I took in two pregnant dogs and the first dog had her litter of 4 last Sunday where 2 did not make it but the other two are doing good and she is a great mom. The other dog had her puppies today 1 was deformed and didn't make it the other one is doing good but when she had the puppies she did not try to get them out of the sack or chew the cord. Infact she would run around and roll around while the puppies was attached so I had to step in and get them out of the sack and cut the cord. She was in awful pain and I tried to help and calm her but she ran rolled and screamed. I called the vet and the vet told me not to bring her in during active labor. When she calmed down I tried several times to offer her the puppy and she had zero interest in the puppy. The puppy was cold and crying and I tried to keep it warm but the mother would not take her. I had no choice but to introduce the puppy to the other mother who took right to cleaning it and even chewed off the cord because I left it too long. She warmed the puppy and its feeding her. Should I give the real mom another chance once she recovers or keep it with the other mom.
