Myths About Positive Reinforcement Dog Training
If I use food to train my dog he'll never work for me when I don't have food in my hand.
When training with food is done right, the dog does not become reliant on it to perform a behavior. Food is simply used initially because dogs don't have to be taught to enjoy it and work for it. Dogs also learn better when rewards are dispensed more like a slot machine and less like a vending machine. Sometimes they'll get a food reward, sometimes petting, other times a game of ball or even nothing. It becomes a game of slots to them and they "gamble" on getting a prize. Go to APDT for some guidelines to selecting a good dog trainer. You may want to look for a trainer with the CPDT certification, an indication that the trainer has a certain level of experience and knowledge about learning theory, behavior, and ethology.
Positive trainers let a dog get away with anything.
That's simply not true. Most positive dog trainers do use some form of "punishment" such as removing something a dog wants. Other trainers will teach a dog a word like "oops" or "too bad" as a way of marking "wrong answers" for the dog. You'll need to find a trainer that uses consequences for your dog that you are comfortable with, that meet your training goals, and that work for your dog.
