Jack looks like a dog I used to have named Bocephus (Bo). He was a BLUE german shepard mix... Where most german sheps have black and then the tan and white markings, he was blue with tan and white markings. He was german shep/blck mouth curr/austr. shepard mix. I'll dig up some pics to post. He was one of my all time favorite dogs and a great fishing buddy...He also loved to taste my cigar smoke in his mouth lol, go figure...
