perfect for tiny breeds!
Color: Blue
this toy is the perfect size for my mini dauchshund mix puppy. I looked in several pet stores for a tug of war rope for something for my little two pound pup that wasn't my socks for him to tug on. so many rope toys are aimed for large breeds, and were larger than my dog himself

Cute size but didn’t last
Color: Blue
I love Kong toys. I bought for my two puppies. One is already broke. But still works like a good tug of war rope with a bonus chew bone.

End of rope your dog or puppy can get the sting in it's mouth
Color: Blue
My puppy loves this toy ,but she can pull the string fiber off the rope so you have to watch that they don't eat the string. Wish the rope was made different with a hard knot at the ends. But my puppy loves the toy .I will just fix the end myself.
