    Good toy but not indestructible
    Color: Royal Blue
    The toy is nice, but my dog killed it in about 30 minutes. The only reason I didn’t give it five stars is because it says indestructible Toy in the description. Other than that it is a nice chew toy.

    Dog loves it. So 5 starts
    Color: Carrot Orange
    A great value toy that is very hard to destroy. Our dog usually runs through softer toys and this one has lasted a long time. Its not chewable like a plushy but harder fabric that doesn't rip apart. The dogs are having a blast with it. And so are we. The colors fit the description. The size was idk 2ft ish. It met all expectations. I wouldn't expect to need more than one of them unless your dog is a super destroyer.

    poor quality product
    Color: Carrot Orange
    very poor quality. The actual color is not as picture. more like being washed many times. the rope knots went loos almost immediately after a few play. The worst part is the so called "squeaky" whistle, you have to squees very hard to hear a little sound. don't buy it!

    Very well made and sturdy
    Color: Carrot Orange
    This toy isn’t quite indestructible but it is very sturdy and so far I’m pleased. I have a 5 month old who is a chewer and she has destroyed toys at a fast pace. It’s just the right size and weight for her to toss around, and I have thrown it in the washer inside a mesh bag once already. The fabric is soft, yet very strong. The only casualty to it was an ear. One had to be cut off once she had it partially chewed off. That’s a win in my book!
