How do you get your foal to lay down on petz horsez 2 ds?

Unfortunately, there's no specific command or interaction in Petz Horsez 2 DS that makes your foal lie down. The game focuses on basic care and training, and lying down is not a feature.

However, you can try the following to encourage your foal to rest:

* Feed your foal: A well-fed foal might be more likely to rest.

* Put it in its stable: Foals often sleep in their stalls. This might encourage it to lie down.

* Play with it gently: Sometimes, after playing, a foal might get tired and lie down.

Keep in mind that the game's AI is limited, and you may not be able to directly force your foal to lie down.
