Houston K-911's Anna Barbosa tells The Dodo she thinks Roper was just so used to being on his own that he decided to go take himself for a walk. Then he "realized he had a good thing going," having people who care for him.
"Once we had him back, he no longer had any interest in roaming, escaping or going out for his independent walks," Barbosa says. "It's clear he was ready to be someone's baby and was through with the independent life he once knew. And now he is about the best-behaved dog you can ask for, and he's been taking the younger pups and fosters under his wing to teach them the ropes."
