Service animals are everywhere. We see them in grocery stores, on airplanes, in restaurants. While a large part of society does not agree with how much freedom service animals are allowed, some people would not be able to leave their homes without them. Some service animals are trained to detect seizures, while others can alert their owners to diabetes attacks. Some service animals guide the blind, while others pull wheelchairs. Some service animals alert the deaf to noises, while others calm people who have PTSD from anxiety attacks. The ADA website is a great resource for those interested in learning more about service animals: https://www.ada.gov/regs2010/service_animal_qa.pd
