This is my favouriteee food toy. A lot of enrichment toys have smaller holes, or the foods all shoved in one central area, and being an impatient pup, I find this super frustrating and give up. BUT this toy is so much better. It still takes me a while to get the food out (especially when frozen), but the larger opening means I can continuously taste the food and feel like I'm making progress. And after I get the easier stuff, there's still a lot left inside the ring I can keep working for. Highly recommend this one!
