Very well made chew bone!
Color: 1 PC-Beef-Red
Great durable, very well made chew bone! Our dog usually tears up all his toys within a few minutes or sometimes hours after he gets them. He’s had this bone for a few days and it’s still in one piece. Except for the rubber that’s in the middle, he chewed up in a couple of days. I would definitely buy more chew toys made by this company! Well worth the money!

The rubber middle is not durable, it lasted less than 3 hours.
Color: 1 PC-Beef-Red
I bought this as I have bully/husky puppies (9 months old) and a pitt/doberman (9 years old). They are heavy chewers and destroy everything. I saw a video of this toy. The woman said that her dog chewed on it for a while (about 2 hours or so) she showed the ends visibly chewed, which I expect but it was holding up. The rubber middle seemed to hold up to. I received this yesterday. I had to take it away from them last night as they were chewing the rubber middle off. They had it maybe 3 hours. I didn't give it a lower star score as I will just cut the rubber off and give it back to them. So I was disappointed in the rubber middle not being more durable but the hard plastic it's made from is the strong material they need.

Smaller than pictured but still a good choice for LG-XL dogs/power chewers!
Color: 3 PC-Beef-Red, Color: 3 PC-Beef-Red
Fantastic that these come in a 3 pack - I wish more chew toys did this! The base for these chew toys is pretty tough! The center & ends are hard enough to withstand both my bully mixes & my Irish wolfhound/Great Dane cross. They’re safe enough for even the largest power chewers! (With Supervision) my American Bully got the rubber spikes chewed off in under 20 minutes which is mildly disappointing but he’s a true powerhouse & master destroyer of all chews so I’m not that bent out of shape about it. I do wish they were as large as they appear in the ad pics but isn’t that the game we all play ordering offline anymore? 🤷🏻‍♀️ • Pro Tip: smear this toy in peanut butter (xylitol free!), wet food mixed into a slurry with water or bone broth + kibble/treats, yogurt, or even pumpkin puree and freeze for a few hours & relax while watching all the organic engagement your dog gets out of this toy!
