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.

Pattern Name: Tug Rag
This is the best toy for puppy teeth. If you want to play with your pup you can hold with your hands & it protects your fingers. Our pup does prefer this toy to others & I think it is because the leather is thick.

SOOO DURABLE!!!
Pattern Name: Tug Rag
VERY VERY VERY durable!!!!! I have a Malinois and a Cane Corso who are both very high energy and high intensity. They have shredded every single toy, bite rag, and rope ive purchased butu this one has stood strong for a year so far. i would 100% buy again. could also just be thrown in the washer if it gets dirty which is a HUGE plus for super droolers.
