Hi Jen,
Do you know much about the size of Shadow's line? If his parents and others are small it should be ok to use him, but if not you might want to consider another male. But use the same idea with the stud if you use one - if he's parents and others were large you might want to choose another.
I would keep the two seperated until the 10th day and also when you're not around if you're not already
Most people find it best to hold the female and have the male come over. Make sure when he starts to come out that he's inside her or pull him off her.
Good luck
