Some dogs are very smart, especially those selected as military dogs, whose intelligence could be estimated to be about the same as a child's. It's not strange that they can understand human speech.
Wang Tao immediately squatted down in front of Lightning with a big smile on his face.
"Lightning, from now on, you'll follow me. If I have a bite to eat, you'll have one too. How about it? Bark once if you agree."
"Woof!"
"Haha, great!"
Wang Tao immediately rubbed Lightning's head vigorously and then took out a bottle of nutrient solution.
"I don't have much food on me, so this will have to do for now."
Wang Tao poured half a bottle for Lightning, and it licked it up with a few strokes of its tongue. Then its gaze at Wang Tao even seemed to sparkle.
Wang Tao liked it more the more he looked at it. He checked Lightning's body; it was a one-year-old female dog, and apart from being a little skinny, it had no other issues.
