I'm looking for some fun games to play with Zelda! She's very driven, very smart, and very high energy. I've tried hiding treats under Tupperware containers - figured that out in 3 minutes. Tried kibble in a muffin tin under tennis balls - that lasted 2 minutes. Fetch is fun, but she gets distracted outside and there's not enough room inside. Hit me with some ideas! She's 4 months old now.
