He loves it! It will probably be destroyed soon though...
Size: For Medium Dog, Color: Green, Size: For Medium Dog, Color: Green
Update! This toy has definitely withstood my boy's daily chewing! It's lost some pieces for sure, but overall it's holding up and I'm very happy about it. The only downside is the squeaker is rather difficult to get to make noise. Will still definitely invest in another when this one finally goes.
Original review: I bought this for my handsome pitbull/boxer mix -- the boy loves to chew toys up! He's an aggressive chewer and he was bored with the current toys we had.
This toy is advertised for chewers, and I imagine if my boy wasn't such a great chewer, it would be amazing! We've had it three days now and he's already gotten a few big chunks off of it. It is definitely entertaining him though! He loves it and he seems like he's chewed himself into a daze. There is a squeaker in the bottom that seems difficult for him to get to so it doesn't squeak often -- when it does though he freaks and it's hilarious.
Overall I'm very happy with this purchase. My boy is a very aggressive chewer and I know pretty much anything we get him will be destroyed soon after he gets it. With how much he is enjoying this toy, I will be buying it again for him.

Outstanding Chew Toy
Size: For Large Dog, Color: Green
My dog is beyond an aggressive chewer. Toys are in pieces in minutes no matter what the manufacturer says. The squeaker? Forget it gone immediately. She has had this toy for two days and not only is it intact but she hasn’t been able to remove the squeaker!! Great product!!!

Be careful. Prices come off
Size: For Medium Dog, Color: Grassgreen
My dog loves it but it does come apart. He’s not a dog that destroys things but he bit prices off of it.

Heavy duty
Size: For Medium Dog, Color: Green, Size: For Medium Dog, Color: Green
I just unboxed this so I will update if my opinion changes. I bought the medium dog toy, it’s a a great size, perfect for my 110 pound lab and my 60 pound pit terrier mix. It’s heavy duty so I don’t see this being torn apart anytime soon, it has a slight mint scent (mostly rubber). As of right now, I can confidently say that I see myself buying more from this brand. Hopefully it helps with their stinky breath, if not then at least it’s a fun toy for the pups.
Update: after over a month of play I can say it’s still going pretty strong. My dog did manage to damage it a bit but if you have dogs who are rough on their toys, this is a good option. I was also surprised to find out that there is a squeaker in the base of it, the pups have to bite really hard in order to hear it, heavy duty toy.
I will say one of the only downsides is that it doesn’t seem too appealing to my pups. If there are other toys around they’ll go for the other toys but occasionally will pick this. I still recommend it. Has been lasting us awhile (I have 3 pups).

Dog ends up eating plastic ends
Size: For Medium Dog, Color: Grassgreen
At first I thought this would be a great toy but in reality the design doesn’t make sense. The little pieces ‘pricks’ of the cactus get chewed off and swallowed by the dog. So you’re essentially feeding them plastic.
