I received this as a reply to a comment I made on a YouTube video:

neither wolf nor dog dominance is not a fact. Read dunbar, Coppinger, Mech, Semyonova, McConnell, McDevitt, Overall among others. Aggressiveness, yes, but not dominance. resource guarding yes, but the same dog (a) that guards a food resource against another dog (b), will have no problems vacating a sleeping place to dog b, if that resource is not important to him or if it is more important to dog b. So dogs themselves have no concept of dominance.

Thus really.. it is all about "drive" and finding the type of drive your dog has + using that to train?
