THE dog which killed its owner's eight-year-old niece in Sheung Shui last week will be destroyed within the next few days. Liu Kam-tong, a villager of remote Wah Shan Tsuen, yesterday signed an agreement to surrender the killer dog - a Great Dane - and his Dalmatian to the Agriculture and Fisheries Department for destruction. The dogs are being kept in Shek Wu Hui government kennels to see whether they have rabies. A department spokeswoman said: ''Observation normally takes seven full days from the day of the biting. If there is no case of rabies, the dogs will be put down as soon as this Sunday. ''Vets said the dogs had so far shown no signs of rabies.'' A girl trying to save victim Liu Wing-yan was slightly injured. The Director of Agriculture and Fisheries, Dr Lawrence Lee Hay-yue, said officials had made the decision because the dogs were a threat to the public. There has been mounting pressure among the villagers since the attack to have the dogs destroyed. Dr Lee said the Government was considering draft recommendations submitted several months ago that legislation be introduced to ban the import of dangerous species of dogs, such as fighting dogs. But he said the Great Dane would be unlikely to be on the list as such dogs were normally not regarded as dangerous. The tragedy happened on Saturday. Wing-yan was playing with friends outside her uncle's house when she was attacked by two of his dogs. The Great Dane mauled her head and neck for about 20 minutes. A post-mortem examination showed she died of loss of blood. Police said they might seek advice from the Legal Department on what action they could take. A police spokesman said it would be too early to decide whether the owner would be prosecuted and it was likely an inquest would be held.
