Probably indestructible since your dog won't want to play with it.
Size: Yellow
Boring yellow and rubber chew toy with a weird smell. My dog was not impressed.

Great chew toy!
Size: Blue
Great chew toy that dogs love! The toy is hard but also soft for comfortable chewing. The plastic is lightweight and does not leave sticky residue. It is super easy to clean so won’t leave the toy smelling like stinky dog!

Truly Chew Proof (so far)
Size: Yellow
My dog loves this corn thing (he is 1 year old and roughly 50 lbs). He has gotten to be an aggressive chewer, but this has been one of the only toys that has kept up after long use (4 months since I bought it) and not been destroyed in minutes. There is a nice squeak to it, and I really have to press hard to get it going, but it is easy for him to do it. It is easy to clean, too, because it is rubber.
My only comment is for owner awareness: the description says "good for teeth and keeps them clean". This is false. I believe no dog toy or kibble will "clean" their teeth. You, the owner, just have to keep up with their oral hygiene through brushing. As for the other claims -- the training, weight management, and preventing chewing furniture -- again, use your best judgment. I did not purchase the toy for those claims. But as a durable chew toy, this yellow corn does the job and satisfies the natural instinct to chew.
Note: Some of the negative reviews for durability are for the alternative blue rubber bone, which I did not purchase.

The best chew, play and teeth cleaning toy
Size: Blue
I have a 24 lb medium australian labradoodle multigen. She loves to chew and nothing soothed her teething like this toy. It also cleans the adult teeth that came in. So win win. The squeakers didn't last but that was my fault for squeaking it to tire her out in play. We personally love this toy and will purchase it again when it wears out. So thanks for a great product. 😉
