@Benkura:
Why are some brindles darker than others? If you use a darker brindle with a R/W what would the pups be like? (I realise there could be R/W pups too) Likewise, if you use a lighter brindle? I like the darker brindles and just wondered if there was a sure way of breeding them.
Honestly, I don't think there is a sure way. My pup Liyah's mother is dark brindle and she was bred with a black & white male. Liyah was the only brindle pup (that looks brindle - her brothers and sisters are b&w, but brindle that can't be seen) in the litter and she is chestnut red with black striping - but not heavily brindle. She is my favourite brindle colouring (because her red is so deep) as I'm not a big fan of the dark brindles.
BTW, as a back story…I wrote in my original thread that her registered name is "The Chosen One". One of the reasons we named her that was because her breeder was going to keep her, but because her red was the chestnut red of her grandmother (my girl Ruby), I begged the breeder for her. So to me she was the perfect colour combo - Ruby red with just enough brindle striping.
The photos I've posted of her don't do her justice, because her coat colour is really beautiful in person. I have a baby pic of her that is the only one I have that shows her true colour.
