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

For small dog

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

Small Pug Enjoyment For All!
Color: brown1, Color: brown1
We got this toy to replace an earlier purchase for a rope/squeak toy after finding he loved a holiday purchase by an Aunt which squeaked but was not really meant for tugging/heavy playing like he wanted too, for our half pug/schnauzer Mr. Pug. Compared to the first toy and the attempted replacement he ADORES this toy! As you can see in the above picture he has truly laid his claim to it! About the product in general though, we found it surprisingly sturdy all around, even with heavy tugging and aggressive play. The interior padding is durable it seems, and holes where the rope come out have a heavy duty padding for the target dog audience like ours in preventing him from chewing or tearing it up. The crinkly ears were also an enjoyable surprise for him, and the squeaker can move around the torso area of the toy keeping him actively looking for it when he desires it. All in all we would certainly get another toy like this in the future.
