They are highly preferred by our pet!
Flavor Name: Chicken, Size: 9.7 Ounce (Pack of 1)
Our dog absolutely dream bone twist sticks! They have a very pleasant scent and are the perfect softness. He gets one in the morning with a few other small treats and always saves this for last we think it’s because it’s the favorite. This is not made of rawhide in therefore highly digestible. Perfect size for a medium to small dog; would not recommend for a larger dogs due to choking. You can, however, get larger bones in the same brand. With 50 in a bag, you can purchase them less often. They are highly preferred by our pet.

Great For Puppy to Elderly Dogs
Flavor Name: Chicken, Size: 9.7 Ounce (Pack of 1)
All 3 of our dogs love this treat, We like that the treats are free of rawhide. They are soft enough for even our 15 year old dog to enjoy. The treats can easily be cut into pieces to use as training treats or to hide in dog puzzle toys. With 50 sticks per bag, we don't run out of them too soon.

Good Treats, But Too Small for Large Dogs
Flavor Name: Chicken, Size: 9.7 Ounce (Pack of 1)
I purchased these DreamBone Twist Sticks for my large dogs. They had no problem eating them, but the treats were much smaller than I expected for bigger breeds. Because of the size, they didn't last very long and weren't as exciting for them as some of the other chews I've purchased.
That said, the dogs did eat them, and the quality seemed good. My dogs can be pretty picky, so their lack of enthusiasm may have had more to do with their preferences than the product itself. I think these would be a great option for small or medium-sized dogs, or as a quick treat rather than a long-lasting chew.
Overall, a decent product, just not the best fit for my large dogs.

Great for older and small dogs
Flavor Name: Chicken, Size: 9.7 Ounce (Pack of 1)
Healthy snack for the pups! I have an Oder dog and small dog both are able to enjoy these treats! They are hard enough to get some chews but soft enough to chew completely before swelling!
