A Port Chester man was arrested Thursday after police say he tried to hang his girlfriend's dog before hitting her.

Christopher Hyatt, 20, allegedly grabbed the 8-month-old pit bull -- which was a Valentine's Day present -- after it relieved itself in his village home shortly after midnight, police Lt. James Ladeairous said.

He then tried to hang the dog on a ceiling pipe by its leash before grabbing a shotgun and threatening to shoot the pooch, Ladeairous said. Hyatt eventually released the dog, but later hit the 18-year-old woman in the face, giving her a bloody lip, Ladeairous added.

Hyatt was charged with attempted assault in the third degree, along with an animal cruelty charge, Ladeairous said. He was arraigned Thursday in Port Chester village court and released on $250 bail.

The girlfriend and her dog were driven back by police to her Hastings-on-Hudson residence.
