Much sturdier than it seems!
I have a Lab/Pyrenees mix which is a serial toy defluffer. I truly believed these would be in the garbage by the end of a day or 2. Yes the squeakers are in the land of unnamed squeaker graves, but the actual pockets and Velcro lasting like a champ! It takes him a few minutes to unroll them and get the treats out of the pockets. When he gets the late night energy boosts I fill them up and it gets him calm for bed. He will bring them to me if he wants to search for the treats. One of our favorite things. Plus, they are adorable. Total tail wagger!

Puppy loves it!
Style: Turtle
This turtle is adorable!
My puppy absolutely loves it! It keeps her entertained for a while which is a godsend when potty training, and when I’m working from home. The pockets an are big enough to can stuff them full of tons of kibble or treats. She has so much fun playing with & pulling it apart and getting to the good stuff inside and the crinkly noise is a bonus for her as well. It definitely holding up.

Good value, fun play. Poor strings
Style: Monster
This turned out to be one of my Doberman puppy's favorite toys. He loves it and takes it everywhere. I didn't expect much, but the moment it came out of the box he loved it. The colors are still bright after a month of being knawed and chewed on. He loves playing tug a war with it, though the strings are not standing up to well to that. There are three of them, so he has choices. Pluse, he has an extra when missing one.
I think they are wonderfully well made and shaped well to fit for him to chew on. He hasn't torn any stuffing out of it and tears either despite his daily rough play. It is fun watching for seeing him attack those poor little guys.
The strings are only issue. It it slowly coming off in pieces. They are still hanging on, but dying a slow death. Pieces are being found all over the place. I keep a eye to try to make sure he isn't swallowing any.
I, also love the cute designs. The three different ones are so cute I don't have a favorite and neither does my puppy.
He will play with it for a while, not just tug a war. He likes the low low sounding squeaker. Low and now loud and annoying. The materials have a nice smooth feeling and no rough material. I don't mind holding on to it for tug a war or to throw it. It is easy to throw for him. Light but enough weight to send it though the air.
Great value fore the price and the amount of three. I would just take the strings off. They could possibly be a danger hazard.
Overall, I am glad I bought and a good value.

Holds up surprisingly well
Style: Monster
When your dachshund loves these, you buy extra just in case. He’s a tough chewer so I was a bit surprised it lasted very long. It’s going on two months, the legs are almost gone but the squeaker works and the fluff is still inside. He has to have his toy to go to bed so I’ve ordered backups
