HOLBROOK - Animal control officers are looking for a dangerous dog in a Suffolk neighborhood. Valerie DeMasi says she was attacked by a pit bull on Portside Drive in Holbrook on Tuesday evening. She says the dog came out of nowhere, biting her on the shoulder, hip and foot. So far, the owner and the dog have not been found. Since the dog remains unidentified, DeMasi now has to endure weeks of painful Rabies shots.
