Not as soft as it looks
It’s like a hard ball with fur covering. My dogs want to play with it, but have a hard time picking it up. Sounds cool, tho! I wish it was more like a stuffed ball they could easily pick up and throw around

He loves this thing!!! Ignored at first, but now he totes it around everywhere! It's chew resistant ( no stuffing to pick up for me ).

Would buy again
Size: Small Size
Puppy loves this ball. She managed to tear the fuzzy part open fairly quickly but once it was all the way torn the ball inside that makes the noise is as pictured and she can still play with it regardless of the fuzzy part being taken off. Easy to keep track of as it's a tad bigger than a softball. Puppy loves it and it keeps her entertained.

Great turned to not so great
My Doberman (80 pounds in 7 months) puppy absolutely loved this ball. He loves anything noise making so this ball was perfect. Unfortunately, about 2 hours of nonstop play the cover was falling apart. There was no saving in. My pup is rough on toys and this one couldn’t handle it. I let him play without the cover for a little bit but the plastic is VERY hard. I’m not sure what type of plastic it is, but it’s very hard, no your average plastic. It was clunking around and banging into everything possible.
I would love to give it more stars as it might have been perfect for other dogs, or maybe I just got a dud. But having to take the ball away from him was almost heart breaking. Those sad puppy dog ever and him looking everywhere for it. Barking nonstop because, well he want his ball….and being a puppy he is still learning. Had the cover held up for even 24 hours it would have been great. So I have a sad puppy and a lighter pocketbook. It was fun while it lasted.
