Fun for our puppies

Fun tug of war toy for our heeler pups. They haven't destroyed it yet but time will tell. Cute, and easy to take with us to the park.

Dog toy for heavy chewers
Color: brown1
This is pretty durable. My puppy chews up most stuffed toys. This one is still mostly intact. It’s missing one ear and the tail but the way it was sewn it’s still very usable. It’s one of his favorite toys

Great dog toy! Good quality!
Color: brown1
Great quality dog toy! The rope is thick and not easy to break. Fun toy for my medium-sized dog who loves to tug-of-war with me.

It's cute for the price, but it's meant for small dogs, it's very easy for medium-sized dogs to destroy.
