In my naivety, I believe my horse has developed colic from eating Equea pellets and not enough hay. I was feeding pellets to get some weight back on her that she lost while I was away in May. I ran out of hay a week ago and didn't for one second think this would cause a problem as I had the pellets and she was getting an ice cream container full each day.
This afternoon, my poor girl was pawing the ground, hanging her head, laying down then getting up, standing really stiff in the back legs and breathing very fast. I called the vet and they advised a few things and a shot of bute, she has improved heaps since then. Her resp rate is down, she is much more relaxed and I have had her walking around periodically over the last few hours.
When I am observing her, she is not exhibiting any of the discomfort behaviours at all, she is quite rested though still breathing a bit faster than normal I think.
How long do I keep walking her for?
