We use bitch season pants, but would NEVER trust them with a dog around. They 'can' get themselves out of them, so could the dog. I wouldn't just have her in a crate I'd have her in a separate room where he can't get into.
I don't keep dogs and bitches (though almost just did) for precisely the reason that I don't want accidents. I know that most people who do tend, as a rule, to have 2 doors between the dog and bitch. If it was me and I had kept a boy this time I'd have been sending him to 'camp' with a friend during that time.
