I am soon moving into a hotter temperature state and I want to know how to get my horse prepared for it, Do you have any feeds suggestions and ideas ?

Thanks, yes I clip my horse.
This definitely helps a lot :)

Hello Brittany,

Have you considered clipping your horse?
Then I think you shouldn't change his diet but when you'll be there try to pay attention to how much water he drinks to be sure he drinks enough water. You can also give him some electrolytes to help him keeping hydrated.

Good luck, hope it helps you :)
