Hi all. Hope you are all keeping safe and well! I've had my most recent horse for 2 years and, for some reason, he has presented with an allergic reaction (I think!). Basically looks like urticaria (hives). We dropped out feed stuffs one at a time, to no avail! I then thought maybe I'm over rugging him - he's fully clipped, so I dropped him down a rug, still no better. I got the vet out the other day and he was adamant it was heat related and asked me to leave him without a rug totally - shock/horror!! This totally goes against the grain with me so we compromised and the horse is now in a little cooler rug at night and a 100g turn out in the field. To be fair, he is a 'hot' horse and still feels warm enough even in the cooler. We've been doing this for 2 days and, to be honest, no real difference. We feed haylage but it's cut off of our own field, exactly the same as last year, however, I am going to change from haylage to hay for a week or so - just to see.. He is bedded on shavings. So my question is, has anyone had experience of this before and how did you handle it?? If anyone has had experience of this and it was bedding related, what bedding would you recommend for a sensitive horse? Any help hugely appreciated.
