to the people saying he should of used a working grey,nobody has one.so you can't.i'd rather take a chance on one of these then the other bull x litters on here where both parents have a face like a show peach.personally i wouldn't entertain a 1/2 x,so these will do me fine.all i want from the sire is his attitude the rest i want grey.these will be basically 3/4 grey and a 1/4 bull which are more versatile and popular than any 1/2 x's.
