The techniques work. I have seen noticeable improvement in my dog's behavior. Butterscotch was walking without pulling ahead by the end of the first lesson. Butterscotch is finally leaving the tissues alone. He used to eat them. He has manners now. He didn't used to. Today I let him come upstairs with me. He wasn't on a leash, but he walked behind me. He used to run past me on the stairs. I then put a piece of bread on the dining room table. He didn't touch it. He just sat near it waiting for me to give it to him. Before he stole bread and napkins from the table and ate them.
