I found out today that my dad's gelding PintoBean (15.1hh 1,050 pound gelding) mounted a mare today (probably 11 hands, and very very little). I want to know if that can really hurt her, because I want to tell my dad, but my dad doesn't normally listen unless there is a reason other than "Dad that can HURT HER". But she isn't our mare, she is someone else's and I don't want her or Bean to get hurt.
What can happen to the mare? Can she get infections or anything?
