I bought a new couch, but my dog started scratching and biting the armrest. I finally lost patience, cut open the fabric, and found something horrifying inside the sofa 

I spent a long time choosing a new couch — I wanted something comfortable, stylish, and perfect for my living room interior.
Eventually, I found the ideal one in a small furniture shop that, as I later discovered, specialized in restoring and reselling used furniture. From the outside, the couch looked completely brand new.
The moment I brought it home and placed it in the corner of the room, my dog Jerry walked over and immediately became alert. He’s usually calm, but this time he started acting strangely. He slowly circled the couch, sniffed the legs, then the armrests, and then kept focusing on the right armrest. Suddenly, he began scratching at it with his paws.
“Found yourself a new favorite spot?” I laughed.
But Jerry wouldn’t back off. He barked, scratched the couch, and sniffed harder and harder, as if he knew there was something hidden inside. I tried distracting him with toys and treats, but nothing worked. All of his attention stayed fixed on that one armrest.
A couple of hours passed, and I started getting nervous. Jerry normally never acts hysterical. If he was this persistent, something had to be wrong. Unpleasant thoughts started creeping into my head. Maybe there really was something wrong with the couch?
I grabbed a knife and, after hesitating for a moment, cut into the fabric of the armrest. Inside was yellow stuffing, springs, old wood, and… something black.
I carefully ripped it open further and realized with horror that it was a dead snake. Long, coiled up, and already beginning to decompose. The smell, which had been trapped inside the fabric, instantly hit me. I jumped back while Jerry growled, almost as if he was warning me to stay away.
After throwing away the armrest along with the snake, I called a sanitation service. They confirmed that the snake had most likely crawled inside the couch while it was stored in a warehouse or sitting in a dump, and later died there.
Apparently, the couch had simply been reupholstered without anyone bothering to check what was inside.
Since then, I never buy secondhand furniture anymore.
And Jerry now sleeps only on the floor, as if he no longer trusts a single couch in the world. Honestly, I understand him.
