grizzer – Jul 21, 2008 12:00 AM

It is apparent that high prolactin levels are affecting Grizzer’s behavior. Since the pups were introduce last May, Grizzer’s tolerance level to Malik’s growling and lunging at him had been noticeable to wolf care staff. This weekend, while Grizzer, Maya and Shadow were interacting in a playful way, Malik took advantage of this and lunge at Grizzer’s neck. Grizzer did not respond the first two times, but at the third, he turned around and chase Malik back to the upper enclosure, followed him for a while, and then went back to his business with Maya. This is quite a different behavior from the wintertime interactions.
