Always make sure that you are the dominant dog! Your dog will respect you if you show your athority. You eat first. You make the rules. You are in charge of the house. when your dog realizes that then you will be able to train it easily. My dog is 4 months old and can already sit, lie down, roll over, shake, and stay. he also can use his leash. another way you should show your dominance is by NOT letting your dog pull the leash. he is not taking YOU for the walk you are taking THEM for the walk.
