A Maine woman accused of abandoning her dog outside an animal shelter has pleaded not guilty to animal cruelty. The dog ran after its owner's car and was later hit and killed by another vehicle.

Twenty-one-year-old Sarah Vye of Auburn entered the plea Wednesday to the misdemeanor charge. She requested a court-appointed attorney.

Police say she left the dog, Abby, in the parking lot of the Greater Androscoggin Humane Society on Jan. 25. The humane society posted surveillance video on Facebook that shows the dog being dropped off.

It says the dog was fatally struck on a ramp to a bridge near the shelter.

Vye has said the dog had nipped her 2-month-old the day she left it outside the shelter.

She is due back in court in August.
