Very Hard & large toy
Size: Large, Style: Crinkle Fry
Harder and made from a different material than the other bark toys I have purchased. I think the others are nylon. Very durable just not as satisfying for the Cane Corso to chew as the more flexible toys. Was larger than I expected.

great for destructive chewers
Size: Large, Style: Crinkle Fry
it is so hard to find a dog toy that won't get destroyed within a week at most, esp with easily bored of toys dogs.
LUCKILY! i will say that both my goldens enjoy the french fry. i have an old picky dog and a young violet chewing dog. the only downside is i wish if i got 2 they wouldnt fight over the one the other has, but that's a review on my dogs more than anything lol
I was looking specifically for a barbox super chewer that is low on cost without losing quality of toy. 5/5 got exactly what i needed! that toy is STRONG and holding up great!!

Great toy for tough chewers. Just don't expect a miracle!
Flavor Name: Bacon, Size: X-Large
This is a great option for tough chewers, although if your dogs are anything like ours, there is a procedure to ANY new toy no matter how "tough". If I gave them this Nylabone and they went unsupervised day one, they would wreck it and it'd be in the trash within the hour. I say this to tell you, if you have a top 10 bite strength aggressive chewer, that you shouldn't expect a miracle.
If instead, I give it, take it away when they are working it too hard or being particularly destructive, and then give it back- and do this a few times for a week or so, then they'll chew it in a less aggressive fashion- they'll enjoy it and it lasts a long time. I don't know what it is about the first few days, but when something is "new" it has to be destroyed.
When it's been in the house a few days, they are rough but not as bad. Like the ones listed "virtually indestructible" will last 6 months as long as we have multiple around. It will show damage, there will be shrapnel in the carpet that will scratch up your feet, but it'll be worthy of play still. I consider 6 months in our house worthy of 5 stars.
This has been true for 2 Dobermans and a German Shepherd- and all of them have proven ability to destroy these products day 1 if I don't behave appropriately on introducing the new toy. If your dog wrecks these in the first 10 minutes, I'd say you probably need to work on supervising new toy play, and taking it away when they become to aggressive. This is a training issue, it can be done!

Durable, almost nondestructable, exelent guality bone.
Flavor Name: Bacon, Size: Medium, Flavor Name: Bacon, Size: Medium
We bought these bones about fifteen years ago and now I've been looking for them and was not able to find them. I've almost given up hope that they're still on the market. We finally found them yesterday. Since then we only have one small left and after a long time of gnawing on it, our two 50lb Labrador/German shepherd puppies are arguing over it. Even though they have other rubber and plastic toys that are supposed to help their teeth and gums, these two have taken a liking to this small size nylon bone and literally fought over it. The are aggressively protecting it like it would be real bone. I can't wait for the new two durable nylon bones to arrive. They are great for their teeth and gums.
Thank you for continuing to make them.

Super tough, great value, addictive toy for my dog.
Flavor Name: Bacon, Size: X-Large
My dog pit/Shepard mix, loves this bone, and I love it because she can't kill this one like all those other Kong toys. She had a smaller nylabone, she killed it but took about a year, this larger one, she won't be able too that soon. Hard expensive Kong things, wouldn't last a couple months with her. So now, 3/17/2026 its still going. One end is gone, but the green part and other bone end she's working on.
