Dog Intelligence Test

We enjoy doing this recreational activity with our dogs. We give them the pistachio nuts that are really difficult to open, just a bit too tight to risk losing a fingernail over. Cee-cee, the WOW (wheaten terrier/chow mix) immediately figured out how to open it, spit out the shell, and enjoy the fruits of her labor. Gidget, the schnottie (scottie/schnauzer mix) still can't figure it out. Who has to open pistachio nuts for their mutt? I rest my case.
