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

DANGER
DO NOT BUY!!! DANGER! We have had the turtle ones before and then got these. Be we bought two. there is a plug peice in the end that popped out. My dog ate it the first time and had to have emergency surgery because it was stuck in his intestines. We had it removed which cost THOUSANDS of dollars. Also was on vacation when it happened and had to come early when the sitter informed us he was ill. We felt guilty for month! had he got something in our house or yard was it our faults. We saved what they removed which looked like a cork but we dont drink wine. we have a frenchie that doesnt enjoys long walks on the beach if you know what i mean so would not have had access to eat something other places he doesnt relaly go anywhere. This was his favorite toy for a long time so when it got dirty outside, we threw away the first one and took out the second one to replace it . One day i was sitting playing fetch with him when i saw the plug peice come out. I caught it and took it out of his mouth. I IMMEDIATELY RECOGNIZED IT. I ran to grab the zip lock bag the vet gave us with the cork looking item covered in gunk and slime from inside his intestines, ran to the sink to rinse it off and what do you know. mystery was solved. This toy could have killed my dog !
