The ONLY Bones/Chews Dog-Approved in Our House!
Flavor Name: Original Jerky, Size: X-Large
We have 2 purebred pitbulls, both adult males who weigh between 75-80 pounds. We bought a huge assortment of bones, treats, and chews when we first got our boys (they're rescues, and we got them at the same time). They strongly favored these Marrowchews, even over other, imitation products of different brands.
We actually didn't know they had marrow INSIDE the bones for quite some time, and as soon as we realized that, we understood why our dogs loved them so much! The way the marrow is embedded in the bone, but a ways in from either end, is really clever. The dogs can surely smell it long before they can taste it, and it seems to keep them really interested and motivated at first. Then, they get to the actual marrow, and they are working on these bones non-stop until it's completely gone. The way they are made is also really unique; they sort of 'splinter' as they get chewed, and it actually helps with doggie dental care, cleaning the teeth and massaging the gums. There is no mess with these bones, no pieces flaking or chunking off, anything like that. They are also completely odor-free. With other bones/chews, they'll start them, but lose interest really quickly, and never so much as look at those again. These specific Marrowchews are truly the ONLY ones that keep our dogs interested, and for a significant amount of time, too. They'll work on the XL sizes daily throughout the day for a total of 1-2 hours, and they last a couple of months, easily. And keep in mind, these are pretty
aggressive chewers!
HIGHLY recommend these, and the price on Amazon is the best anywhere!

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
