Different animals can make great therapy pets, depending on the individual's preference and needs. Some common therapy animals include dogs, cats, rabbits, horses, and even guinea pigs. Dogs are often a popular choice due to their friendly and social nature, while cats can provide comfort and companionship to those who prefer a more low-key pet. Horses are also used in therapy programs known as equine therapy, which can be beneficial for individuals with various physical or mental health challenges. Ultimately, the best therapy pet is one that suits the individual's personality and needs.
