My dogs look forward to three things more than all others: When my husband gets out of work, Friday night ice cream, and BarkBox deliveries. Worth every penny, they love digging into it and I'm happy to keep their toy box fresh and interesting.
My husband started buying this at the suggestion of his doctor and I started using it, too. It certainly does the trick but it's still a bit strong for my (sensitive) tastes. We buy it at Walmart, it isn't expensive.
