I have bought 8 of these over the past seven or 8 years. Dogs and puppies love the durable yet chewy feel of them and spend hours teething on these butterfly toys. They prefer them to any other. Only one has gone missing, I daresay lost in the mechanism of a recliner somewhere. My dogs have soft mouths, they could chew them apart if they really wanted to, but they prefer to keep them handy in their dog beds to pass the time. I'm sure I'll buy some again, for crate, car, yard, wherever they spend time I make sure these are always easy for the dogs to reach. They love them.

My dogs love this!

I have been a fan of JW dog toys for a long time and so are my dogs. They take a lot of interest in chewing and are around 12lbs but tiny mouths. I get worried with other products that they will be a health hazard so I wanted something that they can enjoy safely. They love these things and I am no longer have to be worried. They have yet to bite off anything and no sharp edges. I hope it stays this way but so far I'm impressed and already got another one for my new puppy. I definitely will buy more. You can't be the price.

Didn’t last longer enough for “before” photos.

This toy lasted about 6secs period! I literally turned my back to grab my phone and when I turned around it was in about 30 pieces and I know for a fact (💩) that my dog swallowed some. Just a waste of money for me and my Labrador.

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.
