Training a dog isn't something you do and are done with. Training a dog lasts for as long as you keep it up and are consistent in the results you expect. It takes constant reinforcement and repetition. You train your dog to sit and every time you give the command and he does, you are training. What is most important is that you continue to reward your dog whether you use an "atta boy", a treat, or a pat.
