this is one of my black mouth cur pups. He's normally not inside but this is at my grandmothers house and she insists that he come in with the other dog. He knows what the wood heater is and loves it !
It depends on the bloodline. For instance the "carnathan" line that I've had dealings with tend to be large dogs. Also a darker color. More of a red. I deal with the "Weathorford ben" line of dogs and like for them to be yellow like that pup,leggy and around 50 to 60 pounds.
