A Queensland man has been jailed over secret dog fights that left the animals bleeding, wounded and sometimes dead.
Animal welfare officials seized about 20 dogs from the Mount Cotton property of Jarrad Nathan Trenear in April last year as part of a sting on Queensland's underground dog fighting web.
They found flea-ridden American Staffordshire bull terriers, bull mastiffs, a pit bull terrier, a bulldog and an English mastiff chained in the dirt at the property south of Brisbane.
They had no bedding or clean water and some were covered in scars consistent with dog fighting.
A hundred needles and 50 syringes, amino acid injections, pain relief and anti-inflammatory medicines, antibiotics, electric collars, treadmills and harnesses for pulling weights were found.
Books detailing dog fighting and raising fighting dogs were also uncovered.
Trenear, 35, has pleaded guilty to a string of offences including failing to provide water to the animals, supplying dogs for fights and organising a fight.
He also bred pups for fighting and and kept them in conditions described in Brisbane Magistrates Court as appalling.
At one point during Wednesday's hearing, magistrate Linda Bradford-Morgan held up photos of injured, bloody dogs and asked Trenear if his young daughter had seen the animals in that state.
The dogs were chained in view of each other but unable to touch. That was a method used to build their strength and make them want to fight, RSPCA chief inspector Daniel Young said outside court.
"It's just a really horrible way for a dog to live," he said.
Some of the dogs were so aggressive they were put down after being seized by the RSPCA, while others were rehabilitated and rehomed.
Two dogs were returned to Trenear, who later gave them away to friends.
He has been ordered to repay $6388 in medical fees incurred by the RSCPA and $1500 for its legal costs.
Trenear was fined $800 for failing to provide adequate living conditions for one dog and failing in his duty of care towards another.
He was sentenced to six months jail, but will spend less than a month behind bars before being released on parole on July 31.
