From what I recall horses require:
- Training on how to ride a horse
- Suitable land area for the horse to graze
- A stable and land to build a stable
- Food and water
- Potential vet bills
- Regular health checkup bills
- Potential medicine bills
- Horse shoes and replacement horse shoes
- Supplements for dietary needs horses can’t easily get from their food
- Horseriding gear
Keep in mind that I’m not involved with horses at all, this is just what I’ve learned with my exposure to them on the Internet
