40lb Lab Retriever Loves It!
Flavor Name: Bacon, Size: Medium
My 40lb Labrador Retriever loves her Nylabone. She DOES chew threw it and it's important to note that it IS plastic, so the product description mentions it should NOT be ingested. The bone eventually does get worn down and she does "bite, then lick" the bone, but she doesn't seem to ingest the entire bone over time and isn't interested in the small, ant-sized pieces of the bone she's carved off with her teeth.
However, over time, the bone does shrink and the edges do get very sharp, so be wary of that. It's not going to hurt anyone, but if you step on it or if it brushes you the wrong way, it could scratch you. Other than that, it's a cheap toy that lasts about a month or so for my dog–a dog that chews up most plush toys pretty quickly.

Indestructible Chew for Aggressive Chewers!
Flavor Name: Bacon, Size: Medium
My pup loves her toys, and the Nylabone Power Chew Stick has lasted two months strong. The durable nylon, flavored with real bacon throughout, keeps her occupied for hours and massaging gums.
The large size suits power chewers, with a loop for tossing games. No splintering or quick wear—it's held up to daily sessions. Peace of mind for pet parents; our shoes thank you!
Pros: Extremely durable, dental benefits, engaging flavor
Cons: None—built like a tank
Would I buy again? Yes, rotating flavors for variety.

If Your Dog Can Rip The Hood Off Your Car--This Is The Dental Toy For Him/Her
I am always curious about buying the "number one best seller" that Amazon lists in any product category. And when it's an add-on item offered at a reasonable cost, I'm even more curious.
From reading the reviews, it appears that some dog owners ordered this item and were disappointed in it for a number of reasons, primarily because the 'hardness' of the toy caused dental problems. Obviously no one wants to buy a dental toy that actually causes teeth problems. However, some small breed owners must not be aware that their particular breed is subject to dental issues regardless of what toys they chew. Just off the top of my head, this type of problem often occurs with Yorkies, Chihauhaus, and Chinese Cresteds. You can use virtually any dental care method in existence and still watch your Chinese Crested's teeth fall out.
So small breeds shouldn't be given tough Nylabone toys like this Dinosaur model. If you watch any dog chew on this particular toy, you will quickly notice how small his/her teeth are in relation to the toy, and you will probably be surprised by the leverage and power he/she puts into each bite. They gnaw, they gnash, they continue to work at it until those tiny teeth lose the battle against the tough Nylabone. Comparing this to human teeth, everyone knows someone who fractures/cracks a tooth somehow. That's because our front "chicklet" teeth bite down on something hard, get broken from falling on your face, getting hit in the mouth, having teeth weakened by cavities, and from not seeing a dentist/hygienist on a regular basis--usually because we're afraid of a little pain.
We're always looking for relatively tough dental toys for our 182 pound Cane Corso named Dante. He tears apart any toy we buy him, usually in a matter of minutes. But this particular Nylabone Dura Chew has survived for months now. If you look at the size of his teeth, length and thickness, you will see a dog with the teeth and jaw muscles strong enough to tear the hood off your car--which is exactly what he did to our Prius. So if your dog is capable of ripping hoods off cars, this treat should be good for your pet monster. Just keep an eye on the toy so that you can toss it before it breaks down and is swallowed.
