Cracked Tooth
Update: While I originally loved this product and so did my dogs, I feel the need to update this review. The Dura Chew Nylabones are incredibly hard, which is what makes them last so long. However, one of our dogs did crack a tooth recently from chewing on a Dura Chew. Since then, we have been very hesitant to allow any of our dogs to chew on these as other reviews also state that dogs have cracked teeth. We have since thrown out all of the Dura Chews that we had. We are still using the regular Nylabone products (when they aren't made in China), but once those are gone we will not buy any additional products from Nylabone. We have been buying Whimzees for our dogs for the last two years or so and they are a healthy edible alternative. They do not last as long because they are edible, but I have the peace of mind in knowing that my dogs are safe with them. Another healthy alternative would be antlers, which we also give to our dogs and they usually last a long time.
Original review: Another great Nylabone product. I love that dogs can chew on Nylabone products and they can't pull off pieces like products from other brands (Hartz for example). The Dura Chews are especially great for our hard chewers and they last forever! I love all of the dimples on their chews too, they're great for keeping our dogs' teeth clean. The vet is always impressed when they check their teeth.

Puppy friendly
Color: Reed, Seaweed & Corn Husk, Seaweed & Corn Silk, Number of Items: 3
This is not designed for dogs who are chewers. I gave this to my adult dog thinking she could play with it and be entertained for a little while. She had it ripped up and spread around the room in about 10 seconds. I would maybe recommend this for puppies to have something softer and gentle on their little teeth and gums. It also makes a bot of a mess once it starts coming apart so I suggest using outside or where it can be contained. Little high of a price point for the value I got out of it

My dog was immediately interested in these. He loves carrying them around and chewing on them. I also like that they’re made from natural materials.

Start with 6 pack assortment to let the dogs choose their favorite. They are fragile and messy.

They are fragile and messy. I only give them to the husky for about 5 minutes as a calming reward. His favorite is seaweed and Timothy hay. Why because we feed Timothy hay on the farm. His second choice was corn leaf. He looked at me like I was crazy when he mouthed the corn silk ball.
In the future I will just get the seaweed hay balls. The sensory taste and smell calms him down.
The old lab is easier on these balls. More licking and sucking than hard chewing.
