Safe and Entertaining Chew Toy
Size: Medium
My dog absolutely loves this toy! She gets hours of chewing time out of it, and I feel so much better knowing the keys are made of a material that’s gentle on her teeth. Unlike harder toys that can chip teeth, this one is durable yet safe, and it keeps her happily entertained. Definitely a great choice for any dog that loves to chew.

Best money spent on a safe puppy chew toy

One of the best chew toys you can buy for your puppy! This kept him occupied for quite a while and it is one of his favorites.

Had a 6mo. old teething (English Bulldog) & this has entertained her for 9 mo.!
Size: Medium, Size: Medium
A chew toy lasting over 6 mo. is generally very good, for this breed & this brand! I kept it in her cage at night, so she wouldn't get board & start chewing on her paws. BC I felt it was a safe toy to use in this manner. "It was safe for my teething Bulldog." "Much, much better than other chew toys from this brand!" Others such as the Orange Pretzel they absolutely love! However, they have always splintered into very sharp edges of plastic, which cause the dogs mouth's to bleed (pokes their gums) & then NEED THROWN AWAY! This Key Chain Chew Toy was "really good" compared to other Nylabone brand chew toys, I have purchased! My girls mouth did not bleed from chewing on it:) "So, I am very pleased with this teething ring!" & would buy it again! Notice how the plastic splinters on the ends? Once the toy gets to his point I feel it is definitely time to be replaced! I would recommend this chew toy for a teething med. sized dog! The one I purchased was fairly large. & stayed together safely:) This is the only Nylabone Chew Toy I would ever, leave in a crate at night, thus far! Good Job Nylabone!

My dogs love their "keys".
Size: X-Small
My dog loves this. The only negative is that he does chew through it and I have to pick up the pieces or hope that he's not eating it.
