Agreed. Good for you, OP, for caring about the standard of care that mares bred to your stud and subsequently his offspring. However, unfortunately not everyone else has those same standards and that is their choice. Now if another stallion owner were to ASK why you had turned a breeding to that mare down (because they were told by the mare's owner, for example) then it would be up to you whether or not to say anything. If your opinion is not asked for in this instance I would not give it as it could come back to bite you and your stud in the butt.
If that mare were emaciated, on her last legs, had horrid conformation, no training and a nasty temperament the owner would still be able to find someone somewhere
with a stud that would breed her. Sadly some people care about the money and not much else, if at all.
