I have an American Bulldog that would chew a brick if he didn’t have an alternative lying around. They won’t last forever (nothing does) but we’ve had two of these over the course of a year and for him that is nothing short of a miracle. And that is daily chewing like it’s his job. I highly recommend the Acornucopia for aggressive chewers with jaws like hyenas…so it’s probably great for your dog too.

Great Product!

Size: 5.75 inch (Pack of 1)

My dog is a chewer! She can chew through most chew toys in a day. This has been a lifesaver! She chews on it but has not been able to get any pieces off of it. It is Durable and she loves it! This is a great item. I intend to buy more like this. It is a great product!

Amazing toy for large dog breeds!

Size: 9.5 inch (Pack of 1), Size: 9.5 inch (Pack of 1)

My puppy Rottweiler loves this toy! Withstands her heavy chewing and really seems to soothe her! It’s very loud against the floor. She struggled a bit at first with picking it up but now it’s no problem. Highly recommend for big dogs

My puppy's favorite stick, high quality

Size: 5.75 inch (Pack of 1)

Perfect quality chew toy for my dachshund puppy. She will spend several minutes everyday chewing on this. It is the perfect size for her small mouth and it doesn't show signs of wear like most sticks do.

Great buy would highly suggest for dogs that love to chew. I bout a large one for our 5 year old Husky and a medium one for our 11 week old puppy. Both are very intrigued by them and the puppy loves playing fetch with it. The only complaint I have is the size difference between the large and the small. I know measurements were given but the medium looks more like a very small stick. If you have a larger go with the Large size. Medium would really only work for smaller size dogs and pups
