Would you breed this dog?

We have a 7 year old berner that isn’t registered. We never neutered him and he never showed dominance signs or aggression.

We said we would breed him if we found someone wanting to breed purebred Bernese (no doodles) and we are curious if that’s something people do with dogs not registered.

Dog is in perfect health, great temperament, loves everyone, kids, cats, dogs, etc
