Hi Jazzy... my apologies if I'm repeating previous posts. Haven't read thru all. You have a litter due from an unaltered rescue and need delivery information, if I read correctly. Sounds like you're already working on the whelping box. Make sure there are no abrupt corners, as a puppy can be wedged into them without mom knowing. Have a second smaller box with heat lamps ready. If for any reason this is an unusually large litter and a puppy is rejected, you'll want to have formula, a bottle and size appropriate nipples from your vet or feed store incase you have to feed a pup. Also several heating pads. You'll want to get a box of surgical gloves in case you have to assist in any way or break open a sack that mom may neglect. Have your vet explain this to you and show you how it's done. Know how to cut an umbilical cord, as well, incase mom has trouble. You may also want to pick up a muzzle. If for any reason things go wrong during delivery, a puppy is stuck or mom's in distress, you may have great difficulty getting her into car for emergency vet trip. She will not be herself during this period. You need to be able to safely handler her if you get in trouble. You're going to want to give mom added nutrional support during nursing. They can drop a lot of weight and added kibble often isn't enough. Talk to your vet about appropriate feeding program. Learn how to check mom for any signs of mastitis. Look this up on line and talk to your vet. It can be very painful for her, toxic to the puppies and you'll need to know what to do immediatly as far as treating the mom and how to care for puppies, should this happen. Make sure you have all of your ducks in a row, so you give mom and pups the best chance of a successful, stressfree delivery.
