Not safe, easily chewed bits off
Mixed feelings. My puppies love them and love to chew on them but also chewed the edges off pretty quickly. I had to take away the first one after only a couple days of intermittent chew so it’s really not durable or long lasting. I don’t feel this is safe for a 12 week old puppy which is super small and can be a choking hazard.

Very Small
These are tiny! Just perfect for my little dogs but one was lost within the first few minutes so I had to order another. I'm not so sure how safe it is for the fur children to chew on non-edible, non-digestible plastics but they seem to really like them.

A Hit with Both My Puppy and Older Dog!
I bought the Nylabone Moderate Chew FlexiChew Bone in the peanut butter and bacon flavor for my new puppy, and he absolutely loves them! What’s even better is that my other dog is just as obsessed with them, so it's been a hit with both.
The size is perfect for my tiny puppy, and the flavor keeps them both engaged for a long time. These bones are durable enough to last, even with moderate chewing, and they help satisfy their natural chewing instincts.
If you’re looking for a great chew toy for both puppies and small dogs, I highly recommend these Nylabones. They’re a definite favorite in our household!

My dogs love them
Size: Large, Style: Peanut Butter
One of the few toys my pit bulls can't break. They absolutely love these toys and play chase with them. Usually, they can break toys in less than 5 minutes, but not these.
