Least Intrusive, Minimally Aversive (LIMA)

In previous posts, I’ve mentioned the Least Intrusive, Minimally Aversive (LIMA) approach to training and behavior.  So, what is it?  The latest training fad?  Hardly.

LIMA is an approach that has been adopted by the Association of Pet Dog Trainers (APDT) and the International Association of Animal Behavior Consultants (IAABC) as a humane and ethical practice of dog training and behavior modification.1  Although this approach was developed for canines, it can be applied to all living creatures.  LIMA incorporates a systematic hierarchy of procedures that should be followed in all cases.

Hierarchy of Procedures for Humane and Effective Practice

  1. Health, nutritional, and physical factors: Ensure that any indicators for possible medical, nutritional, or health factors are addressed by a licensed veterinarian. The consultant should also address potential factors in the physical environment.
  2. Antecedents: Redesign setting events, change motivations, and add or remove discriminative stimuli (cues) for the problem behavior.
  3. Positive Reinforcement: Employ approaches that contingently deliver a consequence to increase the probability that the desired behavior will occur.
  4. Differential Reinforcement of Alternative Behavior: Reinforce an acceptable replacement behavior and remove the maintaining reinforcer for the problem behavior.
  5. Negative Punishment, Negative Reinforcement, or Extinction (these are not listed in any order of preference):
    1. Negative Punishment – Contingently withdraw a positive reinforcer to reduce the probability that the problem behavior will occur.
    2. Negative Reinforcement – Contingently withdraw an aversive antecedent stimulus to increase the probability that the right behavior will occur.
    3. Extinction – Permanently remove the maintaining reinforcer to suppress the behavior or reduce it to baseline levels.
  6. Positive Punishment: Contingently deliver an aversive consequence to reduce the probability that the problem behavior will occur.2

 

As seen above, a humane and ethical trainer/behaviorist will first determine if a behavior is caused by a medical or physiological issue.  Often, they will have their clients consult a veterinarian to determine whether such an issue if contributing to the behavior.  Once this first step is eliminated, they will then attempt to simply remove or modify any conditions or stimuli that are causing the behavior:

Example:  Fluffy stands at the window and barks at passers-by, even though they are a reasonable distance from the house.  Assuming that no medical conditions are involved, a behaviorist may recommend installing shutters or blinds that can cut off her view of the street during times that barking is an issue – like when the baby is taking a nap.

Only when these two first steps have been considered will the behaviorist try behavior modification techniques, emphasizing the positive reinforcement of desired behaviors.  In all cases, a trainer should ask “What do you want the animal to do?”

By emphasizing reinforcement of desired behaviors, and minimizing any aversive measures, a trainer or behaviorist can humanely teach an animal alternative reaction to a stimulus.  Using the above example, the trainer may prompt Fluffy to sit quietly when people walk past the house, or may help Fluffy’s owners desensitize her so that she only reacts when strangers come closer to the house.  However, a trainer who ascribes to the LIMA approach will only use aversive measures, such as a bark collar, only when all other options have been ruled out.  IAABC and ADPT sites for detailed position statements on the use of punishment during training and the use of “training aids” such as shock collars.

Finding a Canine Behaviorist

So, your puppy is growing up, or your rescued dog has been in your home for a while, and your best buddy is turning into a terrible roommate.  Your dog is incessantly barking, or chewing everything in sight, or aggressively charging other dogs, or doing something else that is making you miserable.  You’ve taken the first step and decided that you need help.  Who do you turn to that can transform your problem pet back into the sweet companion that you brought home?

This is the difference between a dog trainer and a canine behaviorist.  A behaviorist is a professional who addresses a problem behavior – namely something the dog does either too often or not often enoughto the extent that it cannot be ignored.  All you need to do is figure out who’s the right behaviorist to help you.  How can you tell whether a behaviorist is reputable?

Like many pet-related professions, this is an unregulated business.  Literally anyone can put up a website, print some business cards, and call himself a behaviorist.  Let’s discuss how you can find one who’s actually put in the time and effort to learn this profession, abides by professional standards and ethics and knows what he’s doing.

