I was betrayed by a dog "expert" that swears by these that they're the greatest thing ever. I suspect Planet Dog has in fact betrayed them by letting their quality control slip. The green parts are glued on, but not very well. I don't leave any toys with my dog unsupervised but my puppy ripped Australia off and swallowed it in only a minute of play. Several of the other continents are peeling off and hanging my a thread. I felt like returning the ball with the green piece, poop and all.
