Malaysian and Singaporean volunteer workers found the animals, some of which had been roaming the streets, over the past month amid some of the worst floods in Johor state's history, said Lynda Goh, a spokeswoman for the Noah's Ark Natural Animal Sanctuary in Johor.

``Some dogs had wounds and cuts and they were nursed back to health,'' Goh said, adding that some young dogs suffered pneumonia while two had to have their injured legs amputated.

Johor, Malaysia's southernmost state bordering Singapore, was twice hit by heavy rains that triggered floods since mid-December, leaving at least 17 people dead. Some 100,000 people were forced to evacuate their houses, but more than half of them have since returned.
