Won't purchase this one again.
Size: Large Triple
J.W. used to make a ring toy such as this, that was softer & thicker with a smaller black ring in the middle, that our dogs all, absolutely loved!!!!! But this one totally bores them to the point none of the dogs will pay it any attention! Please bring back the original 3 ring toy, that J.W. has now changed to just the one ring! I feel like they must have discontinued the toy with the 3 rings they used to sell, with the smaller black ring in the middle? I won't waist my $ on another one of these! Sadly, none of our 3 dogs will play with this specific toy at all! & I generally prefer to purchase J.W. brand toys for our dogs. But this toy doesn't attract them in anyway. It just sits around.

Great idea but didn't hold up!
Size: Large
My dog and I really enjoyed this as a tug toy to use where it kept my hands away from accidental nips. When we initially got it we let her play solo with it after our tug session and I noticed that she left little teeth puncture holes so we packed it away for awhile and exclusively used the other new toy we bought for her. After a few weeks we took this back out and, again, we loved it and this time I allowed her to play with it longer and although it was showing a lot of the little tooth marks it seemed to be holding up so I left it out with her. None seemed deep, just seemed like impressions from her teeth. We continued to enjoy it for about a week where she'd carry it over to us for tug sessions, loop it on our feet when we were sitting watching tv and chewing on it a bit. I'd look at it when we'd tug and, like I said above, it seemed to be holding up. After one session of tug when she took it off to chew on and I was watching some tv I checked on her after awhile and she had bitten through the black side and had chewed up into small pieces about a two inch section of it. Small, little hard bits were in a pile on the floor. She didn't just bite through, it had broken into small, little pieces and hopefully I was able to get all of them and she didn't swallow any! So if you want to get this exclusively as just a tug toy and not something for your dog to chew on and plan on putting it away after I think it will be okay for that and should last but if your dog is a serious chewer like ours is you may not want them to be allowed to chew on this. Seemed like it was going to last and then suddenly I was throwing away half of it and hoping she didn't eat any of the black bits. We still have the yellow side and will take that out for some tugging but no longer for her to play with freely!! She did tremendously love running around with this thing and would flip up the loose end and hook it on her face or our feet and was so cute to watch her!! Wish it had lasted!!

Name holds true.
Size: Large Triple
Just bought my second set of these.. first set lasted my healer almost 4 years and are still together but starting to split at the smaller seams so you can’t play as aggressive as my dog would like. We bought the second set and now she has her second wind! She loves tugging and I love knowing this toy will last a good while especially with an active dog!

My Aussie loves this bone!
This wishbone is so durable! My Australian shepherd is a big cheese and this is her go-to chew toy. It's a fave! She has spent HOURS chewing on this bone and it has held up super well. It has no smell but understand she can taste the flavor of it. I love having something she can chew on that is safe for her that she enjoys. Great value.

Durable, Great Value Dog Bone!
We’ve ordered several of these that have lasted for months, and my dogs are still working on them. Months. That alone feels like a small miracle. Normally, chews last about 10 minutes. Not this one. This thing is built like it trained for battle. It keeps them busy, satisfied, and focused on something that is actually meant to be chewed. And the best part? It’s way more affordable in the long run. Instead of constantly buying new toys, chews, or replacing destroyed shoes, this one just keeps going. Definitely worth every penny and then some. If you have determined chewers, this is the chew/bone you’ve been looking for.
