A puppy had life-saving surgery yesterday after someone chopped three of its legs and dumped it in a creek in Lantau. One of its legs had to be amputated. Police said a 78-year-old villager found the puppy, aged 10 to 12 weeks, just after 10.30am in Mui Wo Kau Tsuen and it was taken to the Island Veterinary Clinic Service. Workers at the Protection of Animals Lantau South (PALS) said it was the worst case of abuse they had seen. 'The dog had been bleeding for so long it wasn't even bleeding anymore,' said William Tung Man-hung. 'It had been left in a creek near a school. I can't imagine what would have happened if the children had seen it.' The vet who examined the puppy believed it had been lying injured for at least 10 hours before being found and 'her will to live was unbelievably strong'. Another PALS worker, Okka Scherer, said the puppy's chances of recovering the use of her hind legs if she survived were quite high.
