In 2017, Marlin Jackson boarded . When he got to his row, another passenger was already in the middle seat with an emotional support dog in his lap.

According to Mr. Jackson's attorney, "The approximately 50-pound dog growled at Mr. Jackson soon after he took his seat…and continued as Mr. Jackson attempted to buckle his seatbelt. The growling increased and the dog lunged for Mr. Jackson's face…who could not escape due to his position against the plane's window." Facial wounds requiring 28 stitches were the result.

Untrained emotional support dogs don't just attack people. highly trained service dogs, as well, sometimes .

I can relate. I am a visually impaired person partnering with my fourth guide dog over a 20-year period. In the past decade, I have increasingly needed to cope with clueless handlers allowing their pets to interfere with my dog's work.

As a , I teach students to consider first the needs of the most vulnerable. I wish I could teach the same lesson to those who risk public safety with their ill-trained dogs, are emotional support animals, a category .

Dogs, dogs, dogs

Over the past decade, have increasingly appeared in stores, restaurants and airports. While , and make the headlines, almost all the animals found in no-pet zones are dogs. Dog , barking, growling, urinating and defecating are top complaints, with one airline reporting an in dog-related incidents from 2016-2018.

The influx of inappropriate dogs has also generated unwarranted suspicion toward the approximately Americans who, like me, partner with legitimate, trained guide dogs.

Animal public access in the U.S. is currently governed by a , creating confusion for people with disabilities, citizens and, particularly, gatekeepers—the store managers, restaurant owners and building supervisors tasked with deciding which dogs should be allowed in their no-pet spaces.

, IDs are issued only to professionally trained service dogs who have demonstrated ability to behave in public. In the U.S., there is no such validation. As a result, pet owners have become in fraudulently claiming their animals warrant legal public access.

Service dogs versus emotional support animals

The Department of Justice, which enforces the Americans with Disabilities Act, allows people with physical, sensory, psychiatric, intellectual or mental impairments to have who have been individually trained to perform tasks that mitigate their owners' disabilities.

The and allow service dogs on public transportation and in housing, respectively, but also grant access to people with mental and emotional disorders accompanied by emotional support animals—untrained animals who need only to contribute to their owners' emotional well being, as any good pet would.

Technically, the individual seeking access with an emotional support animal must have certification of a mental or emotional disorder, which is a much lower standard than the disability requirement of DOJ.

Some mental health professionals have been willing to attest to an individual's "need" for an emotional support animal without having a professional relationship with them. And none vouches for the appropriateness of specific animals.

ADA service dogs may legally accompany their handlers almost anywhere. Emotional support animals may not. For example, emotional support animals currently allowed in aircraft cabins are not legally permitted in airport shops and restaurants. Emotional support animals allowed to live in college dorms may not go with their owners to class or the cafeteria.

of official-looking letters, vests and patches guaranteed to get dogs access in pet-free zones take advantage of the confusion between service dogs and emotional support animals, liberally . They also that the individual seeking such accommodation must have proof of a mental disorder. This omission, itself, is an ethical problem.

A predicament for gatekeepers

Gatekeepers have to weigh the consequences of confronting an individual accompanied by a dog. Denial of access to a disabled handler with a legitimate service dog can result in a by the DOJ. The fine for a handler who falsely portrays a pet as a service dog or emotional support animal ranges from and happens only if the handler supplies identification or waits for the police.

It is cheaper and easier for gatekeepers to just hope that questionable dogs don't put patrons at risk. Airline attendants face a unenviable dilemma, as passengers cannot escape aggressive or stressed dogs in the tight confines of an airplane.

Change on the horizon?

There are recent signs that DOT and HUD are moving toward DOJ's more stringent regulations. On Feb. 5, 2020, DOT opened a for a plan that would reclassify emotional support animals as pets and restrict free aircraft cabin access only to service dogs. HUD recently posted to help housing providers better determine animal access.

In my view, more federal intervention is needed. Medical documentation of disability should be the entry point for service dog access, just as it is for handicapped parking permits. Offering a nationally recognizable ID for service dog owners who voluntarily provide documentation would eliminate some fraud.

Ideally, a dog's ability to behave appropriately in public should be proven prior to access and affirmed annually by testers, who use a public access test to verify a dog's manners and handling of disability-specific tasks, such as that developed by or those performed by all U.S. guide dog schools.

documentation and testing is burdensome or a violation of disabled people's civil rights. But physicians, who diagnose ADA-defined disabilities, already provide their patients verification for state and federal benefits. Behavior tests assure handlers their dogs can work in stressful situations. And ensuring public safety protects the civil rights of all people.
