Almost a hundred animals, cramped into cages not much bigger than themselves, were rescued from a bungalow in Subang, Selangor.
They were in an unkempt yard that reeked of a strong stench and was littered with various automobile parts.
On Sunday, members of animal rights group Malaysia Independent Animal Rescue (Miar) and the police swept into the compound, which is believed to be an illegal animal breeding facility.
The case has been described as the "biggest and worst case of animal abuse" in the country.
Around 80 dogs were found on the premises - some in cages and others restrained - along with three cats, two geese, several birds and chickens and a gibbon.
Journalists covering the early morning raid reported an overpowering smell of faeces.
Among the dogs rescued were breeds such as shih tzus, poodles, pomeranians, bull dogs, pit bulls and bull terriers.
"This is the biggest and worst case I have dealt with because there are so many animals involved," said Ms Puspa Rani, president of Miar.
"I have seen illegal breeders with around 20 dogs or so. But I've never heard of one on this scale," she said, adding that she was "shocked" and "devastated" to see so many animals in poor condition.
"Some have open wounds while others can't walk. Some are blind. Many are also severely malnourished, with several not having food or clean water. They need urgent treatment," she said.
Ms Puspa had lodged a report at the Kampung Baru Subang police station following a tip-off on Facebook about the compound.
"I will be lodging another report with the Veterinary Service Department and Perhilitan (Department of Wildlife and National Parks in Peninsular Malaysia) so that they can carry out an investigation into the matter," she said.
Pedigree puppies bred at such facilities can sell for RM1,000 (S$375) each, she added.
Ms Puspa believes that the bungalow owner - a 52-year-old mechanic and his wife - also had in their possession some protected species that might require documentation from wildlife authorities.
"The monkey is a protected species and I suspect some birds are as well."
Both the owner and his wife have been cooperative so far, surrendering the animals into the group's care.
Animal abusers can be fined up to RM50,000, or jailed for not more than a year, or both, under the Animals Act.
The Star had previously highlighted that a rising demand for cute pedigree puppies has created unethical and cruel "puppy mills".
