Killian proves to be quite independent and extremely stubborn. His snide remarks are often elicited from the slightest sign of weakness or incompetence, such behavior caused by him being hot-potato passed from owner to owner until he reunited with his one of his pups and currently resides with her and her owner. Competitive, impatient and an undying desire to be the top dog in all situations be it for himself or his kin. This old man still has a spark within him, and he won't let it go out so easily.
