Dogs are enjoying it!
Flavor Name: Beef, Size: Medium/Large
I just got this bone today but so far my dogs love it. They have been playing with it and alternating who’s chewing on it. My 8 month old got the blue rubber piece off in about 10 minutes, so if that’s the primary factor for purchasing, note that.

lasted 3 days
Flavor Name: Original Jerky, Size: Medium
I have a 10 m.o. Aussie who is in chronic chew stage. I was hoping that this bone would last longer than Benebone. Watching pup chew her little heart out, I noticed she was tearing off little pieces of the plastic bone and swallowing them. Threw out. Wish I'd returned. NOT RECOMMENDED FOR SUPER CHEWERS

I like it, but
Flavor Name: Wishbone, Size: Large
Two large dogs, two different experiences. They both loved the toy, but one chewed it up within a couple of weeks - much longer than most toys last for him. The other one still loves it and uses it daily,(has had it for two months) but if I don't trim off the sharp points that form, it gets blood from his gums on it. Would still recommend it as each dog is different. Worth a try.

Overall a really great toy for all sizes of dogs
Flavor Name: Original Jerky, Size: X-Large, Flavor Name: Original Jerky, Size: X-Large
I ordered this product on Thursday and it said that it was going to be at my house in a week , but to my suprise it got delivered on that Saturday. My puppy loves these nylon bones. She is a 12lb dog but I ordered the X-Large size, and she loves it! The nylon bones really work in keeping her teeth clean of tar for the most part, and she loves the flavoring inside. The only downfall is when she got to the marrow part it stained my light sheets. I replaced them with darker sheets and there is no trace of the bone. Overall a really great toy for all sizes of dogs!
