Kind of a strange question, but is the quality of resource guarding aggression different than other kinds of aggression (fear, dominance, social rank, etc)? Seems like when I see video of resource guarding the dog is very tight, very sharp about going in quickly for a bite or making a scene with out a lot of, I don't know, consideration or time to check things out. If there is a quality difference, does resource guarding lead to greater potential for significant injury? I think of the video Cesar Mellon's "worst bite" and it is a lab with severe food guarding.
Thanks for your input.
P.S. This is NOT a thread about Cesar Mellon.
