Angel LOVES, LOVES, LOVES pig ears. Put one in front of her and she's happy for a good long time. And then stick a hoof in front of her, and she goes to town on that too. She also loves Bully Sticks and her squeaky elephant and bug.
Oh, and balls! She loves chasing after and pouncing on balls.
But for a more natural spin on things, she LOVES to play in fresh pinestraw. Our dog run is on a hilly area and covered in pinestraw, so she loves to roll down the hill like the little kid she is and then run up like a loon and then do it again! She is just a hoot to watch.
