I know this is probably old, but I only just saw it a few days ago. One of the things in this program I didn't know is that Greyhounds can see 270 degrees. That totally explains how Barbie manages to avoid all the ruffians at the park who try to cut corners in order to catch her. She can see them coming and deftly accelerate to get away from him.
It also made me think that perhaps I have been trying kayaking with the wrong dog?
Barbie is such a special girl. I don't know why anyone would pass up the opportunity to have a dog just like her.
