[Baha Angel]

Earlier this month I had to leave home for a week due to some personal circumstances and I left my 3 year old Yorkie, Holly, home with my fiancé and our 1 year old baby boy, Shifu. Holly has very light spotting when she is on heat, so it is not his fault that he didn't notice it was her time. Well, they tied. I asked him a million times if he was sure, and he tells me yes, once, on the 17th of April. They are both very healthy and active dogs, free from genetic disorders and fully vaccinated for everything possible.

If someone experienced can please give me any advice on what I need to start doing right now, I would really appreciate it as this has been a very sad few days for me. I have read every article I can find on the internet, but I know I cannot read enough to prepare for the actual birth and aftercare of puppies. I would like to be as prepared as I possibly can. Also, is it common for dogs to take after only one tie?

Thank you.

Short version: 3 year old, 6 lb yorkie, tied with 4 lb, 8 days ago. I need advice on nutrition for her, as well as what to prepare for when whelping comes.
