Lucky Lady, Please do not use oxytocin until you absolutely have to. In my experience and from what I have read, this hormone causes the uteris to contract more than it would normally and has the potential to cause brain damage in the pups. It can also decrease the pups heart beat causing a lack of blood flowing to the brain.
We have used the drug before but only as a last resort and to ensure that the last pup is born and the placenta has been discharged. In more cases than I want to remember, after injecting the drug, the last pup was still born.
I wish you luck and happy endings.
