Nothing puts a smile on Bella's face like when I pick up a ball, any ball!! We have been through countless balls too! Right now we have a squeeky ball that still squeeks! Amazing, since Bella quickly destroys anything with a squeeker. This has little prickly spikes all over (I guess it's made of rubber or plastic) and so she can't get to the actual ball to bite through it! If only I remembered where I bought it I would get a dozen! Catch and fetch is a BIG FAVORITE here too, followed closely by tug-o-war. As I watch her happily running after the ball I wish I had 1/2 of her energy! It doesn't take much to make them happy, does it?
