Bests & Worsts Reviews from Amazon

I had no idea what to make of these when my wife ordered them. My dogs weren't entirely sure what to make of them either when we gave one to each. At first, they treated them like most every other treat we gave them. Gnawed on them for about 20 minutes and then left them alone. We had been hoping for longer play, but after 20 minutes of nonstop gnawing, neither of my dogs had made a real dent. We took them away for the night and brought them out the next night. That's when it started. After a night away, both dogs figured out what they needed to do to get something out of this nearly rock hard block of treat. Both need to hold it firmly and just keep scraping away. Both used them for almost an hour before I took them away because I was done listening to both dogs go at each one almost nonstop. Each block was still mostly the same length with a slight thinner edge where most of the chewing and gnawing had been going on. Each has probably had one block for 7 or more hours now and it's about half gone. They know exactly what it is when I bring the bag out now and both head to their separate corners to go to town on their treat. My Bernese has figured out how to snap small bits off the now small piece and takes those down with ease. I figure each remaining piece has about 2, maybe 3 more hours of play left before they are gone. So, we're getting somewhere in the 8-10 hour range of play per treat, per dog. That beats out the bones they chew clean in a hour and keeps them occupied for a lot longer than any toy or treat dispensing toy I've used. Definitely something we want to get again.
