Name: Acorn. symptoms: runny nose possibly slight chest congestion makes a strange 'burpy' noise every once in awhile that might be a cough? like 'kwumpf'. short little sound. we took her inside starting two days ago to be warmer. she's on Sulmet. We have access to Duramycin... perhaps we should switch to this? the day we took her inside, she seemed extremely lethargic. i gave her eyedropper drops of electrolyte/sugar water all day, and she seems MUCH better... but now has that cough-like sound going on. her runny nose hasn't gone away after 2 days on sulmet, and the cough sound only just started in force tonight. Please advise. She's an absolute sweetheart.
