Here is a video by the SPCA in New Zealand. They taught 3 rescue dogs to drive a modified car using only positive reinforcement methods. Its amazing what you can do with a clicker, a handful of treats, and your imagination
The latest research on modifying dogs’ behaviors shows that consistent positive reinforcement within 3 seconds of a behavior we wish to see repeated is the quickest, kindest and most lasting way to train a dog. My lessons will show you how to use this to teach your dog everything from a basic ‘sit’ to opening and closing doors (if you want him to!). Remember, food isn’t the only reward you can offer your dog. Sometimes a ‘good boy’ and a pat on the head will do it. Other dogs will want to play with a ball. I will always recommend starting training with food treats, as it is the quickest and most primal way to reward your dog, but training will also include fading the food rewards and/or replacing with non-food rewards.
