In the doghouse means being in trouble with someone or being out of favor after doing something annoying, careless, or hurtful. It is often used for relationships, especially with a spouse or partner, but it can also describe tension with family, friends, or even a boss.
The expression likely comes from the image of a dog being sent to its doghouse or kept outside as a mild form of punishment. That picture helps explain the modern meaning: someone has done something wrong and is now on the outside socially or emotionally.
People usually use this phrase in a light or informal way. It often suggests temporary trouble, not a serious break in the relationship.
- He forgot their anniversary, so he is in the doghouse.
- I borrowed my sister’s jacket without asking, and now I am in the doghouse.
- After missing the team dinner, she felt like she was in the doghouse with her coworkers.
You can think of it as meaning in trouble, but with a personal, relational tone. It is less about official punishment and more about having upset someone whose good opinion matters.
