A happy dog displays various signs that indicate their contentment and well-being. Some common signs of a happy dog include a wagging tail, relaxed body posture, bright and alert eyes, playful behavior, a healthy appetite, and a willingness to engage with their surroundings and interact with their human companions. Additionally, a happy dog may exhibit behaviors such as smiling (showing their teeth in a relaxed manner), leaning into you for pets, and showing excitement when you come home. It's important to note that each dog has its own unique way of expressing happiness, so it's essential to understand your dog's individual cues.
