    These are quite large for a puppy
    Flavor Name: REAL Bacon/REAL Maplewood, Size: Puppy Tiny (2-Pack)
    These are advertised as puppy but I wish there were still different sizes for the different sizes of puppies. It seems extra small dogs are left out of alot of things. My older larger dog seems to like these but shes only touched it once because these are also quite hard. And my tiny puppy wants to chew these but theyre so big she cant even get ahold of it. I wish there were more options for very small dogs/puppies. Because they seemed to really like these and wanted them but just cant chew them...

    Amazing for Heavy Chewers!
    Flavor Name: REAL Jack Salmon, Size: Puppy (2-Pack)
    If you have a dog that destroys every toy in minutes, Benebone is a total game changer. These chews are incredibly durable and actually last—especially for strong or aggressive chewers. They’re made with real flavors like bacon, chicken, and peanut butter, which dogs absolutely love, and you can tell because they keep coming back to it again and again. What I love most is that they keep my dog busy and satisfied without the mess or smell of traditional bones. They’re also thoughtfully designed with shapes that are easy for dogs to grip and chew comfortably. That said, like any hard chew, it’s important to supervise and replace it if it gets worn down—but overall, this is one of the best long-lasting chew toys out there. Highly recommend for anyone with a serious chewer—worth every penny! 💛🐶💛

    Excellent quality chews. Tiny Puppy size is perfect for adult toy breed dogs.
    Flavor Name: REAL Bacon, Size: Puppy (2-Pack)
    I bought the Tiny Puppy Bacon flavor 2-pack package of these, and my dog and his sister are obsessed with them. They chew on them multiple times every day. They seem to be fairly durable, although I expect they will break down over time, which is okay as it’s a chew. I like that they stay intact, with no chunks breaking off for the dogs to swallow. The dogs do ingest a small amount as the material breaks down, but I always supervise them when they have these, and there haven’t been any problems. It’s difficult to find good chews for toy breed dogs like our 12-pound Shih Tzus, so I was happy to find these. They are pricey, but I believe they are worth it. The dogs love to carry them around, and my little guy even plays with his chew sometimes like it’s a toy.
