Too expensive
This dog toy did not hold up due to poor manufacturing in my opinion.

Good for a while
Pattern Name: Tug Rag
My GSD puppy, at 6 months made shredded leather out of this in a matter of weeks. Initially it was fine but if you spend more than an hour or two playing with your dog, chances are this toy will begin to tear.

Crazy how much our dog loved this
Pattern Name: Tug Rag
It is crazy how much our baby loved this thing. Has held up decently except she chewed off the handle like a goober. Fun to play tug of war with. Soft and safe for teeth. She loves carrying it from room to room, nice and light.
