A cash reward of $2500 is being offered for information leading to the arrest & conviction of those responsible for putting a dog locked in a carrier in the river.

The Monmouth County SPCA is offering a $1000 reward and the national group is adding another 2500 to the reward. The medium-tan, male boxer-type dachshund did not have a collar or microchip for identification.

Chief Humane Law Enforcement Officer, Victor “Buddy” Amato tells the Star Ledger he believes the dog, with well manicured nails but no collar or microchip, was alive when it was thrown in the river. "To me it’s just horrific," said Amato. "I can’t think of a worse way of going."

The dog was found on Tuesday in the river.
