Need help finding title

It was about two horses and had a semi unrealistic style. There was a brown horse who was stubborn and tough who hates humans and a shy blonde horse who keeps following him. A storm hit their farm I think and the brown horse managed to escape but the blonde followed him. The whole thing is about them getting back to a meadow where the brown horse came from I'm pretty sure. Really wanted to reread it again, I think it was a canvas story. Any help is appreciated
