DOG inspectors were last night scouring the Western area of Hong Kong Island for a Rottweiler dog that attacked a man walking there early on Tuesday morning. A team of six Agriculture and Fisheries Department officials drove around the Catchick and Smithfield street area in Kennedy Town, looking for the dog and its owner, said senior veterinary officer, Dr Liu Kwei-kin. But, without a computer database, the department could not say how many Rottweilers were kept in Western or even in Hong Kong, he said. The department was installing a small computer network which would eventually allow such information to be extracted from the 160,000 licences kept on file. The metre-tall dog, walking on a leash held by a man in his mid-20s, tore a lump of flesh from Kennedy Town resident Richard O'Brien's chin on Tuesday morning when he passed it on the street. The handler pulled the dog away and fled. Yesterday, Mr O'Brien gave officials further details of the attack, after he was discharged from Queen Mary Hospital. He has to return two or three times a day for rabies and tetanus injections and for changes of dressing on the wound, which has not been stitched. Dr Liu said the department would find the dog: 'It's only a matter of time; the man must take the dog out.' The animal could be put down if it was thought likely to attack again, said Dr Liu. The Rottweiler owner could be liable for a $10,000 fine under the Rabies Ordinance for not reporting the bite. Information was being fed into a newly-installed computer network of four terminals, one in each of the government kennels, which would allow information such as addresses of all dogs of one breed in one area to be extracted, said Dr Liu. 'I admit we are handicapped now,' he said. 'The information is on each individual piece of paper, and we are talking about a whole warehouse full of licences.'
