Answer
Hi Mary

If it was me, I would wait until after the female had her pups and built up her system before I gave her anything.  Worms can lay dormant in the muscle and when a female becomes pregnant they detach.

An all dewormer like Drontel is the best.  

Some females will ovulate later, so if she's receptive to a male, you may have caught her too early.
