Sadly, there is an online network of individuals and organizations selling service animal certification or registrations implying their customers will have the same protections as a qualified disabled American with a prescribed medical assistance animal.
Regardless of the type of training used, professional or disabled owner, to be deemed complete a Service Dog in Training should undergo independent testing.
To qualify as a protected class, the individual must meet the definition of disabled as declared in the specific law or as stated in the federal regulations published by department deemed responsible for its administration.
Because of multiple qualification possibilities, potentially an individual could meets the legal definition of disabled status under one law, while not being protected under a different law.
In the United States, disabled Americans are granted civil rights protections against discrimination and harassment under the Americans with Disabilities Act (ADA), the Fair Housing Act (ADA), the Air Carrier Access Act (ACAA) and the Rehab Act.
Many states have also enacted legislation applicable for their residents.
