Perfect for small dog that likes to chew
Size: Small, Color: Textured Ring
Just got this today (small size for my 15 lb dog) and she loves it. Perfect size for her small mouth and teeth. Keeps her busy and even tires her out and rests a while, Between this type of dog toys and ones that squeak she is having a great time

Durable and Great for Teething!
Size: X-Large, Color: Textured Ring, Size: X-Large, Color: Textured Ring
This Nylabone Power Chew Textured Ring is a great find! It’s a pretty big ring, which is perfect because my puppy can grow into it. She already loves it and spends a good amount of time chewing on it. She’s a big teether, so I was specifically looking for something she could gnaw on that wasn’t plastic, and this has been so much better than the other things she tries to get her teeth into. It seems durable, keeps her occupied, and the price is great for the quality. I’ll definitely be buying another one when needed!

As durable as expected.
Size: Large, Color: Femur Bone, Size: Large, Color: Femur Bone
My dog loves it—more than any other bone she’s ever had. It’s not quite as durable as regular nylabone, but we expected that. This photo was taken after around 2 hours of super aggressive chewing by a very big German shepherd. It has no discernible smell, but obviously it has a flavor because she doesn’t want to put it down even for trips outside. It’s soft enough that it doesn’t cause that “are their teeth breaking?!” sound that a lot of offbrand nylon chews have. The classic femur shape is perfect. It’s the easiest shape for her to hold naturally. All around, perfect dog chew.

Heavy duty chewing, not heavy duty dropping
Size: X-Large, Color: Textured Ring
My super chewer loved this toy, great shape, provided long lasting entertainment. However, when he dropped it from his mouth onto our epoxy flooring (not a far drop as he’s only 50lbs) one chunk broke clean off at the 2 smaller joints. Although we kept the larger piece for a while, a similar drop a week later broke it again. Considering this is fairly inexpensive, I wasn’t expecting it to be indestructible. It’s just strange how it broke. Will probably buy again to test one more time.
