A guide dog, also known as a seeing eye dog, is an assistance animal trained to lead blind or visually impaired individuals around obstacles and through busy environments. However, there are several other terms used to refer to these loyal companions. They can be called service dogs, assistance dogs, or mobility assistance dogs. Additionally, they can also be classified based on the type of task they are trained to do such as hearing dogs or seizure response dogs. Regardless of the term used, guide dogs provide an invaluable service to those who rely on them as their eyes and ears, enhancing their independence and quality of life.
