If your dog was eating placentas from the birth of baby goats, she likely will be ill. Check her gums..if they are pale and tacky, she is dehydrated. Check her temperature rectally..normal is 100-102.5..if its over 103, I am sorry to say that she really does need veterinary care but if you are on a farm, your herd health vet might be able to come out to treat her. For now, for supportive care, you can give her pedialyte (electrolyte solution) in small amounts and you can try offering her a bland diet of boiled chicken and rice. She will likely have diarrhea so keep the fluids in her. Other than that, there isn't much you can do other than supportive measures from home. I do not recommend any OTC medications for her at this point other than maybe a half of a Tums. Please let me know how you make out with her.
I sincerely XXXXX XXXXX could tell you whether or not your baby is going to be ok...but without a hands on along with bloodwork to find out exactly what is going on, the best thing you can do supportive care. It could even be pancreatitis from ingesting the placentas. You can read more about that here:

If she is not feeling better by tomorrow, do try to have her checked out. :)
