I have been in very close quarters to a stud dog during a mating, with him breathing right in my face, as he had one front leg locked around my arm before turning in the tie, as I had been steadying the bitch, LOL
No I would not want such a dog used for stud purposes.
I have actually had other peoples stud dogs come to stay with me, to mate my or other peoples bitches. I think it is 6 different males now, and all have been perfect gentlemen with people coming and going, and the same has been true of studs I have visited, in my own breed and in dobermans in fact there is a lot more hands on with handling the mating pair and not a murmer..
