Why is this the answer?

The answer is dog because this riddle is a very clever word puzzle! It uses words that make you think about people putting on clothes, but it is actually describing the amazing ways a dog's body keeps itself comfortable during different seasons. It is a fun trick that teaches us about how our furry friends deal with cold and heat. Let's start with the first clue: "wears a coat in the winter." When the weather turns cold, especially for dogs that spend time outside, their bodies are very smart. They grow a thicker, fluffier layer of fur. This dense layer is their natural winter coat. It works just like your heaviest jacket, helping to trap their body heat close to them so they stay warm and snug when the temperature drops. This is a very important adaptation that allows dogs to enjoy playing and running even when it is snowy or frosty outside. The second part, "and pants in the summer," is the sneaky, clever part of the riddle. This is where the riddle uses a word that sounds like clothing but means something else! Dogs don't wear summer trousers, but when they get hot, they need a special way to cool down. Since dogs can't sweat all over their bodies like humans, they use a process called "panting." Panting means they breathe rapidly and shallowly with their mouths open and tongues hanging out. This quick breathing helps evaporate water from their tongues and lungs, which cools their blood down. The riddle is playing a fun trick by using the word "pants" to mean the action of panting. So, the riddle is a perfect match for the dog! The dog has its thick, furry coat for the winter, and it "pants" to cool off in the summer. It's an excellent example of how riddles can teach us about language and the natural world all at the same time.
