A 10-week-old puppy was found dead in a submerged and weighted cage in Passaic County pond on Tuesday and a $5,000 reward has been offered for tips as police investigate.

A rescue officer with The Last Resort, a non-profit, found the dog on Tuesday in Jennings Pond on Bonter Road. The group said the dog appeared to be a young Golden Retriever.

Authorities said late Wednesday the dog was a female retriever.

“The puppy was dead and ice cold, soaked inside the crate, lakebed vegetation hanging on the crate, with a crystal vase (notice price tag),” The Last Resort wrote in a Facebook post. The puppy also had pads stuck to the side of her head with a small amount of blood on them.

West Milford Police Chief Timothy Storbeck and Passaic County Prosecutor Camelia M. Valdes said the incident is under investigation.

“At this time there are no suspects or leads,” Storbeck and Valdes said in a news release.

A veterinarian at Greenwood Lake Animal Hospital examined the dog on Tuesday, then tweeted the puppy would be transferred to New Jersey State Police’s forensic lab for a complete autopsy.

The vet who examined the dog was not available for comment on Wednesday.

The Last Resort is offering a $5,000 reward for information “leading to a conviction of the person responsible.”
