I posted about a friends bitch who was mated accidentally on day 19 of her season after planned matings on day 12 -14 . The bitch has had her puppies now. She had 4 healthy puppies born on day 59 from the first mating which was day 52 from the accidental mating. As all the puppies were obviously mature and viable then thankfully it seems tha accidental mating did not result in puppies.
