Decent product. Fun for dogs
Size: Dog Rope Toy - M
My dogs loved this toy so much that they ripped it just after a month use. So durability may be lacking a bit but my dogs loved it. The price can be less since it doesn’t last that long, it’s lightweight so it’s easy to throw, and super fun for dogs.

Fun tug toy that holds up well
Size: Dog Rope Toy - M
We got this rope tug toy for our dog and it’s been a hit. He loves playing tug of war and will happily drag this around the house looking for someone to play with. The rope is thick and feels like real cotton, not that super cheap stiff stuff. It has some give to it but still feels sturdy.
So far it has held up well to lots of chewing and tugging. Our dog isn’t a hardcore destroyer, but he definitely tests his toys, and this one is still in one piece. It’s also a nice size, not tiny, so it works well for medium and bigger dogs, but a smaller dog could still enjoy it.
Overall, it’s a simple toy that does what you want it to do. Keeps the dog busy, gives them something safe to chew on, and holds up better than most rope toys we’ve tried.

Red flag!!!
Size: Dog Rope Toy - M
Within an hour of giving this toy to my dog, she chewed off the plastic handle and the plastic ball. The worst part is that they came off in very small pieces, some like crumbles. This could have been a serious problem if I had not been watching her and able to take it away.
