But that day, everything happened differently. As soon as the girl approached the aquarium, the Labrador suddenly tensed up, lifted its head, and barked sharply. It was as if something snapped inside him: in a single second, he rushed toward the girl, grabbed her overalls with his teeth, and pulled her down to the floor.

The girl didn’t understand what was happening. She screamed, fell down, and started crying louder than ever before. The dog was barking loudly too, standing over her.
