If the sire & dam are carriers then they should not have been bred from together. Clear to carrier is ok, clear to clear is best.TBH the breeder should have endorsed the KC registration with"Progeny not eligible for registration"You should then have signed a contract in which you agree to have the dog/bitch tested for VWD & if the result is a clear/carrier then the endorsement would be removedReally you should have researched the breed IMHO before buying a puppy & sought out a breeder who was endeavouring to reduce the incidence of VWD, by only breeding clear to clear ideally or clear to carrier, but never ever carrier to carrier. The dogs should also be hip scoredVWD is a life threatening condition & if it was my bitch that was a carrier I would not have bred from her at all & bought in another bitch who was from two clear parents.You have a 25% chance of your bitch being VWD affected, a 25 & chance of her being clear & a 50% chance of her being a carrier.You can look up health tests results on the KC site Also you could have looked up the health tests status hereShe's still breeding & has two litters of whippets & also breeds Dachshunds
HiWhippets would never have 13 pups in one litter, walk away I wouldVal
