Sporn® Durable MarrowChews™ are the only chewable nylon bones with “Jerky Flavor Down the Middle!” Perfect for strong chewers, nylon shavings act like a toothbrush and help remove tartar from the dog’s teeth. Unlike traditional rawhide bones, this bone will last! The large wishbone shape allows for easy gripping while providing hours of chewing satisfaction.

Gently stop the pulling, and encourage calm behavior.
When your dog pulls,
the harness puts a
gentle, humane pressure
under the front legs.
Your dog slows down,
leash tension is
released, and attention
turns back to you.
You reward your dog
with the calming chew
bone for walking calmly
by your side.
Joseph Sporn invented the original humane dog harness in 1987 to deliver calm control without choke chains or
hard pulling. Every product we make is guided by that same mission.
