Hello Ian,
Generally you shouldn't start house breaking Peggy until she is 10 to 12 weeks old and totally acclimated to your home.
I recently published an article at ezine.com on Beagle housebreaking:
Beagle Training - How To Housebreak Your Beagle For Good!
I recommend crate training for housebreaking and you can read all about that on my website:
