Hello everyone, hoping for some help. I have a 15 year old QH mare that I moved from NW Arkansas to East Texas. She was healthy in Arkansas but is getting SEVERE seasonal allergies down here in East Texas about mid summer when the grasses come on good. Last year the coughing got so bad I took her to Texas A&M Vet Hospital. They confirmed the severe seasonal allergies, did a trachea wash and put her on steroids; advised me to keep her off the grass, stalled with her head in a hay bag. Sure this might work but she can not be stalled up all the time. I asked about allergy shots and they told me they really were not that affective on horses...as anyone else run into this? Anyone giving allergy shots? Are they working??
