Query: Not very good

We wanted to get this ball for our Shi Tzu as he loved the one we got from a pet store. Well the same day we got it and gave it to him it quit squeaking. The piece kept falling out if the hole in the back so it doesn't squeak and it had some kind of white powder in it and reeked bad. Don't go cheap but the one at the pet stores.
