My little bantam girl has that sickness where she's congested and her eye is bubbling. She's been that way for a while (maybe a week), sorry to say, before I was able to get her the meds. She's had one dose yesterday and one dose today, 1/4 cc IM. She's not looking any better yet. She sounds better, but she's still draining lots of fluid. She's in quarantine and is getting lots of good food to help put a little bit of weight back on her. How much longer should I continue the Tylan 50 after tomorrow's dosage?
