There was a case of Snuffles at the fair this year, the infected animal was sent home. However when I got my animals home I realized one of my harlequins was showin signs: Sneezing, clear discharge, and matted fur on the inside of the front legs. I didn't think much of it that night so I took him out of the barn and decided to just check in the morning. This morning the discharge has changed to white and he definatly sounds stuffed up and sneezy. So, my conclusion is nothing other than snuffles.
I have checked all the other rabbits and no others are showing any signs.
I have some left over enrofloxacin, but no enough to thoroughly treat or prevent anyway.
The only injectable stuff I have is for horses. Probably not a good combination.
