Dog control officers from the Agriculture, Fisheries and Conservation Department launched a hunt in Yuen Long after a toddler was mauled by a pack of strays on Friday.
The 14-month-old child, Chow Shui-lan, was admitted to Tuen Mun Hospital with numerous bites after a pack of eight dogs attacked him outside his home.
He remained in a stable condition yesterday.
A department spokesman said officers caught five strays on Friday night. They returned to the area twice yesterday and caught a further 10 dogs. The dogs were taken to an animal management centre.
The spokesman would not speculate as to whether the dogs would be destroyed.
The attack happened while Shui-lan was playing in a small yard outside his home in Ma Tin Pok village on Tai Shu Ha Road East.
His mother and a man chased the dogs off. The toddler's elder brother said it was not the first time that people had been attacked by dogs.
Villagers said the dogs had originally belonged to the owner of a container parking area, and were abandoned when the business closed down last year.
