KAUFMAN COUNTY (CBSDFW.COM) – Dozens of dogs and puppies were rescued from an alleged puppy mill in Kaufman County Wednesday and the woman arrested in suspicion of organizing it has a history of similar accusations.

A rescue group says the animals had no access to food or water, and are in poor condition.

“The term ‘puppy mill’ does not give witness to the horrors the breeding mothers endure,” said Scotlund Haisley, president of the Animal Rescue Corps. “They are considered machines whose puppies are nothing but products. It is our honor to promise these dogs their suffering has ended.”

They’re now being treated at an emergency shelter at the Kaufman County Fairgrounds.

Margaret Boyd was arrested in suspicion of running the mill and has been accused before. The Animal Rescue Corps helped authorities raid Boyd’s property Wednesday.

The group shot home video of the 50 dogs and puppies, some of them just one day old. Officials said they were living in squalor, in their own urine and waste.

Rescuers say the animals are also malnourished.

“It was bittersweet,” Haisley said. “It was great to rescue these animals. It was horrible to see her puppy-milling again.”

In August of 2009, more than 500 animals were seized from the same property. Boyd was convicted of animal cruelty and Haisley said the rescue came after, “ARC’s Texas State Liaison recently obtained evidence that identified the property owner was in violation of probation.”

A condition of the Boyd’s probation was that she could only keep two dogs and the animals had to be spayed or neutered.

The Animal Rescue Corps also helped conduct the raid two years ago, and has followed the case.

“But I believe, I’m very confident we have the evidence to convict her again,” Haisley said.

There will be a custody hearing for the animals Friday.

As for Boyd, she’s accused of violating her bond and faces additional charges that have not been announced. She denied an interview request from jail.
