I have no idea. I've been trying to find it... And yes that is what it is. Because I've seen dogs coming from tense, stressful homes doing something such as obsessively licking, chewing, whining, pacing, panting etc because they are trying to release the build up of tension they had lived or grown up around. I've let one dog release his tension, because I corrected him and he flipped out, I just held him calmly, letting his throw himself here and there, bite at my hands, growl, bark, snarl, and basically a full blown explosion of a tantrum! After he laid there, panting. He was pretty awesome afterwards I tell you!!
I dunno how to release this booger's tension :(
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
