I have a new doeling that is coughing. It's a very wet cough with no other symptoms. None. I'm going to give her Valbazen for lung worms, but I have a question on the dosage. In goatkeeping 101, the dosage says 1cc/10 lbs. On the bottle it says 3ml for a 75 lb goat. So do I give her 3cc or 7.5cc? Thanks for the help.
