Fast Travel to a city, then check its stables. If it's not their, check Wynon Priory. If not there, he might be dead. In my game, it sometimes hangs out in the stables in Cloud Ruler Temple, check there too.
If nowhere, there is a mod available with the same name as this topic that puts a quest marker on your horse, so you'll never lose it.
