Oh I would not present him with Facts.. I would dog nap the male and have him neutered...
If the female dogs look the same, have one spayed while the other one is at the vet then swap 'em back.
Unkie would hate me for sure.
While I agree with you that without titling/testing they should not breed these dogs. However, it is unlikely you will convince him of anything. Some people become more insistant the more you press them not to do something.
The one thing I can tell you from experience, the most dangerous health wise thing a non human female can do is to give birth. Most intact female animals are lost as part of the process mating, gestating, birthing and post partum care for the mother and the offspring.
