Hi,
My horse has always been quite sensitive to dust and often coughs if he is fed hay. He's lived in a lot in his life but now with me he is out 24/7 and will stay out all winter. He has a field shelter which he has free access to and will be fed haylage all winter inside and out so he can choose where he stands. Last winter he only coughed when fed hay, and it cleared up as soon as I gave him haylage again.
Unfortunately about 6 weeks ago he started coughing a little, it got worse and he got quite lacklustre, so we had the vet, who gave him ventipulmin, which really helped, however when that finished the cough came right back. The vet gave me another tub of ventipulmin which he finished on Saturday. Last night he started coughing again, quite badly. He doesn't cough at rest, but as soon as you move up into trot he starts coughing and can't trot for long before he is puffed. The vet is coming out on Friday to to an endoscope and trach wash. I am quite baffled really as my horse lives out 24/7 and at the moment we have fairly good grazing so he isn't having any haylage, just grass. I suppose it could be a pollen allergy. He really isn't very happy though.
Anyone else experienced anything like this? What was the outcome? The vet was talking about steroids and inhalers which makes me feel so sad for my horse.
