Service animals are specially trained animals that assist individuals with disabilities. The most common type is the service dog, which helps people with mobility issues, visual impairments, or medical conditions like seizures. These animals are trained to perform specific tasks that enhance their owner's independence and safety. In the United States, the Americans with Disabilities Act (ADA) defines service animals as dogs that are individually trained to do work or perform tasks for people with disabilities. Other animals, such as emotional support animals, provide comfort but do not have the same legal status or training requirements as service animals.
