My puppy loves it!
Flavor Name: Variety, Size: 3 Count (Pack of 1)
My puppy absolutely loved these chews! They kept them busy for a good amount of time and helped with chewing during the teething stage. The treats have a nice texture that’s softer than regular bones, so they’re great for puppies and small dogs.
The roast beef, apple, and bacon flavors were a huge hit, and I like that they’re made with more natural ingredients compared to many other puppy treats. They don’t leave a huge mess, and the small size is perfect for petite puppies. Great option for rewarding and keeping little pups entertained.

Puppy is in heaven!
Flavor Name: Variety, Size: 3 Count (Pack of 1)
This is our second order! My newborn pup loves these things and they last a good long time! I do not feel there’s a choke hazard like with rawhides because these bones kind of disintegrate like an edible substance and don’t make a mess. Will keep on the auto ship!

Great for puppies
Flavor Name: Variety, Size: 3 Count (Pack of 1)
My 8 week old puppy loves these bones! They did keep him busy but I wish they lasted him a little longer! With that being said, I would still purchase these again.

HOW WE USE THEM SAFELY
Flavor Name: Variety, Size: 3 Count (Pack of 1), Flavor Name: Variety, Size: 3 Count (Pack of 1)
Our eight week old puppy was getting hard to hold without her trying to chew your fingers off. My husband found these bones at a pet store. My little puppy and my five year-old Yorkie both love them so much that I knew we were going to need more right away. I ordered three packs from Amazon. As I was ordering them, I was reading the reviews and I always head straight to the one star reviews first. After seeing how many people had problems with their dogs, choking or pieces of the bones breaking off it made me a little nervous. So instead of letting either dog just run off and chew on the bone alone, whenever I’m just sitting doing nothing anyway, I will hold the bone and the dog in my lap and let them chew away so that they are not unsupervised. It has worked great for both my five-year-old Yorkie and my little eight week old pup! It has really helped my pup not chew my fingers as well! I think it has really soothed her little gums. Plus, it seems to help build a connection with both dogs. Since I’m holding the bone it’s providing them with something they enjoy and it’s coming from me.
