Is it a proven fact that Chip is the sire? Or only guess work? Just because the pups might look like him doesn't make him the sire unless DNA was done?
Unless RMH does the DNA test, no one can say who the sire is. And all the more reason for Fanconi test to be done if the bitch is a Carrier. We have already seen test that show one thing and then the dog starts to spill. So, the DNA test gives a heads up, but still strip testing is necessary.
