Oky I wanted to know how do you get blue brindles and tri colors. For the tri colors do have to breed dog of some black and tan in them or in the generation where the black and tan in. Cause I see some pretty one like like tri blues, tri fawns,tri black and tan and I seen one that a tri with moo moo pattern. I didn't believe that last one till I seen it but it exists. As for blue brindle I don't know but to everyone on gopitbull explain to me how is it made and what genetic code you must breed to get these beautiful apbts.
