More than 100 animals have been rescued from an alleged Queensland puppy farm where dogs had apparently been eating the remains of other canines.
At least eight dead dogs were found at the property at Glenarbon, in Queensland's southwest, on Monday.
It's alleged a number of corpses were found near dogs that had been tethered, while one was discovered locked inside a caravan with a distressed dog.
The RSPCA says some dogs required emergency treatment after being rescued from "disturbing conditions" at the property where shelter and water was in short supply.
"There are allegations about dog fighting, however, we found no evidence in relation to that," RSPCA Queensland chief inspector Daniel Young said on Tuesday.
"What we did find was a large number of dogs suffering from various conditions."
Some had severe injuries believed to be caused by other dogs, he said.
No charges have yet been laid over the property and animals, but the RSPCA has been interviewing breeder Haris Ljuhar.
A total of 91 dogs, including between 30 and 40 puppies, some of them very young, and 10 cats were seized.
The breeds included Pitbulls, American Staffordshire Bull Terriers, and French Bulldogs, a very popular breed that typically sells for thousands of dollars on the pet market.
Police alerted the RSPCA after officers went to the property armed with a search warrant for other matters.
The animal welfare organisation is hopeful of rehoming the animals, which are being cared for at its headquarters at Wacol.
Mr Young says the investigation is in its early stages, but expects it to result in multiple charges over a failure to provide duty of care to the animals.
Police and the RSPCA want to hear from anyone who believes they may have purchased an animal from the property.
New puppy farm laws are due to come into force in Queensland in May and will make it mandatory for all dog breeders to register and provide a supply number when selling, giving away or advertising a dog.
