Flimsy rope
Size: Large
This was definitely not sturdy enough for a large dog "up to 80 lbs" as stated. My 7 month old Shepherd puppy shredded the rope part in about 5 minutes. The chew stick is a hit but very small. Flimsy for the cost!

Fast Chew
Size: Medium
Didn’t last as long as I expected. My Frenchie chewed through it in record time. I will purchase another one to see if it’s the same as the one I received.

Great for chewers
Size: Large
I have bought these for the dogs (GSD/Husky/Golden) 4 mon-7yrs. All 4 dogs enjoy them and keeps the 2 puppies from chewing things they should not. Definitely worth the money for how long they have lasted as well. Have already ordered more.

Not as safe as it seems
Size: Xtra Large
I did like the look and sound of the all natural wood and coconut rope. However after 15 minutes of giving it to my dog there were rope fibers everywhere. Even though my research said coconut rope was ok for dogs in small amounts; my dog started throwing up. My cat also managed to get ahold of some of the strings and ended up choking. Even when I took the rope off and gave just the coffee wood stick; after just a few minutes of play my dog began coughing. This is just the experience that I had. All dogs are different. Just please don’t let your best friend play with it unsupervised

Do research
Size: Small
My pups love to shred things. This was a good toy for them to satisfy their need to shred things. My dogs are on the smaller side and I went with a small. I do encourage people to do their research and not leave this toy unsupervised. If your dog eats toys they shred this might not be a good toy for you. Coconut fiber can become impacted if too much is consumed. Unlike other reviewers I didn’t notice to much of a mess outside any other toy a dog might shred.
