The only way you can build a bond of mutual trust between you and your dog is for you to praise good behavior whenever it is displayed. A dog learns to be shy or aggressive whenever his behavior is punished. Verbal praise is given with a slightly higher pitch in your voice and with lots of expression. A happy tone in your voice, a smile on your face and a kneeling body position will tell your dog that you are pleased with his progress. A pat on his chest at the time of verbal praise will reinforce your expression of happiness.
Dogs have a keen sense of hearing.
They learn best when commands are spoken softly and firmly. Consistency and simplicity in giving commands will hasten the learning process. A dog that has a tendency to jump up on you will learn that he gets lots of smiles and praise when he comes up to you and sits. A dog is easily trained by the use of food tidbits as lures and rewards. If you want your dog to pay attention to you when teaching him to walk on leash, carry a food lure in your hand.
