I may take you up on that, lol!
Sis, Kharma's mother is a brindle, several of her littermates were brindles, and her brother, Oliver, is a reverse, so no mutations necessary
Judy liked to breed Gamble, Kharma's sire, to a brindle bitch because it always got her at least one red fawn like Kharma. The Gamble gene ROCKS.
I would love to come out of it with some reverse brindles.
The main difference between Kharma and Shiva is that Shiva is from show lines . . . you'd almost think they were different breeds. Needless to say, I have no desire nor intention to breed to a show line dog. I love Shiva, but, to me, she's not really a Fila.
