I wonder what's the statistical probability that a couple of dogs from the same kennel underwent the mutation?

Other factors will need to be looked at then. Was it just a plain muitation or could there have been other factors (mother's diet? genetics further back - maybe the recessive genes stay in a N/N dog but aren't seen?).
