The dogs and puppies seized Tuesday from a backyard breeder in the city are clean and on the mend at the Humane Society at Lollypop Farm.

Investigators found the 28 German shepherds — including 13 puppies — living in squalid conditions at a home on Arthur Street. The dogs’ owner, Genie Schultz, 61, was breeding the dogs for sale, investigators said.

She was charged with animal cruelty.

Many of the dogs were kept in crates so small they could not stand up and turn around.

The puppies were covered in their own urine and feces and had developed ulcers on their paws. Many of the dogs were also emaciated, said Andrew Newmark, chief veterinarian at Lollypop Farm.

In time the dogs should recover, but each will need care, training and patience to heal.

“Fortunately, we will be able to work with them to rehabilitate them,” Newmark said. He added that the puppies, with a couple of good baths, medicine for their feet and some soft bedding, should heal quickly.

He said the adult dogs will need socialization training before adoption.

The dogs are not yet eligible for adoption.

Before that can happen, the owner would have to surrender the dogs.

The animals also could be surrendered by court order.
