Danielle Gletow, the founder of Trenton Animals Rock, the animal rescue caring for the dogs, told Fox News that 52 dogs were rescued.

“I was there to let in the dogs when they were being brought in to the shelter from the house and as you can imagine, it’s shocking and upsetting to see so many dogs come into the shelter in such poor condition,” Gletow said.

“The outside really surprises the dogs. They have no concept of being outside,” Gletow said.

She said four of the dogs are in an animal hospital. One is in critical condition, another is in surgery and the other two are expected to be released to a shelter in a couple of days, Gletow said. She added that 16 dogs are at The Trenton Animal Shelter and the rest were taken to different local rescues where they will be fostered.

“I hope every single one of them finds a loving, happy home,” Gletow said. She said the dogs are not currently available for adoption.
