How do nitendogs hug?

In Nintendogs, dogs can hug by interacting with the player through the touchscreen or microphone on the Nintendo DS. Players can pet, scratch, or call their dog, which can prompt affectionate responses like nuzzling or leaning against the screen. These interactions create a bond, and the dogs may express their affection through animations that resemble hugging. The game's design emphasizes nurturing and connection, allowing players to experience a virtual bond with their pets.
