I gave this toy very low stars because this has a plastic box inside with springs and batteries that my dog destroyed. Good thing she spits everything out but she could've gotten hurt or cut with the hard plastic inside this toy. I didn't realize this until I saw a bunch of broken plastic pieces and metal springs and multiple "watch like" batteries all over my floor. This could be potentially dangerous if you have an aggressive chewer like my Pitty. Please, if you have a super aggressive chewer that likes to destroy stuffed toys, PLEASE do not get this toy! I buy almost all my dog toys on Amazon and this one I was very disappointed with.
