> Would it be best to leave her or bring her home and take her back in a few days
I often have bitches to stay, and, as it's such a small breed, I take them to bed with me. I've had bitches here that came on day 8, but took 10 days to be ready! I don't charge for keeping them, so time isn't an issue.
With my breed, I often find that the bitch is more eager to mate when staying here, than when being watched by the owner. I've only ever had problems with one bitch, and she wasn't used to living in the house, so pined for her kennel mates.
Bitches that live in the house, and are used to being fussed, don't seem to mind that it's me fussing them instead of their owners. Although I've had people say that their bitch just won't settle with a stranger, I have found them perfectly ok once the owner has left.
The stud dog owner has the benefit of the dogs instinct, and they are very good at knowing when the bitch is ready! :-)
I allow as many ties as the bitch will stand for. Once a day, so not alternate days like most.
