Love those pics! Barney doing any 'guarding' seems laughable though! And if you think he's got the Boss wrapped around his paw....I think it's only the half of wired that Barney has the First Boss Lady!
Of course it seems laughable that Barney might do any "guarding" unless you know the Scottie temperament. Like most terriers, they are tough little dogs. I rescued one off a busy street once. A male who growled at me when I picked him up. Fortunately, he had a collar and tag, and I was able to return him to his home.
Anyway, Barney did insert himself between the media and the two leaders, and you gotta admit the image is funny. LOL!
