Recently, another video of a golden retriever went viral, but this animal appeared somewhat less than friendly.

The footage, shared to TikTok on June 23 by Meshally07, begins by showing one dog siiting in the front seat of a silver car looking happy and approachable.

The camera then pans to an older-looking golden retriever perched on the back seat whose eyes are narrowed in a menacing stare in the camera operator’s direction.

Text overlaying the funny video reads: “The chances of being killed by a Golden Retriever are low…. But not zero.”
