The little yappers probably have an inferiority complex. I'm not an expert but I do think animals, especially wolves, dogs, cats, etc have egos and maybe even a self-esteem. For example, my friend's golden retriever never barks and is always extremely anxious, shy, and submissive towards other dogs and not interested in dominance while my own dog Shadow had his limits even though he was usually peaceful and carefree. And then of course you have the a.hole dogs that pick fights with other dogs whitout even being provoked as if looking down on them. Overally I think the intelligence of animals is often underestimated.
Shall I give you dis pear?
