My dogs love these things but don't last long with my crew. They aren't meant for aggressive chewers. Which mine are but I still buy them because my dogs love playing with them. I have one dog who is a pro at removing squeaky within 5 secs , no lie she's mastered it. Def do not leave your dog unattended. I immediately take the removed squeaky and toss it. My other dog gets the crinkle plastic out whi h I also throw away. They still play with them. I toss them when they are torn to shreds and replace them. My dogs are picky on which toys they like to play with. Which is why I keep buying them.

Not for aggressive chewers

My dogs enjoy them, but the terrier had holes in the head in minutes. Stuffing and squeaker didn’t last, but they enjoy the legs and crinkles.

Nothing is Chew Proof, but these do pretty well

My three 2-year-old Dutch Shepherds have killed every toy except their Kong balls. These octopus toys are hanging in there. My dogs are particularly driven by wiggling the appendages - They LOVE it. My Sheba who normally kills toys immediately has not yet destroyed her octopus. She's been holding it like a teddy bear, that is after she's worn out from throwing it around. I've thrown them in the washing machine and they come out great.
