A few people have wondered why Air Zoey did not just jump over the gate and get her ball -- excellent question because she is fully capable of doing that.
The thing is that -- like her aunt Maize -- Zoey is a very, very good dog and she knows that jumping over the gate is not viewed with approval. Therefore, she won't do it. In addition, with Carlos/Ute sitting right there -- well, it would have been rude for her to land on him!
And so Zoey restrained herself -- because somehow Halo deVil produced a dog almost as perfect as Mrs. Maize -- remarkable as that seems!
