MOD'S PLEASE REMOVE IF YOU DEEM IT UNNECESSARY!
A Lab mix had to have it's tongue amputated because of a four paws "pimple ball with bell" toy. The toy only has one hole for air in it so when the dog chewed the toy it's tongue got stuck in the hole which created a vacuum, please I urge you if you have one of these pimple ball or pimple dumbbell toys take it away from your dog immediately!
