It's a miracle. Dogs are changing sex, neutered mutts have regained their manhood, and one amputee has regrown its back legs.
Aucklander Raewyn Tutty's mastiff-cross, Cooper, was the subject of a stunning transformation. "My dog became a boy this year when she was a girl last year."
Karen Laurie's dog went from desexed to "entire". The magic wasn't woven by preachers, or inventors, but in dog registration forms Auckland Council sent to dog owners.
The forms list a dog's name, breed, age, colour, gender and other details.
Tutty, a vet, says she knows of other bizarre cases in the last month. Some people received letters showing dogs had changed colour. Others had changed breeds.
