How do small animals predict the weather?

Animals are the most amiable friends of mankind. They never ask questions or criticize. So is my dog. My little dog wears a white coat and looks as energetic as a soldier. It has a lovely face, eyes shining like jewels, a very sensitive nose, and ears hanging down on both sides like two leaves. Its limbs are flexible and powerful, and its movements are very agile. As soon as it sees its master, it will immediately meet him and wag its tail at him. It looks lovely. If the puppy sees a stranger, it will cock its tail and bark at the same time, until the stranger is scared away, the puppy can feel at ease. My dog is very picky about food. He doesn't even look at the food he doesn't like. He only eats meat and no one can take it away. At night, the puppy shrinks into a "ball" and feels furry and comfortable. In summer, the puppy always slouches on the ground and sticks out his tongue to reduce his fever. In winter, the puppy curled up and looked very cold. I picked up its little blanket and covered it. This is my lovely dog, my favorite little animal.
