Meet Hummer.  Just like his vehicular namesake, he is BIG.  Hummer is about 100 pounds of sweet black lab.  He's 3 yrs old, has a big block head and nice otter tail.  Hummer came to us from local shelter when his time was up.  
Hummer's housebroken and knows some basic commands like sit and down.  Watch for updates as we get to know him better.
