what is known as “Differential Reinforcement of either alternative or incompatible behaviors. (DRA or DRI) They are also attempting to use pure extinction training. This concept can be very misleading and is not always the correct approach.
DRA and DRI work well in controlled environments. Their use is essential when first training a skill. The first rule of training any animal is the trainer must be in control of the reinforcement used. If they are in an area where reinforcement cannot be controlled this concept will not work. The textbook application involves starting in a controlled environment then slowly increasing distractions. This concept works perfectly if the reinforcer used is the highest on the dog’s reinforcement hierarchy. However if not it you and the dog are being set up for failure and embarrassment.
This approach does not always work in real world conditions. For example, every time you do a certain task your boss lays out a twenty dollar bill for you. Then one time he lays out a 1,5,10, and 20. Which one will you take? The next time a 20, 50, and 100 dollar bills are placed. Which will you take? Most people given the choice will take the highest reinforcement available. Dogs are no different.
Let’s say your trainer is using a food treat but your dog’s prey instincts are easy to stimulate. It would really rather chase a cat or squirrel then take a treat. You have your dog off leash and a cat or squirrel suddenly passes your dog what is it going to do? Just like you given the choice it will do what has the highest reinforcement value. Since your voice has no negative effect on the dog, and it has never been corrected other than being ignored your dog is likely off to the races. It does not care if you ignore it while it chases something. As a owner and one paying for services you have the choice, you can have a dog that knows the skill but only performs it when it wants to. You can choose a trainer who understands the importance of positive training, but also understands the application of escape and avoidance training and how to apply each at the proper time. In the end it is your dog, and your money. Remember obedience is the dog responding because you said so not because you have a treat.
