When I looked at that first picture I thought of my Taggart. The brown markings on the right side of his face (looking at the pic) look just like Taggarts brown markings. And Taggarts markings are only on his face, ears and one on his back and one big one by the base of his tail.
But the ears are not perky enough for an Aussie, IMO. I can safely say I do NOT see any Cattle Dog, and definitely not a purebred one.
He is a cutie though.
