What brilliant news! I am sure there are people here that will help you - i can name a few!!!

I haven't bred but i know that some breeds have a liklihood on the number of days etc and also i can;t answer the food question - only to confirm that they go onto pup food but what you are doing may be fine also - cav has just had pups, talk to tashi and Rach too. I hope that helps - don't forget to keep us posted!!

Pics a MUST!
