awesome pics of a great dog!!the one i have left is liver and tan, but man what a cow dog!!they are whip smart, and loyal and tough. one of the best working stock dog breeds IMO.not high strung like collies, can handle the heat, incredibly agile, not face biters like other working dogs can be- my kid would crawl all over them, never heard them growl once.and they just love to work.yours looks like a nice alert dog, does yours have one floppy ear-same as mine.
