Great way to keep your crazy puppy busy.
Color: blue
This is our second automatic dog toy we’ve boughten. The first one was big and just had one movement with different speeds. This one is so much better. It’s smaller so it’s not so heavy, perfect for a puppy. It has a soft squeak, at first I was worried it was going to drive me nuts but I don’t even notice it. When it squeaks it moves one way then it starts moving another way without squeaking. Keeps my puppies attention. He likes to grab it and fling it back and forth where sometimes it hits him in the head, thankfully this one is smaller and lighter so it doesn’t hurt him. It’s great quality, seems like the material is going to last through lots of chewing. Would 100% buy again and recommend.

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.
