The chew is very hard, so it does last a long time. My dog has been chewing it for a week and it’s worn down just a tiny bit.
Having said that, since it doesn’t give as much reward as a standard rawhide bone (which gets soft while chewing and you can rip it), my dog gets bored of it faster. I know it’s better for her health, but she doesn’t seem as excited with his one.
Also, sometimes it feels like the chew is so hard that she might chip her teeth.
