This Bites
Size: Large, Size: Large
We've happily used OxyFresh pet water additive for probably around 15 years. I love that product, so I figured their toys would be great too. Not so much. The concept seems good. This does feel like a heavy duty rubber and it feels like a sturdy construction, but in actuality, it did not hold up. Without a goal like food in it, my two dogs had 0 interest in this. It says you can put a treat in it. I wrestled to put a piece of kibble in the jaws of this toy, but that was tough and there isn't much room in there. That did pique their interest. Both my boys are about 50 lbs. One is a heavy chewer and the other is pretty gentle mouthed with toys. BOTH dogs were taking chunks out of this immediately. I must say that I'm really disappointed. If the rubber held up, this is a fantastic concept and seemed like it would work very well to clean teeth. Unfortunately for us, this was an expensive toy that began to fail within about 15 minutes of what seemed to be very average use. We'll be continuing to use a toothbrush instead.

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. 😉

Not indestructible, but pretty close!
Size: Yellow, Size: Yellow
I adopted a pit mix a little over a month ago, and so far he's managed to destroy every single toy he's had, including ones meant for aggressive chewers. He's a sucker for a good squeaky toy, and this had good reviews (and was affordable) so I decided to check it out.
He's had his corn for a week now, and surprisingly, it's still holding up pretty well - though there are some caveats to that.
My boy didn't even want to wait for me to take his corn out of the plastic bag, he too excited to get it. He went to town immediately, to the point where he was sitting in a puddle of his own drool after about an hour. He managed to squeak it (which I couldn't do myself), but still hasn't really gotten the hang of doing so - and the squeaker, when wet, does sound a little... Well, wet.
He managed to have bite marks in it within the first six hours. Within a day, there were tiny bits of yellow rubber starting to appear anywhere that he played with this toy. A week later and there are some decent sized chunks missing from the corn - some of which I've had to cut off when they got loose and I worried about him choking on them.
He loves his corn cob, and will likely get at least a few more weeks of play out of it before I have to toss it for his safety. I'm unsure of whether the squeaker is still functional, but he seems to love it whether or not it squeaks.
Overall, it's not a bad toy for most aggressive chewers, but it will not last forever. The rubber is as heavy as the regular red Kong toys, but it feels slightly softer, which might contribute to his ability to break off little pieces.
Make sure you keep an eye on your dog with this toy, or with any other, especially if they are chew goblins. But I'd definitely buy this toy again.
