Pat what would your call half/half???
Inbreeding is mother to son, father to daughter, brother to sister
Line breeding is grandfather to granddaughter, grandmother to grandson
then halfbrother/halfsister is "inline" breeding lol
I know that inline doesnt exist but sounded good to me
I know many breeders do very well with inbreeding halfs and I havent heard of any major health issues
My mother inbred a lot, I have seen first hand, the good the bad and the ugly! Risky very very risky, but you can yield some beautiful pups if done right!
