I went out to pay attention to my horses today, and when sassy came up to get some attention, she seemed to be breathing heavier than normal. No sweat and no obvious signs of pain.After leading her up to the barn, I took her temp and it came out at 99.8, so I wasn't too worried. her vitals and capillary refill seemed normal as well. What are some obvious signs a horse is getting heaves?? What else could this be? I have called the vet, but the only way she said she'd know it would be heaves is by coming out to inspect her. We scheduled an appt. for tues.
