The Jack Russell Book (Japanese: ジャックラッセルの本 Jack Russel Book) is an item that falls under the category of "Etc." in Nintendogs. It is one of the rarest items that can be found on walks, and getting the book allows the player to buy Jack Russell Terriers at the Kennel. Despite this item's rarity, it only sells for $3.60 at the Secondhand Shop.
This item appears to be a book relating to Jack Russell Terriers, but it cannot be opened. It can be thrown across the room and many dogs will play with the book rather than being scared of it.
