Good luck on your new puppies! I bet you are nervous but you will do just fine!
I use nutra drops alot too. For new moms and pups. I use it during tail docking too. Immediately after its done.
I think Mardelins advice on Oxytotcn is a good suggestion too.
Ive been very fortunate and havent had a problem in the past with retained placenta. But I think it is a good habit to get into after birth.
I had a girl get extremely sick right after birth and I thought I would lose her. Fortunately she is a ball of fire and we didnt lose her, its been months ago. But if she would have been given oxytocin after the brith, an infection would have been prevented.
Be prepared for a 3 am delivery
