Hi, I'm Walker.  This is my second time at the shelter.  The first time I only spent a day here because the folks that were watching me for my owners came to claim me right away.  Now I've been here for over a week and nobody has come to get me, so I guess they decided they no longer wanted me.  I'm a sweet boy with a wonderful disposition and an excellent sniffer (probably what got me into my current situation).  So, if you have an active lifestyle and want an active buddy, I'm your boy.
