Really not for aggressive chewers
Flavor Name: Bacon-2Pcs, Size: Medium/Large-under 60LBS
My 4 year old doodle is a very aggressive chewer. I am always looking for chew toys that will last longer than a day these did not!

Great dog bones
Flavor Name: Variety Flavored, Size: Small-under 20LBS
My dogs really like these bones. They are a very durable material and easy for the dogs to hold onto while they chew. They are resistant to the chewing and don’t fall apart. They keep my dogs entertained and happy.

NOT for Aggressive Chewers.
Flavor Name: Bacon Flavored, Size: Medium/Large-under 60LBS, Flavor Name: Bacon Flavored, Size: Medium/Large-under 60LBS
I received 2 of these on May 6th and gave 1 to my Golden retriever then gave my Miniature Heeler the second 2 days ago on May 10th. This image is taken on May 12th. It’s too soft to be labeled for Aggressive chewers because with other bones I have previously purchased the bones have been lasting forever. Which has me concerned about how much plastic-like material they’re consuming. I don’t recommend this one for Aggressive or even Moderate chewers.

JoviQ Dog Chew Toys for Aggressive Chewers
Flavor Name: Bacon-2Pcs, Size: Medium/Large-under 60LBS
These dog chews have been some of my dogs favorites for a few weeks now! They've managed to work a whole end off the t-bone already which is a bit surprising, usually these types of bones take them much longer to make that much 'progress' on so I think these are a bit on the softer side as far as plastic bones go! Otherwise they've worked well for my must-chew-everything dogs and haven't caused any problems (I fully expect them to eat small bits of plastic with these but its that or the walls and carpet so..)
