A Jerky Treat (Beef Jerky in the 3DS version) is a piece of dried beef that can only be bought at the Pet Supply discount shop or in the BARC shop in the 3DS version. Like the Dog Biscuit and all other biscuits in the DS version, it is a first come first serve basis on who will eat the treat, since it is thrown at a dog rather than placed on the ground. In the 3DS version, you will have to indivually call a dog to give it a piece of Beef Jerky. The packet says "Dog Jerky".
DS: "This chewy dried beef makes for a delicious snack. (One Serving)"
3DS: "A favourite of dogs everywhere, but a little goes a long way."
