I'm not familiar with CA but if you're willing for the pup to travel I know of one whom is reputable & has beautiful stock.What a beautiful dog.
I had a ridgeback named Loudog who passed away at 14 in 2010. I am going to be looking for another ridgeback pup here soon. Awesome breed. If you know of any breeders in Ca please pm me thanks.
My son has 3 of them.
PM if you'd like info.
