If you can get your dog's attention by asking him to look at you then you will get a much better response to commands.
Now begin to teach your dog to look at you when there are distractions
The level of distraction can be gradually increased as your dog understands more of what is wanted of him.
These steps should not be rushed. Do not move to the next step if your dog is not succeeding at a lower level.
Touch is a way of getting your dog to follow an empty hand. This is particularly useful when teaching heelwork (walking beside you).
Most methods of getting your dog to walk with you has you holding a treat to the dogs nose while you walk along saying 'Heel'. Although we think this is teaching to walk beside us what the dog is learning is that 'Heel' means follow the food, when we get rid of the food the dog loses interest.
