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!

My dog lives these. Great for the puppy chewing stage.

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.

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...
