I highly recommend these for aggressive chewers. These saved everything from the flowerpots to our shoes from falling victim to her need to chew. She now takes her bone with her inside & out & when she feels the urge, she gnaws on it for long periods of time. It also helps keep her teeth & gums healthy.

Pros: Keeps dog busy, long-lasting

Cons: none

This bone saved many a shoe, kid's toy and furnature in my house when our dog was a puppy.
By far the best and more durable teether bone available. The nubbiness must feel good on their gums because our pup just loved mouthing this, especially after it was in the freezer for an hour.

Pros: Durable puppy teether

Cons: none

This is a pretty decent bone when there are few other alternatives for your dog to turn to. I used these periodically to keep my dog occupied in her kennel on occasion. If there is anything else more appealing or delicious laying around then chances are the Nylabone will be ignored.

Pros: Neutral, so great for sensitive stomachs. Helped a bit with dental cleaning

Cons: Not the most appealing or tasty of bones/treats

My dog usually is done with traditional chew toys in about half an hour, raw hide "bones" and composite chews.

The Nylabone doesn't give in to his chewing. he stays interested in it because of this, I think. He LOVES to destroy things and this one gives him a battle!

Pros: He doesn't destroy it, its safe

Cons: None

These are great bones that keep dogs busy for hours and even days. They last a really long time.

Pros: keeps them busy

Cons: none
