I put no, though there may be things in NILIF that I use. I really don't know because I have never really persued it.
However, from what I have read, it seems like a non-confrontational type of leadership that helps dog owners build a better relationship with their dog or dogs. I haven't ever heard of any dog being screwed up because the owners used NILIF methods. And any method of training can be misinterpreted and poorly applied.
I think that most of the time dogs can thrive in any situation where there is structure, patience, consistency, training, and exercise. Some of us need some type of guide or map in one or more of those areas. And lots of dogs do fine even though we are less than perfect. For those dogs that need more structure, patience, consistency, training, and exercise, stuck with an owner who needs some type of guide or map, I think that NILIF, is probably better than many others, considering how many people seem to have very positive experiences with it.
