2 Samuel 3:8

8 Abner was very angry because of what Ish-Bosheth said. So he answered, “Am I a dog’s head—on Judah’s side? This very day I am loyal to the house of your father Saul and to his family and friends. I haven’t handed you over to David. Yet now you accuse me of an offense involving this woman!

2 Samuel 9:8

8 Mephibosheth bowed down and said, “What is your servant, that you should notice a dead dog like me?”

2 Samuel 16:9

9 Then Abishai son of Zeruiah said to the king, “Why should this dead dog curse my lord the king? Let me go over and cut off his head.”
