My 6 year old QH mare has had a runny nose since I got her about 3 months ago. I did some research and found that it was not a problem as long as it is clear, which it was. She was eating grass in the pasture until about 3 weeks ago when I gave her a round bail alternating pens ever 2 days from grass to bail. She has developed a small cough since she started on the bail (only when she is being worked).
Yesterday her runny nose was green. I wiped it (ew) and it didn't occure again throughout the night but I wasn't working her hard. Should I be concerned? I don't want to call out a vet if it'll just pass on its own but I am worried for her. She was de-wormed in July as I didn't know when her last de-worming was. She only got about half a dose though, don't know if that might be the reason for the colour change!
I'll be moving her Oct 1st to a boarding facility with 25 horses so I don't want her to be sick and susceptible to other illnesses because of her runny nose.
Thanks in advance :)
