* Double check that whelping supplies are ready
Post Partum
* Make sure each puppy gets some of the bitch's colostrum (first thin milk) within first 24 hours. Colostrum is loaded with antibodies to protect the puppies from disease. It also helps to condition their tummies to accepting food.
* Lochia (vaginal discharge) should be reddish to reddish-brown (green is okay on first day). If you see black discharge, contact your vet immediately!
* Within 5-6 hours of last puppy's birth, take bitch and puppies to vet for check up. The vet will ensure that the bitch hasn't retained any puppies or placentas and that the puppies are in good health. Ask your vet to check the puppies for cleft palates and what options are available. This vet visit is something that should not be skipped. If the bitch has retained a placenta or puppy, she could quickly develop a serious infection which could prove deadly.
