? about Line Breeding

Do any of yall know if NALC has a problem registering pups from line breeding? I have been looking for a big 70-80lb catahoula gyp to breed my bad boy to but have had no luck getting one. I just had a litter in december and decided to keep my favorite gyp from the litter to line breed. She is 4 months and is just about as big as her mom now and has feet as big as my 75lb male. the first time she laid eyes on a hog in the pin she was a bayin monster just as my male was at 4 months. i cant help but think she is a carbon copy of my male other than color. I plan on breeding if nalc doesnt have a big problem with it. what yall think?
