Ok I figured that was the case but just needed to be sure.
Where are you getting that from? On the back of the bottle is says withdrawal is 7 days (for sheep) and no milk withdrawal has been established
So if the sheep isn't in milk yet it will be fine given the 7 to 17 days plus the time it takes for the colostrum to clear.
Actually sheep and goats clear things at a fairly similar rate, some things faster, some slower.
It's not approved for dairy sheep.
