I selected that I used parts of NILIF as well.
I may not use it 100% , but I use it as a tool. When there are changes in the home, or something that has caused stress through out dogdom, I'll bring it in 100% for a little while. I think it helps bring back something that is normal to them, something they understand. Something they can count on. It helps stablize dogdom.
When I have company, and I can tell that Hondo makes them nervous, I'll give them treats to provide to Hondo. In my mind, just feeding the dog doesn't help take the edge of for the human. It might for the dog, but to the human having a large dog stare them in the eye while they hand feed them a treat might be a little intimidating. But, having the human tell the dog to sit, and receive a response from the dog gives the human a feeling of control. It helps bridge that gap.
I don't make any of my dogs work for their meals. However, if I am preparing their meals, and they have the zoomies, they will sit and wait. If they are jumping on the door to be let in, they have to sit and wait. And nobody begs at my house. That is a no-no.
Everymorning before I go to work, everyone gets a treat. They are being treated because I'm leaving. They don't work for it. Every night before I get into bed, everyone gets a treat. They don't work for it. They are being treated because it's the end of the day, quiet time. So in fact, the treats aren't exactly free - but they don't have to do anything physical to get them.
I don't think NILIF has to be black and white.
