I really can't draw horses so I look for guidelines to draw one

Anyways...

One day, Leo was on a road trip with his family, when his little brother found an injured horse, sitting on a field alone. His little brother begged his dad to check on the horse, and he agreed.

They took the horse home and treated its injuries. Leo was the one who stayed by the horse's side most of the time, so they formed a close bond. His little brother named the horse Sadie.
