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!

My dog loves it
Color: 1 PC-Beef-Red, Color: 1 PC-Beef-Red
The bone arrived today and my dog loves it. He is a very aggressive chewer and destroyed almost all his toys so far, even toys that were advertised for aggressive chewers unfortunately didn't held out long, the longest so far was a stuffy we couldn't find anymore and that one lasted him a few weeks but everything else lasted him an hour up to a few days max, even bones don't last him long so we have our hopes set on this bone to satisfy his chewing needs. I will update my review later on sturdiness, since we just got it and I can't review that yet but so far he loves it he has been chewing on it non stop, he already managed to get very small pieces of as shown in picture but with a regular bone he would've already been much much further. The bone is only 10 bucks so the value for money you get based on my experience so far is amazing! But also for this I will come back later to touch upon more. The size is good, our boy is a medium sized dog and this bone was advertised for medium to large size dogs and I thinks the size is just right for our boy . And there is definitely a beef flavor on it you can smell it but it doesn't smell bad it's a nice smell and not very strong but when he is chewing on it you smell it. I would based on my experience so far definitely recommend this bone but also on this I will touch back upon later if it's worth it in the long run. So far a very happy dog and owners here. Edit on May 8th (original review was on March 11th) He still hasn't managed to destroy it it's the first (cgew)toy he hasn't managed to destroy yet which is very impressive since he managed to destroy the even most toughest things we got for him in a week tops and bones within 1, 2 days tops, so we are very happy and pleased with this bone and will definitely get more later. He still enjoys chewing on it and leaves our things mostly alone for some reason he just likes stealing my things and chew on it lol. So 2 months later still stand by recommending this when your dog loves to chew and destroys everything he puts his mouth on.
