Softness

The pups love it. It’s soft and squishy and crinkly. Pretty colors too.

It’s been several months and all 3 still intact!
I have to be very selective because MOST toys labled recommended for “aggressive chewer” last about 20 minutes. Not kidding. These are the real deal. I’ve had these for several months now and all 3 are shockingly still completely intact and look like they did the day I got them.

Great option
Got this pack of toys for my new Great Dane puppy. He is in a very intense chewing phase and so far these are holding up. He loves that they squeak, and make a crinkly noise in the legs. I love that there is no stuffing to clean up if he manages to get it open. They way the arms move and flail really makes him love these toys. Will buy again when he needs new ones.

Great buy! My dogs love e them
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.
