Walk & Talk
So often in my classes I emphasis the importance of walking and talking to a dog.
Dogs love it when you speak to them,you will find if you continually talk softly to your pet this will make your pet pay more attention to you and not stray far from you off the leash.
You will also be surprised that if you talk just above a whisper how much your dog can hear. You can experiment by softly calling the dog back, you will find that you will get an immediate response. Of course do not forget to tell your pet how pleased you are that he came back.
Dog love reward and we have many ways of rewarding a dog, but in my opinion the best way is with the voice and of course a few strokes.
