Get ready for growls and howls. Be prepared for snappishness and snarling. The federal Department of Transportation is proposing new rules for emotional support animals, and those regulations may be coming to an aircraft near you.

Some of you will applaud; some will be appalled. Everyone will have an opinion by the time these rules become the law of the land and air.

At its core, here is what the DOT is proposing:

>> Service dogs, properly trained, are animals that have jobs to do. They are not just pets. They are, however, dogs. No other creatures allowed.

>> Pets that give emotional support but are not trained to do so will not be accorded the same rights and privileges as certified service dogs. This means your emotional support peacock or iguana does not get to sit in your lap or lie at your feet when you are airborne.

You have until April 6 to make your thoughts and feelings known to the DOT.

WHAT IT MEANS

Here is the DOT’s distilled version of the changes it proposes. It will:

“Define a service animal as a dog that is individually trained to do work or perform tasks for the benefit of a person with a disability.

“No longer consider an emotional support animal to be a service animal.”

Example of an allowable service animal: a guide dog for a person who is blind.

Example of an animal soon to be banished to an under-seat crate: a cute little pooch that’s essentially impersonating a service animal by wearing an “emotional support dog” vest.

DOT makes it clear in its manifest that it has wised up to this game: “Passengers wishing to travel with their pets may be falsely claiming that their pets are service animals so they can take their pet in the aircraft cabin or avoid paying pet fees charged by most airlines since airlines cannot charge service animal users a fee….”

By trying to be inclusive, airlines (and the DOT) let the matter get out of hand by failing to define what constitutes a service animal. It explains how:

“DOT’s current (Air Carrier Access Act) regulations also require airlines to recognize emotional support animals as service animals. Consequently, a restaurant in an airport could, without violating (Department of Justice) rules, deny entry to an emotional support animal that an airline, under the ACAA, would have to accept.”

That leniency has led to an increasing number of complaints about service animals (which, under the air carrier act, includes emotional support animals) filed with the airlines, DOT notes: from 719 in 2013 to 3,065 five years later.

The question now is whether the DOT is proposing to do a disservice to those do need their animals and aren’t trying to game the system.

Sandra Barker, professor emeritus of psychiatry at Virginia Commonwealth University in Richmond, would like to see “evidence-based studies” that show how untrained ESAs contribute to the mental health of patients.

It’s not that she does not believe in the value of the animal/human bond. She is one of the authors of “Animal-Assisted Interventions in Health Care Settings: A Best Practices Manual for Establishing New Programs” as part of her work with the Center for Human-Animal Interaction at VCU. The Dogs on Call program at VCU uses trained dogs to address stress among patients and staff.

Is there a place for ESAs on airplanes? Not as we now know them. But, said Catherine Salmon, a professor of psychology at the University of Redlands and a member of the Human-Animals Studies program at the university, the tide could turn with training of those animals. She called the fear of what an untrained animal might do a “valid concern.”

“I think if a system could be set up — if ESAs can have the same kind of training and can be part of the same system that is regulated in some of the same way — that could work,” she said.

But would that change the human-animal equation? Perhaps. Pet owners — and I am among them — are in service to our pets. A service animal is in service to its owner, which makes the relationship more complex, Salmon said.

All of this before we’ve gotten to the topic of allergies and whether it’s fair to expose passengers to that — even if it is a trained service animal.
