Say Good-Bye

It's been 3 months since Zoe arrived on her grandmother's doorstep. She's weathered battles with Maggie and even grown to like the animals who visit the clinic -- especially Yum-Yum, a therapy dog. Yum-Yum visits cancer patients at the children's hospital to cheer them up with his tricks. When Dr.Mac discovers Yum-Yum has cancer, Zoe sets out to train her puppy Sneakers to take Yum-Yum's place at the hospital -- but only after having to say goodbye to Yum-Yum.
