Durable and fun
Flavor Name: Beef, Size: Medium/Large
I have two dogs and I only bought one bone over a month ago. They’ve both been chewing on it and it’s held up really well. I wouldn’t say they’re aggressive chewers, but they do like chewing. They’re still picking it up and using it, so they’re definitely not bored with it. As for me, it’s been a pretty great buy.

Tough Chew!
Flavor Name: Original Jerky, Size: Medium
Sporn is a very tough chew. We have a 22pound Beagle 1 year old. She spend little time working on the Hard plastic that encases the marrow. Now I don't doubt there are some dogs that would chew this mindlessly for the small marrow treat. It is not for my pup! She needs more play to keep at it. A TOUGH CHEW would be better slightly less thick and more marrow inside. I attached a string and had her whirly birding around chasing this bone but once we let go she has a 30 second interest. Not for every dog maybe for the big guys 100 lb brutus !

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.
