I was going to phone the BHS tomorrow to just get clarity. I'm still on the fence about contacting the breeder. I spoke to BAPSH today, and they said that we can ID baby daddy if breeder plays ball. Obviously that means collecting samples off the suspect randy colts (ANCCE already have Dad's DNA on file). If I do that, Caso can be registered in the main BAPSH studbook. If I don't, he can still be registered but in something called appendix B.
