An emotional support animal is one that can help you manage symptoms of a mental health issue, such as anxiety or depression. These types of pets offer calming support, nonjudgmental companionship, and a source of joy that can boost your mood and improve your emotional well-being. Caring for an emotional support animal, especially a dog or cat, can also help to ease loneliness, encourage exercise and playfulness, and even add a sense of meaning and purpose to your life.
