Oh, neat! I've never met a Coolie. I did have a pup come in for a nail trim today that looks highly similar to that pup, and the woman was calling it a shep/heeler. I was telling her that the merle coloring -- it definitely wasn't ticking -- wouldn't have come from a shepherd or a heeler, and my first thought was the pup was a Catahoula. I didn't know for sure. I can't imagine her pup is a Coolie, but still, the resemblance is uncanny.
