Police say 37-year-old Nathan Burke of Hancock was arrested shortly after the Feb. 16 incident on Wileys Way.
He reportedly pushed his live-in girlfriend and broke her cellphone so she couldn't call for help.
“The officers got both the stories from both sides and they felt they had enough to arrest him for domestic assault and violation of bail,” said Capt. Troy Bires of Ellsworth Police Department.
For reportedly breaking the cellphone, Burke was charged with obstructing the report of a crime.
Burke and Justin Chipman, 22, are charged in the death of Franky, a 30-pound dog, who was taken from his home in late August, shot and dumped in the ocean.
Both men face five charges, including felony aggravated cruelty to animals.
Burke entered a not guilty plea in the domestic violence assault on Tuesday and the judge set a $750 bail. However, Bires said, he's still at the Hancock County Jail for violating his bail conditions in the animal cruelty case.
