Update: Cain is a great dog to chill with-especially in the shade on such a hot day. I know he likes being in a kiddie pool, so I filled the pool in case he decided to take a dip, but instead, he just wanted to hang out with me. He stretched out next to where I was sitting and enjoyed watching all that was going on. He gave me good sits for treats and lit up when I praised him. He's an easy dog-easy to walk on a leash, easy to be with, and easy to love. He's a sweet, calm buddy ready to find a forever best friend.

Cain (aka Luther) is a handsome, happy-go-lucky fellow who enjoyed entertaining himself in the interaction pen. He came to me for a few treats and was friendly and polite. When I told him it was time to go, he met me at the gate and waited to be leashed. Other dogs barked at him as we passed their kennel gates, but Cain just brushed it off. Later, whenever I passed his kennel, he'd wag his tail and smile. He seems to be a friendly, easy-going boy.
