my dog says NO
Flavor Name: Peanut Butter, Size: 6.9 Ounce (Pack of 1)
My dog sniffs both ends of this bone then walks away. I see in inside of it is very hard so I decided to soak it in some hot water for awhile and see what she does with it. If it works I will update. Update. Soaking didn't help. So that bone went in the trash.

My dogs love them
Flavor Name: Peanut Butter, Size: 4 Ounce (Pack of 1)
My dogs love these. They don’t last very long but my dogs are big, and they aren’t messy. I also like how they don’t stink like some chews.

Long Lasting Doggie Chew
Flavor Name: Peanut Butter, Size: 4 Ounce (Pack of 1)
My dogs love these. They provide a tasty hard treat for them to chew on for hours, and even days. Once too small for safe chewing, you soak them in water then microwave it into a "puff."My dogs know when they are getting them as the aroma is ok. I buy these often and keep them on hand.

Doesn’t last long
Flavor Name: Peanut Butter, Size: 4 Ounce (Pack of 1)
Both my dogs chewed these up way too fast. Disappointing because I was hoping it would last longer. No odor. Size as expected. They seem to like the taste and had no issues in digesting it
