Rent-a-Horse

"There are rental horses available at MacDonald's [sic] ranch. You will need to install a Stable in your yard if you plan to have your own mounts."

The Rent-a-Horse is a service McDonald offers, conveniently located near McD's Jumpin' Livestock and Sophie's Ranch. After fixing his stable, the player can buy or rent horses from it.

Horses
Horses allow much faster movement than walking or sprinting, though they cannot do sharp turns. While the player is dismounted, the horse will follow the player around unless told to stay or return to the player's Stable. Owned mounts will stay in the Stable until the player rides them for the first time that day, whereas the rental horse will follow the player around as soon as they leave their house.

The rental horse can be rented without owning a Stable, and costs 500 for seven days. After the lease expires, McDonald will leave a note in the player's mailbox in the morning to let them know he took his horse back.

The rented horse starts with its stats maxed out, while purchased horses must be trained to their full potential. However, the stats of either of the purchased horses can eventually exceed the stats of the rented horse, and the white horse also has higher maximum stats than the brown horse.

The amounts each stat is already trained to when the player initially rents or buys a horse are below:
