When the Singaporean opened the door to his Malaysian house last week, he was shocked to find about 30 starving dogs.
The man, who wanted to be known only as Mr Goh, even saw three of the dogs trying to eat another at the house in Taman Pelangi, Johor Baru.
"Some of them escaped when I opened the door and some even tried to eat me," Mr Goh told The New Paper.
It was one of his most frightening experiences.
He took a 13-second video of three dogs attacking a weaker dog when he got there last Wednesday.
"I had to chase some of the aggressive dogs away with a stick.
"I've never seen anything like it."
The house was rented to a Malaysian woman in her 40s, who used to be a veterinarian in Singapore, said Mr Goh.
He had rented it to her since April 2013 for RM3,000 (S$1,100) a month.
But the woman, known only as Dr Lim, stopped paying rent four months ago.
Mr Goh last spoke to her five months ago.
It was only last week that he dropped by to check on the house.
"The neighbour came to me and told me there was a bad smell and he had not seen Dr Lim for two weeks," he said.
"I opened the door and was shocked to find dogs and rubbish everywhere.
"She turned my house into a dog shelter and abandoned them."
