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.

Not Suitable for Power Chewers

Size: Large

Coconut fiber toys aren’t ideal for heavy chewers. They shred easily, can be swallowed, and may cause choking or intestinal blockages. The coffee wood is a safe durable product and loved but my dogs. I wish I would have done more research before buying the coconut fibers chew.

Dogs love them, not long lasting

Size: Large

Our dogs ignored the toy for the first day or two, then immediately became obsessed, working on them for hours at a time. They did come with big cracks/splits in them. The first one it wasn’t a big deal, but the dogs pulled large slivers and chunks off the second within minutes of using it. Also, gigantic mess around the house, like letting them play with a stick. I plan to continue to buy since the dogs love them but I do think they are a bit expensive given the quality variations.

Durable, good value, clean, natural

Size: Small, Size: Small

I bought this coffee wood toy with the coconut rope for my heavy chewer (Jack Russell Terrier) a couple of years ago. I was pretty skeptical that it would last very long and be a toy that she would enjoy. This is one of her favorite toys, it's lasted for 2+ years, and it's not gross after so much use. This dog shredded everything in sight when she was a puppy, so it was important to find her lots of different hard toys. I bought another coffee wood toy with no rope, and she doesn't care for it as much. We might have to drill a hole and add a coconut rope when this one get's too small. I have not had an issue with the coconut fibers or wood pulp, though I'm sure she's ingesting some. I have had to take away many hard toys that she managed to chew off large bits or I felt like she was eating bits of plastic, but this one has been safe for her. She was already an adult dog when I got her this toy, so I cannot vouch for how it would work for a puppy, but I suspect that it would have been a toy that I would only let her have under supervision when she was a puppy. I like that it is made from natural materials.

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!
