Please advise. Picked up my goat herd yesterday. 5 does,probably pregnant,due in May. The gentleman I purchased them from told me it was time for their CDandT injection. I called my vet on my way home, he was about to close but he reccommended covinex 8, which I said "ok, sure". He left it for me outside all packed in a cooler. My question is since they were getting cdt before, how much do I give of this covinex 8 initially? I don't want to give too much and make them sick, give to little and not do any good or hurt their babies. The gentleman I bought them from said the cdt was good for the babies but what about the covinex 8. When I talked to the vet my cell phone was not great to say the least and we didn't discuss all these possiblities. Thanks for all your past comments too.
