This is my dog Panda. He was found in a ditch at just 6 weeks old in Davis, California. I don't know what breed of dog he is but I'm sure he has wolf in him somewhere down the line. Those black lab females can be real promiscuous. He likes to howl when he hears a fire truck siren or an ambulance. This is a video of his first howl since his longtime best friend Friday, the black basset hound died. This howl sounded very mournful and eerie in particular on this morning.
