Hi--just wanted to say that Kahlua is surely a cute little puppy. Are you sure that he is Collie and Lab, because he sure looks like he might be Australian Shepherd and Lab. His coloring looks just like a red merle aussie. I have seen a lot of dogs in animal shelters that are called collies, but are actually Australian Shepherds. It would just help you understand your dog better if you knew for sure. Anyway, cudos to Kahlua!!!
