Rexa, the little girl with guard dog's mind, was crawling on all fours in her backyard, her eyes sharp and fierce. She barked loudly at the imaginary intruders, growling like a guard dog. "Stay away from my house!" she shouted, her voice strong and brave. With her hands and knees on the ground, she looked ready to protect her home at all costs, showing everyone that Rexa was a tiny but mighty guardian.
