Well worth the money!
Spent hundreds of dollars trying to find something that would last and something my 2 Pitties would not destroy in and hour and also something they would continue to use. Search is over..

Benebone... Best dog toy!!!!!
This is my dog's fave toy hands down. The Benebone brand is the only brand of bone I buy. My dog weighs 85 pounds and can really chew on a toy and these bones hold up well. They are the best in my opinion. They have several different flavors. He likes the bacon and PB. I love how Amazon has the "buy again" option. It just makes it so easy to repurchase your items. I usually buy the "Y" shape b/c it's easy for him to hold between his paws. BUT.... Sometimes I will buy the 4 pack if I need a good deal.

No more dental cleanings!!!
I have a 68lb Pitt mix who has consistently chewed on her bone since it was delivered over 4 years ago and she has just barely chewed the nubs down. This bone is indestructible and will keep your dog’s teeth clean. Daisy is 9 years old and does not have any tartar build up and has never had a dental cleaning. She just had her check up and vet said her teeth and gums look great!! Highly recommend this for your dog!

Worth the money!
I bought this for my silver lab. She’s a little over a year old and has recently became a very aggressive chewer. She absolutely love this thing! She has gnawed on it for hours so far and it’s still in decent shape. I’m interested to see how long it ends up lasting!

durable. interesting shape
Size: 9.5 inch
I like that chew bones come in a variety of shapes. This shape is currently not my dog's favorite but that is ok. She plays with it a bit. It is durable and she will get around to it sometimes.
