Ha, I take "small" morsels of food out of my mouth, and feed it to my guys. Most of you will think that's more gross than spitting on their food !
However, I think that scent/action is a VERY powerful Leader "tool" for me. I always feed My Male Sneakers first, then My Female Becca, then My Male Puppy Ichabod, and all three of them sit patiently (now) during that sequence. When each of them were Puppies, they "jumped the gun" trying to be first to receive the morsel, but have learned the "Pecking Order".
I operate/run/control my Pack quite differently than that which Cesar and some "Experts" suggest. I always demand to be Leader, BUT, am very supportive of My Male Sneakers being the Alpha. He's First Dog, Biggest Dog, and MY choice to "lead" his subordinates. I'm not sure if all will understand the leader/alpha difference there. I differ in handling my dogs in several other ways as well. Allowing Sneakers to take "point" ahead of me during a hunt, is another of them.
