My male and my female. Not sure why they said don't breed brindle to white. Mine were breed that way and never had problems. I have a few more but these are the main ones.
I don't think there is any real proof to the claim that they didn't breed brindle to white. Most likely more lore instead of fact in the smoke and mirrors that is the "history" of the AB.
I've owned 2. One is now in the Happy Hunting Grounds and the other I still feed...
