When I first got Sandie about 5 weeks ago, I noticed that her eyes were bloodshot...the vet who checked her over didn't mention it so I thought it was perhaps from the stress of the move or something. But 5 weeks later, they are still bloodshot pretty much all of the time.
I asked the barn manager if he's ever seen her sleeping in her stall, and he said yes he has, so I don't think it's that she isn't getting enough sleep, her sleep patterns seem to be normal.
What else could cause both of a horse's eyes to be bloodshot??
