Major flaw
My dog liked this, but the charging port part is at the perfect position for dog teeth to catch on (there's a very large indented part with the on/off switch and that), so after only about two weeks of play, the usb C port is ruined and the toy can no longer be charged.
Larger dogs or very small dogs might have fewer issues. My dog is a miniature dachshund and he could pick up the toy by biting at that indented part.
(Also that "hello" is incredibly grating and if I forgot to turn off the toy would sound hours later, like in the middle of the night when we're sleeping and then my dog wakes up and freaks out.)

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.

Dog loves this
My dog absolutely loves the shape of these and will play with it for hours. The material is pretty durable too, though he is a big lab so over time chewed away the top nubs. Eventually tossed it at that point, but got great use out of it before. No bad smell and my pet really enjoys playing with it. It’s not too big either and is really easy to take with you on trips, etc. have bought multiple!
