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.

Good quality, not a bad price
Size: Large, Style: Peanut Butter
Good value. It was cheaper to buy the pack of three instead of buying three separate. I wanted to try different shapes for the dogs. Honestly, they aren’t impressed, but it’s not due to a lack of quality of the product. It’s because they would rather shred Kleenex, eat dog poop, and steal chicken eggs.
