A service dog is any dog that has been individually trained to perform tasks or work for a person to help mitigate a debilitating disability. Service dogs do not need certification and are allowed public access. They help people with physical and psychological disabilities by performing tasks like retrieving items, providing stability, and calming anxiety. While service dogs have public access rights, emotional support animals and therapy dogs do not. Some stigma still exists around service dogs due to ignorance, invisible disabilities, and personal questions about a person's disability. Education is key to initiating change and reducing discrimination.
