Tasha's finally getting some mileage out of her Mazee puzzle ball. It's a simple 3-D maze enclosed in a transparent sphere. You load in a few dog treats and watch her roll the thing around until a treat falls out. Repeat until depleted. Earlier, we made the mistake of putting in tiny treats that fell out way too easily. No challenge. The bone shaped biscuits had more staying power and kept her occupied for way longer.
Yup, a blur of motion she is, chasing her new toy across the floor. We won't have to worry about what she'll destroy next... for a while at least.
