Kinnelon police Lt. John Schwartz tells The Daily Record of Parsippany the woman let the dog outside on Oct. 6 and soon heard barking. Schwartz says she went out back and saw the pug in the coyote's mouth.
The dog was never seen again.
Police are warning residents to be wary.
Sparta police reported a similar incident in August when a coyote attacked and killed a 20-pound miniature pinscher.
