Yeah. She was fine while the shot was working and at least it didn't wear off quickly. If it is sweet itch there is no way for us to eliminate the gnats other than topical bug repellent. We are in south ga so it is basically a swamp here. The goats have hoop shelters and live in a huge pasture with woods.Aw, that’s too bad, I was so glad for you that your May was doing good this year. I hope another shot helps her out.
