So, I am going to start a new training regime and NILIF for Blazer. Ever since he came home from staying with my parents while we were taking care of my husband's great grandmother, he's been a different dog (and a pain to live with). So, he needs some re-training and re-direction.
How do you handle NILIF in a multi-dog household? Do I enforce it for both dogs? Or no? I want to use NILIF in conjunction with his command refresher and possibly some actual obedience classes (I need to find one that fits in my crazy schedule).

Mac is on a strict NILIF program because he NEEDS it and it helps him immensely, plus it keeps our house running smoothly.
and 2.) More manageable at home - I need him behaving like the dog I know he can be. He has some issues, which he has always had, but in general he has been a good dog.
