Dex is a dog with an unruly tail. All the other members of Dex’s family are tough as nails, but Dex is cut from a different cloth. He likes to chat and play, and when he does, his tail wags wildly. When he’s sad, his tail tucks under. Everyone can see exactly how he’s feeling. The rest of Dex’s family find it very embarrassing, so Dex tries to rein his tail in – to no avail.
