A tear broke my heart ―― it was a dog's tear. That night, as usual, I held my puppy. I really hope that time will stand still forever at this moment, so that I can recall and smell it from a distance. At the moment when the dog looked up, I was shocked: its bright pupils were full of tears. My heart is sour, and memories related to dogs also come to mind at this moment. When I brought the puppy back, the leaves on the tree were flourishing. That afternoon, the puppy kept jumping around in the bathtub, but it still didn't climb out of its dirty little face. Yellow and white fluff covers watery eyes. The whole family was attracted by this little guy, and I was even more excited. Since then, whenever we come back from school, the dog always runs around us and wags its tail at us. Once, the puppy kept running back and forth in the yard. My brother picked up a stone and threw it at the puppy, just hitting it. The puppy immediately turned against his face and rushed to his little brother like a madman, scaring him into crying. The bark actually frightened the puppy. He stepped back, just stood there, just staring at his little brother, not knowing what to do. That funny expression made us all laugh, and his little brother burst into tears. More and more big dogs look after their homes carefully every day and play happily with us. Now, this dog is obviously jumping in my field of vision, but I don't feel any joy. The dog lay gently in my arms, let me touch its soft fur and touch its face. Every time I draw a beautiful arc on it, my heart hurts once. Time is a cruel guy, and the puppy gradually becomes an old dog. It doesn't jump around as soon as it sees us, it becomes lazy, it becomes old, ugly and irreversible, and its hair doesn't shine anymore. It squats in the corner every day and enjoys that little sunshine. One day, I overheard my grandmother say to my grandfather, "It's not that I'm cruel, but that dogs really have nothing to raise." Make something delicious today, sell it tomorrow, and maybe make some money. "My heart sank in an instant, but I looked at my grandmother's non-negotiable. I didn't say anything, my heart was torn by grandma's words. It will leave me tomorrow. How can I live without it? I really don't know, if it is as lovely as before, grandma may not have the heart to sell it. The dog seemed to notice something, silently lowered his head and sniffed my cold hand. I hugged it, as if it had been taken away with a rope and put into a cage, and it was about to become someone else's food. It is hungry, looking at countless scars on its body and crying in the cage. No matter how far away it is from me, that cry will break through the night and sting my heart. Inevitably, I saw its sad and desperate eyes again, and I hugged the dog tightly. I hung my head, and its sparkling eyes were particularly dazzling in the dark, shining with sad and dim light. I untied the rope carefully, combed its neat hair over and over again, and said in a trembling voice, "Run, be good, and never come back." "The dog silently lowered its head and enjoyed my touch until it looked up and I saw the helpless face. I couldn't bear to watch it any longer, so I gave it a sudden push and the puppy left step by step. Suddenly, we stopped in the yard where we often played, turned around, and an amber crystal overflowed from the corner of our eyes and rolled to the ground. I fell hard, as if my heart had fallen to the ground. This pain came like an avalanche and drowned me! I stared at it silently for a long time. Suddenly, the dog suddenly turned his head, and the shadow trembled and disappeared into the darkness ... The next day the dog shed was empty. However, no one mentioned the dog again ...
