My huge SLO Roo sounded gurgly for lack of a better word. No discharge, sneezing, etc... I'm thinking respiratory infection. His eating and drinking seem okay. Well, I was tired o hearing him gurgle, so I tried Tylan 50. Intended to give 5 doses, but only made it through 4. I realized I hadn't heard him gurgle. Well, day 6 heard the gurlge. Gave the situation to God. Haven't heard him gurgle anymore and he even started mating (he's 6 months old now). Hope it doesn't make him sterile LOL
