Great Bone for aggressive chewers but watch the wear & tear
I’m extremely happy I found Benebone Bacon Flavor Large Wishbone for my puppy who is an aggressive chewer. As the packaging reads this is a durable nylon. My puppy chewed the bone down to what you see in the picture within 3 days. It’s easy for him to handle. He loves the bacon flavor. He immediately took to it as soon as I gave it to him & off he went to work. I did check with my Veterinarian first to inquire if this was a safe bone & she assured me it was. She did advise to be aware of the wear & tear on the bone & toss when I felt it was time. I honestly wouldn’t of known when. I’m happy I took the time to read the inside of the packaging this bone came in. It referred me to the benebone website which showed pictures of bones-which I attached- that reflect the wear & tear & when it’s time to toss. There are the 3 categories of “Light Wear,” Moderate Wear“ & “Heavy Wear.” You’ll see the written description next to each. This I found very helpful, therefore I wanted to include it in my review, in hope of helping you. By the looks of my current bone it’s in between moderate & heavy wear. The large is costly, I feel, but it 100% occupies my puppy. It’s his favorite “toy.” I’ve only had small shavings come off since he’s chewed it. Nothing major to clean off the couch where he lays. Stuffed toys are a thing of the past now. I’ll continue to buy once it’s time to toss this bone because he loves it so much. I also love that Benebone is Made in the U.S.A.! I definitely recommend! A heads up! If you click on their store on the main page of this bone you’ll find other shapes of the nylon bone as this one. This Benebone won’t disappoint. Take the time to read the packaging. It’s informative & cool!

Very durable and long-lasting, great for strong chewers, gets rid of plaque in older dogs
I have a seven-year-old golden retriever who was never a strong chewer, she liked gnawing on toys and dental “bones” and destroyed shoes and a carpet when she was a puppy but it was never her favorite activity. Then I adopted two puppies of indeterminate breed, but likely Plott Hound and Lab, and they are aggressive chewers and want to chew on everything. I tried all kinds of teething things, as teething seemed to bother them more than any of the other four dogs I’ve had, and all were destroyed quickly, like they were treats instead of supposedly “long-lasting” chew bones. I tried these bones after I happened upon them on Amazon, and I could not be happier. My dogs contentedly gnaw on these for extended periods of time, obviously in heaven as they do so, and sometimes it’s the only way I have time to get anything done. When they were teething these definitely helped them with teething pain, and now they still want to chew on them every day. They can hold them easily and sometimes the puppies even share a bone due to the unique shape. My Golden had lots of plaque and nasty buildup on her teeth and was headed for needing dental cleanings under anesthesia, but now her teeth are sparkling white without a speck of plaque thanks to these. The bones have worn down over the course of eight weeks, but very gradually and not ever in pieces. Yes, the ends become prickly and are definitely not fun to step on, but I don’t let them chew on them outside to reduce them collecting dirt and rinse them every few days to get rid of whatever is on there. I have watched carefully for any signs of irritation in my dogs’ mouths or teeth issues, and have never seen any blood on the bones even after my dogs have determinedly chewed on them for an hour. They LOVE them, and because they are the only bones I have found that last longer than five minutes for my aggressive chewers, hold their attention for an extended period of time, and get rid of all the plaque on my older dog’s teeth, I HIGHLY recommend them.

I love this and so does my dog
I got one of these, to try out on my super chewer pit mix, back in early April, it's now the end of June and she's still chewing it every day, almost all day! It has gotten smaller as she's chewed it but it's not broken or splintered or hurt her teeth! Just make sure to get the right size for the dog. Small dogs maybe the smaller ones but a big girl like mine needs the large or bigger. Idk if she gives a darn about the taste or smell of it but she loves chewing on it, and hasn't felt the need to chew my shoes or wtfe since she got this. I like it so much I got more for my friend who also has a few super chewers and she gives good reports on them too. Her chewer dogs have stopped destroying her house in favor of these chews. Just try not to step on them in the dark, cause that s#!t hurts, BAD! Lol especially if you step on the chewed parts, where its rougher. The attached Pic is showing how badly she's chewed it in almost 4 months! The chewing calms her anxiety and gives her something to focus on when she's too excited, especially late at night. I will be getting more of these for her. even thinking about trying other shapes to see if they hold up as well as the wishbone shape does. She's an adult dog so idk if these would be OK for puppies, as it might Crack their teeth.
