Because there are no formal certifications required or even allowed, many businesses have taken up the role to create registries and certifications that are often fake and confuse some handlers, business, and employers – making people think certification or registration are required. Because there is a lot of misinformation about it or if business/employees are not properly informed, this can lead to access issues for handlers and their service animals. Nevertheless, it is not allowed for anyone to claim confusion about or ignorance of legal requirements as a justification for denial of access of service animal teams. Some advocates think formal certification would actually help reduce the number of people abusing privileges reserved for people with disabilities. However, most believe there is not a significant problem that would justify adding unnecessary barriers to access to those that need it. Certification and registration requirements would increase effort and cost associated with owning a service animal for people with disabilities – who often already struggle to afford higher than average costs of living. It would also require increase in governmental bureaucracy and costs associated with enforcement of such requirements. Although legislation and regulations have been around for decades, many business, employers, and organizations are still not properly educated about service dogs. Continued advocacy is important, but also adds an undue burden on handlers, which already have challenges associated with their disability. Sometimes, these challenges make advocacy difficult. Finally, while public knowledge is improving, handlers often have to advocate for privacy, ask others to avoid distracting their animals, refuse interactions, and have to deal with unwarranted attention. Advocacy needs continue to matter.
