Police are offering a $5,000 reward for information leading to the arrest of the person responsible for abandoning a pregnant pitbull in Waterbury.

The dog, now named Cassie, was found alone in the rain and tied to a sign Sunday near Cherry Street.

Cassie was in labor at the time. None of the puppies survived.

Desmond’s Army Animal Law Advocates are seeking to identify the individual.

Anyone with additional information is urged to call (203) 564-6941
