I have had Black Labs all my life, since I was a kid. After I moved away from home, I got Molly, a Lab mix. She lived to be 17. Then I got Tarheel (yes I am a UNC fan!). He was a AKC Registered Lab. Tarheel lived to be 16. Rebel, my Pit/Lab mix is almost all black with a swirl of white on his chest. I fell in love with him on the shelter website and drove straight over after seeing him online. I was thrilled to see him there as he was me. Rebel seems to be 75% or more Pit Bull Terrier. He is solid muscle and leans more towards the Terrier side as he wants to chase any critter that moves. He is a couch potato, inside dog and lets me know what is going on inside and out. The hair bristles from his neck to the base of his tail when he thinks something is approaching the house.
