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.

Durable, engaging, and dog approved
Flavor Name: REAL Bacon/REAL Maplewood, Size: Puppy Tiny (2-Pack)
These chew toys are great for keeping dogs entertained and engaged, especially for gentle chewers. The quality feels strong and they hold up well compared to many other toys. The real bacon scent keeps dogs interested and coming back to them often. I’ve ordered multiple packs over time for my own dogs and even gifted them to others because they’re so well liked.

The "Y" is a staple! The other is useless.
Flavor Name: REAL Bacon, Size: Small – 2 Pack
Leaving a 4-star review because she has chewed this "Y-shaped" Benebone almost down to the nubbins. At first she didn't want much to do with it, but something clicked and once she started chewing it, it's become a staple in her chewing repertoire. But the other shape... the double-pull with the lines on it... is apparently not chewable for her. She'll tote it around, but won't really sink her teeth into that one. She's still a puppy, so maybe she'll start on the double-pull shaped one later. But we'll probably hafta get a larger Y-shape in a month or two... that one's totally worth it!

Flavor Name: REAL Bacon/REAL Maplewood, Size: Puppy Tiny (2-Pack)
My dog loves these bones. I love them too because I dont have to worry about him choking in them or biting off small.peices. Great for puppies going through the chewing stage. My dog seeks these bones out over other toys. The size is great perfect for medium sized dog. Material is durable and lasting. Occupy my dog for a long time.
