“I got this for my puppy after we moved house to keep her occupied during the day. When I watch her play with it she rolls it around and chases it sweeping up the treats as she goes.
Each day now before going to work I stuff it full of (healthy) treats. At the end of the day they are pretty much all gone - a good sign I reckon.
Some of the other similar toys are too hard for her to get the treats out - but not this one.”
