New Jersey authorities have encountered a second case of dog hoarding this week.
The state's Society for the Prevention of Cruelty to Animals and local police rescued 47 dogs on Saturday from a residence in Hopatcong, authorities told NBC 4 New York.
A 4-day-old puppy and several pregnant dogs were among those rescued.
Many of the dogs were covered in urine and feces, police said.
The dogs have been take to the Roxbury Animal Hospital and will eventually made available for adoption.
On Thursday, authorities seized more than 270 small dogs from a home in Howell in Monmouth County.
Many were sitting on bookshelves. One shelf was specially built near the ceiling of the living room, "like a hamster cage for dogs," according to Tierney Park, a Monmouth Sheriff's deputy. "They have steps that go up to the shelf and there were dogs looking down and barking."
There were others living under beds and even between walls. Many appeared petrified as they were brought out, having never been exposed to the outdoors.
The owners, Charlene and Joseph Handrick, are expected to face charges.
