DreamerFi sends along this horrible, horrible one from NatGeo. The
full story is here - basically, this dog was intended to be used as shark bait. From the text of the story:
Live and dead dogs and cats are being used as shark bait by amateur fishers on the French-controlled island of Réunion, according to animal-welfare organizations and local authorities.
...
A veterinarian successfully treated one of the canines, a six-month-old dog with a large fishhook through its snout (see photo), at an SPA (Société Protectrice des Animaux, or Animal Protective Society) clinic in Réunion's capital, St.-Denis.
Unlike most of the hooked animals, the dog was someone's pet, according to Saliha Hadj-Djilani, a reporter for the Thirty Million Friends Foundation's TV program. The dog had apparently escaped its captors and was taken to the SPA by a concerned citizen. Fully recovered, the animal is now home with its owners.
