Bo is due June 19th. X-rays show three pups (see pic - aren't they cute already...?!

). I know the first few days are crucial...
And I also know I'll need a whelping box. Unfortunately, I don't have a room I can keep heated at 80°. Is it better to get a heat lamp or a heating pad to put under the box?
I'll get new surgical scissors, dental floss, lots of clean towels and blankets, whelping pads, a bulb syringe, a digital scale, rubbing alcohol, betadine.
What else will I need?
Bo and her little ones will be very grateful for all your advice and suggestions.
Linda
