The cruel practice takes place on French-controlled Reunion Island in the Indian Ocean, where Prince William spent two holidays.
A six-month-old labrador pup was recently found ALIVE with a huge double hook through its snout - like the dog above - and another through a leg.
The pup was found in a coastal creek and is thought to have somehow freed itself from a fishing line.
But other dogs and kittens have been chomped up and swallowed by sharks.
The RSPCA plans to petition the French government, demanding an end to the hideous torture.
