During the wedding, my dog attacked one of the guests and bit her on the arm: we were horrified when we realized why he did it 

It was the happiest day of my life — our wedding day. I was marrying the woman I loved with all my heart. We had been preparing for this day for over a year, and everything had to be perfect. Almost a hundred people had gathered for the ceremony — family, friends, colleagues. It felt like pure joy.

Everyone came up to congratulate us, wishing us love, loyalty, and many happy years together. I was standing among the guests when my bride stepped away for a few minutes to take pictures with her friends.

Suddenly, a woman I didn’t recognize approached me wearing a long green dress. I assumed she was a guest from my wife’s side, and not wanting to be rude, I accepted her congratulations. But there was something odd in her tone. She spoke as if she’d known me for years — recalling details, making hints, joking way too intimately.

I started to feel uneasy. But before I could say anything, something unexpected happened.

My dog, Koko, who had been lying calmly by our table, suddenly jumped up, charged toward the woman, and bit her on the arm. The woman screamed in pain and fear, trying to fight the dog off and begging us to remove him. Guests ran over, including my bride.

— What’s going on?! — she shouted.
— Koko bit one of your relatives! — someone said.
— Who? What relative?

I pointed at the woman in green. My wife stepped closer, looked at her, and whispered in my ear:
— I’ve never seen this woman before. She’s not one of our guests.

Panic broke out. Who was she? Why was she there? Why did Koko react like that? I saw my dog barking and shaking, as if trying to protect us.

We had to interrupt the celebration to figure out what was going on. We called security, and the woman was escorted off the premises. Only a few days later did we learn the terrifying truth about why the dog acted that way and who this woman really was Continued in the first comment 

It turned out the woman was the mother of my ex-girlfriend. We had dated before I met my wife. After our breakup, she went through a very difficult time — lost her job, left the city, and was on the verge of a breakdown.

Her mother blamed me for everything and believed I had “ruined” her daughter’s life. She had come to the wedding to sabotage it. What exactly she had planned, we don’t know. But Koko sensed something was wrong before anyone else.

If it hadn’t been for him… I don’t even want to imagine what could have happened.

Since then, I’ve stopped thinking of my dog as just a pet — he’s my true guardian angel.
