It is amazing how pups change during this time termed the Transition period, before their hearing is fully developed. Noteable behaviors and physical developments that occurred today include: Ears standing erect for short periods of time, awareness of gate noise and human voices, pups very alert to the howling of the Exhibit Pack, growling and barking in their sleep, and teething, as the upper incisor teeth emerged early this morning. Wolf Pup # 1 also had a head-shake reflex, this will later be associated with predatory behavior, when hunting, wolves will vigorously shake something to kill it. At this age, this is likely a reflex, not a true behavioral response.
