I'm just wondering how long I should allow for the Baytril to really make a big difference? Russell has been on it for 4 days (today is day 4), and as of yesterday evening he was still sneezing (wet), though overall he seems to be sneezing with a bit less frequency throughout the day. (He does still have sneezing "episodes", though, in which he'll sneeze several times in a row.) This morning I haven't heard any sneezes yet, but he does still sound a tiny bit congested. Should I continue to monitor for another couple of days before going back to the vet, or should I get an appointment soon?
