Octopus dog toy
My dogs love this toy! They love to play tug of war with it, using the rope legs. The legs will pull out if they are strong dogs! But if the dogs are having fun with it, it isn't a problem. One of my dogs has shredded some of the legs and put a hole in yhe body, but she is a strong chewer. There is a squeaker in the octopus body. They enjoy the toy, so I would recommend it.

Decent toy! Dog ripped off legs after a couple days.
As the title says the toy was pretty durable and it’s made of a good rubber which makes it durable. My dog is a medium sized pomsky and she had a hard time gripping the shell part. I stuffed the middle part with treats which by the way DO NOT do that. My dog got really frustrated bc the treats weren’t coming out and idk what happened bc she ended up gagging and coughing. No throw up tho so good enough for me. While my review seems pretty daunting it’s really not a bad toy if you make sure to keep an eye on the rope appendages.

New pup loves it
Our pup is a chewer but she doesn’t like normally toys or bones unless someone else is also playing with them with her. I searched for interactive toys and loved the little turtle so I decided to try it for her! We both work from home and play with her 80% of the day but that other 20% she needed a toy! My pup LOVES this toy (also loves the box that came with it haha). She plays with it by herself for a super long time and it keeps her entertained. She loves chewing it and also loves trying to get the treats. If you have a dog that’s picky about toys, this is a good one!

Husky chew proof....so far
My husky has a habit of gutting and destroying any squeaky chew toy I have gotten for her. This one so far has lasted a over a month now I must say it does make her work for a treat when hidden in the center of it. So far all the stitching and parts are attached and like new. The plastic center where you hid the treats is intact, the firmness of it does make it difficult to get the treats you put in hard to remove-so choose wisely and not put in large pieces as there is one of the first pieces still inside the center as even I can't get it out. So my girl she enjoys carrying it around and playing with it so this chew toy is a win for this husky owner
