The Monmouth County SPCA says it acted on anonymous tips that there was a second animal at the home of Keith Morgan, 55, and Shauna Morgan, 44.
Victor "Buddy" Amato, the chief humane law enforcement officer with the SPCA, told NBC 4 New York that he sent two officers to the Morgans' home, and the couple agreed to sign the dog over voluntarily.
Amato said the 3-year-old female, Ady, was in "one thousand percent better condition" than Samurai, an approximately 13-year-old cocker spaniel being nursed back to health at an animal hospital in Tinton Falls.
The Morgans brought Samuari, or "Sammy," an ill, emaciated cocker spaniel to Associated Humane Societies, saying they found it in a bag on the side of a roadway in Wall Township. They were charged after "interviews with the suspects and facts presented," according to Amato.
It was not known if they had a lawyer.
Amato said that the SPCA now owns Ady and that he will attempt to bar the Morgans from any future animal ownership as the case of Sammy moves through court.
"I don't want them so much as owning a gerbil," said Amato.
