Shadow's behavior since the pups introduction has been remarkable. He's much more tolerant of the human handlers than he's ever been, he clearly spends time interacting and disciplining the pups and he takes his role of defending the enclosure more seriously than ever. Groups visiting the enclosure may see defensive barkhowling behavior first hand. He is relentless and often doesn't quit until the groups are escourted back into the building. A great educational moment for visitors.
