Long lasting
Size: Medium
My dogs love these and they last pretty long. I take them away when they get very small so I think they’re pretty safe.

Meant for bigger dogs than mine
Size: Small
I bought this for my 10 month old pup who’s a VERY aggressive chewer. I’m going to say this is made for a large, older (than mine) dog. She tried to chew a couple times but eventually just walked away from it when I offered it to her and she had only made a few scratches in it. If you have that bigger dog that’s an aggressive chewer, it would be a good value for your money and will keep the engagement high for a long time with its heavy duty quality.

Finally… a dog chew that doesn’t become a homemade prison shank
Size: Medium
My dog has a real talent: turning every “tough chew” into a sharp, weaponized shard that could star in an episode of Locked Up: Canine Edition. But THIS chew? Absolute game changer.
For the first time ever, I can relax—no splinters, no pointy edges, no fear he’s secretly crafting a shiv under the couch. Just happy, safe chewing that actually lasts longer than five minutes.
It’s durable, it’s safe, it keeps him busy, and I no longer feel like I’m living with a furry little inmate planning an escape.
Highly recommend if your dog chews like he’s got nothing but time.

Would buy again
Size: Small
Would have given 5 stars, but my dog was able to chew this down pretty quickly, so not the most durable. I do like that this is made with better material than other dog chews, so I would buy again.

Convenient Credit Card
This is an effortless and convenient way to purchase Amazon products. Unfortunately I am on it almost daily so the cash back feature is a plus.
