Very durable!
Color: Blue T-Bone, Size: 1 Count
Great product! Dogs love it and very durable. I had been buying the nylon bones in pack of 3, but my 2 dogs would chew them up in no time, and I was buying the aggressive chewer bones. Bought 2 of these, dogs loved it, so I bought another one. Have had these for about 2- 2 1/2 months and still holding up just fine. And the price is great! Would definitely recommend!

Great for chewing but very sharp and mangled in a few days
Color: Blue Gator, Size: 1 Count, Color: Blue Gator, Size: 1 Count
I thought this was a fantastic idea having baking soda added for fresh clean teeth while enjoying a new toy. I wanted to review 2 main things about this. First, if my dog enjoyed this toy. That answer would be yes absolutely! She is chewing it as I’m writing this right now. She can spend a good amount of time chewing away on this and it keeps her busy without having to use a rawhide treat which we only try to use if we re going to be gone for longer then 4 hours. The kids love playing fetch with her and she stays engaged the whole time. It is very heavy and when being thrown can become a weapon so I always supervise! Last, the durability of the toy. So it is durable but not completely. As you can see the toy got very sharp where she has been chewing it and I’ve even noticed a little blood on it which means it’s cutting her gums. It wasn’t a large enough amount for me to take it away. It is still almost the exact same size but maybe after a month I will re edit this for more accurate on durability since it’s only been about a week that she has gotten it. Overall, I would recommend this toy it’s a great price and keeps her attention a lot more then other toys I spent twice the amount of money on!

Too Hard
Color: Blue T-Bone, Size: 1 Count
I have a pit puppy, 20 lbs, who loves to chew. She's huge for her age, and I wanted to get her a new toy. I bought two different toys, hoping she would like one. The other toy was a hit, they both jumped at it and were excited about it, probably because it had rawhide rings that went with it. This one was immediately thrown to the side, even though my pit loves to chew on non edible toys. I think this one was just too hard, because both her, and my Chihuahua-Jack Russell, weren't interested. It didn't have any smell to attract them, which is why I bought it, because they love peanut butter stuff. I'm not going to go as far as to lick it and taste it... I'm pretty sure it won't taste like peanut butter, either. I feel so bad for my little pittie, she's just sitting here with a sad look on her face because my other dog stole the fun chew toy. I've immediately ordered another of one of those so they both have one, but I've just money wasted on this one. It's probably better they don't like it, I'd be worried about them breaking their teeth. I know it's supposed to be for power chewers, but it has no give whatsoever, just extremely hard, shiny plastic. It's useless, unless you're planning on filing it into a point and making a prison shank. Maybe you can leave it in front of the fridge for your SO to step on in the middle of the night when he goes to steal your almond milk. I'll figure out some way to use it. I did dip it into my boyfriend's peanut butter jar to let my puppy lick it, but I can do that with a spoon. I wanted her to feel like she got something, maybe my other dog will let her have a turn with the fun toy after awhile. That's the only reason I gave it 3 stars. You can dip it in peanut butter and I was being generous.
