I would recommend.
Flavor Name: Peanut Butter, Size: 2.19 Pound (Pack of 1)
I was given a bag of these as a gift, and I decided to rebuy because my puppy loved them so much. But after eating two out of this big bag she doesn't like them anymore. But my pup can be very picky. An adult dog can wipe one of these out really quickly, so it might be something you want to watch if your dog is a vigorous chewer. But I never saw a piece come off that was big enough for my dog to choke on. My sister's dog loves them, so I think my puppy is just spoiled and super picky.

"Busy" is right.
Flavor Name: Peanut Butter, Size: 2.19 Pound (Pack of 1)
These are plenty big, so your dog will have a good ol' time with it. Probably won't do much else till it's gone. Not sure "chew" is an accurate description, it's more of a gnawing and slobbering kind of process. Drool seems to soften them up. Don't give them one on the bed or couch. They are hard, resilient, and rather dense, but not crunchy; they don't break up like a biscuit would. And the center is sort of like a very stiff taffy. But it took me way more licks than a Tootsie Roll Tootsie Pop, I can tell you. Our little dogs tackled one that I cut in half, and they did pretty well. But they really are too big for small dogs.

My god loves his new chew bone 😍
My dog loves this chew bone, he chewed on it daily since I gave it to him. It's good value for money, pretty hard, lasted about a month & a half. Good size bone for a medium sized dog

Long lasting bone for aggressive chewers!

Best thing for boredom
My dog loves the Benebone especially when he is bored. He loves the chicken one the best. When the edges start to splinter or get rough, we get him a new one.
