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.

My dog loves these things

Size: Large, Color: Femur Bone

My dog loves these things. They don't smell at all. It was a great price. It's big enough for my Frenchie. It's pretty durable but he is able to gnaw it rough so I do have to replace them periodically.

About as indestructible as it gets. It's just very hard molded material. I always make sure to wash the dog toys before letting them play, who knows where they come from. Picture is after hours/days of the built playing with it

Old Faithful

Size: Large, Color: Wishbone, Size: Large, Color: Wishbone

AmStaf/Lab loves this product. I am still concerned about him ingesting the sharp little pieces he gnaws off, but he seems OK after three months of using these. Tried the Nylabone natural/wild products but they are not usable as a "chew" and disappear within minutes, nay seconds! -So here I am back to the "strong chew" wishbone product which makes my dog happy and keeps him busy not eating my shoes. (Be warned though, these are worse than Legos if accidentally stepped on!)
