This was supposed to be a photo of a 13-lines Ground Squirrel but instead our dog Cooper took the center stage. We were at the observation parking lot at the airport again this evening. There is a burrow in the slope of the hill where I have photographed these little critters before. While waiting for an airplane to land one of the ground squirrels stuck its head out of the hole. The instinct of the Rat Terrier in Cooper (he is probably a mix of Rat Terrier and Blue Healer) took over and he started chasing the little squirrel immediately. The squirrel disappeared rapidly with a loud squeal. For the next forty-five minutes the dog guarded the hole with utmost attention but I guess the squirrel had better things to do than messing with Cooper… ;-)
