Oscar's Law founder Debra Tranter said the group had been negotiating with their breeder - an elderly Jung woman - since the start of the month. 

"The conditions of the dogs are horrific and it is very clear that these dogs have suffered from a range of painful conditions over a very long period of time," she said.

Ms Tranter said the extractions started on July 5, with the surrender of two maltese cross shih tzu dogs.

"The first dog had faecal matts all through his hair, restricting its movement and causing skin irritation," she said.

"Urine burns, caused from living on urine-soaked concrete, to the dog's feet caused the pads to bleed.

"Its teeth were so rotten and had been in its mouth for so long, and when you're swallowing all that disease so often, it becomes systemic.

"The dogs are still having blood tests worked up and may have to be on medicines for the rest of their lives."

Ms Tranter said the dog also had a serious heart murmur, testicular cancer, arthritis and was blind.

She said the other dog was deaf.

Ms Tranter said four more dogs were extracted on July 8.

She said a vet nurse had also attended that day to provide preliminary assistance to the remaining dogs.

Ms Tranter said the four dogs were also in a bad condition.

"All of their teeth had to be removed, and mammary tumours were removed during the desexing operation,’’ she said.

"They all had to be shaved under a general anaesthetic."

Ms Tranter said the work had cost Oscar's Law about $6000. 

She said the group also took dog bedding worth about $200 to ensure the other dogs were warm enough before they could be taken.

On Sunday, Oscar's Law took the remaining 22 dogs to Gippsland to receive veterinary care.

Ms Tranter said the dogs would be rehabilitated and cared for by experienced foster families.

She said the vet work for the dogs would cost about $15,000.

Ms Tranter said Oscar's Law would return to the property next week to extract two working dogs, which had lived on chains, with the assistance of an animal behaviourist.

She blasted Horsham Rural City Council for its efforts with the alleged puppy farm.

“I ask that every domestic animal business in the shire of Horsham is inspected over the next week,’’ she said.

"This is a serious case of neglect and cruelty and I will also be lodging a complaint with the Minister of Agriculture, Peter Walsh."

Horsham Rural City Council relieving ranger Wayne Lane and an RSPCA member inspected the property on Tuesday last week, after Oscar’s Law had first attended.

The pair reported they were reasonably satisfied with the breeder.

Council planning and economic development director Tony Bawden threw his support behind his staff.

"We were really glad our ranger showed the initiative to have the RSPCA present," he said.

Mr Bawden said council would follow up Oscar's Law's claims and would keep a watchful eye on the breeder.

Mr Lane declined to comment.
