>Her cage is jammed so that only the door is available for the boys to sniff.
I have seen what is left of a crate where a determined male has taken it apart to get at the bitch.
Certainly with my breed it would be next to impossible to live with a male in view of an in season bitch that he wasn't being mated to.
My latest litter the male was so keen on my girl, that when she was crated in the same room with him he was pushing a great big 48 inch crate all over the room with her in it, and this was after he had mated her twice!!! I thought he'd have heart failure, he was so worked up, and this is a male of 7.
In the end we had to keep her upstairs.
I have had studs stay with me, and they have been like Derby and Joan once the first mating had been achieved, able to be together under supervision, and would only mate the bitch when introduced first thing after morning pees..
