Review on Durable Dog Treat Dispensing Toys For Aggressive Chewers - EastBlue Natural Rubber Ball Puzzle Toy, Almost Indestructible Fetch And Chase Game For Medium To Large Dogs. by Oscar Berry

This is very durable. My pup is a five month old Schnauzer/Blue Healer mix with lots of energy and curiosity. When goodies are added, this will keep her attention for a good period of time.If I pack it too tightly, sometimes she'll give up and that's that only con I've noted. You want it challenging, but not so hard to get the treats that they give up.I'm careful about what I use for filling. Little bits of meat or fish (no added salt) and some kibble or a little plain bread work well. I haven't tried freezing it yet, but plan to.Easy to clean by hand with dishwashing liquid and water. I can fit my finger with a thin rag or dishcloth. I rinse it very thoroughly.I'm about to order another one!Great item!