First off, a good behaviorist will not:

  1. Start off by saying that he’s dealt with situations like this and knows exactly what to do.
  2. Immediately tell you what’s causing the dog’s behavior and how he’ll fix it.
  3. Guarantee results.
  4. Say that he’ll take the dog to his facility for treatment, and bring it back completely fixed.
  5. Advocate the use of aversive methods or punishments as a standard approach.
  6. Disparage other professionals or their methods.

On the other hand, a good behaviorist will:

  1. Tell you that he will have to determine exactly what triggers and reinforces the problem behavior by careful observation of the dog before, during and after that behavior occurs.
  2. Involve you in identifying the causes of the behavior and implementing a treatment.
  3. Be credentialled by the ABS, IAABC, CCPDT or other reputable body.
  4. Not guarantee results.
  5. Collect data on the effectiveness of the treatment being applied and change the behavior modification program, as needed, based on that data.
  6. Provide you with feedback and progress reports.
  7. Abide by the ethical practices of this profession.

See the difference?  A knowledgeable and ethical behaviorist will implement a program of Applied Behavioral Analysis, which is a structured methodology for changing a problem behavior by modifying the events or conditions that happen before and after the behavior takes place.    He might ask you make video recordings of your dog, keep a record of the behavioral incidents – in other words, take an active role in the treatment.

By maintaining a professional certification, your behaviorist is demonstrating that he is continuing his education and keeping knowledgeable of developments in this field, and abiding by stringent ethical standards.  Most importantly, he will abide by the Least Intrusive, Minimally Aversive (LIMA) protocols for behavior modification.  I’ll get into the details of what this means in my next post, but for our purposes today it means that he will be primarily concerned with your dog’s physical, mental and emotional welfare.

Trainer or Behaviorist?

In an earlier post, I talked at length about the certifications to look for in a dog trainer or behaviorist.  If you took the time to read it, you might be wondering what’s the difference between them.  After all, they do the same thing, right?  Well, not really.  They represent two different disciplines that you might need in living with your dog.

So, you are sharing your home with a pretty intelligent non-human who has social and emotional needs, and communicates non-verbally.  And he is turning into a terrible roommate.  One of you needs help, but what kind of help?  As in all things, that depends.

First, keep in mind that anyone can put up a website, print some business cards and call himself a dog trainer or behaviorist – or dog whisperer, dog guru, dog spiritual healer, dog communicator, or any other title.  This is an unregulated industry, with its share of quacks and frauds.  In the first article in this series, What Do All Those Letters and Certifications Mean? I discussed the various organizations that certify and vet members of these professions.  In the next article, I’ll address what to look for in picking the right person to help you with your dog, but at this point, we’ll discuss what these professionals do.

What is a dog trainer?

Putting it simply, a trainer is someone who teaches you and your pet the skills needed to function well in your home and in society.  This includes manners, pet etiquette and behaviors that are needed to safety and a happy life.  These can range from basic skills such as sitting and lying down on command, coming when called, walking nicely on a leash, traffic safety, etc., to advanced skill levels such as protection training, sports and other activities.

Types of dog training.

The training can take many forms, ranging from multi-dog classes for teaching basic skills to owners and their pets, moderated play sessions for socialization (generally for puppies), advanced group classes, private sessions at owners’ homes, or board-and-train sessions in which the dog lives at the trainers’ location for a time.  In my next article I’ll go into these approaches in depth and discuss how to pick a trainer, but for the time being, it suffices to say that trainers have a number of tools at their disposal, and a number of different business philosophies and approaches.  One size does not fit all.

What is a canine behaviorist?

A behaviorist is someone who can address a problem behavior that your dog has developed.  A “problem behavior” being defined that something that the dog does too often, or not often enough.1   For example, if your dog has anxieties about certain situations – such as being left alone in the house, or your dog barks excessively at the neighbors, or is overly protective of his food bowl, these are problems that the behaviorist can help with reducing.

Behaviorist Methodology

Where a dog trainer uses repetition and encouragement to educate dogs and owners in how to perform certain actions; a behaviorist will work with the owners to observe what the dog does, determine what events or triggers cause it to happen, and develop an intervention to reduce or modify the problem behavior.  The key elements of this are to closely observe what happens before, during and after the behavior occurs; and develop an intervention based on behavioral science and professional ethics.

I hope this helped to clarify when you should seek a trainer or behaviorist.  We’ll get into the mechanics of training and behavior modification in a later article, along with what you should look for when searching for a reputable and effective professional to help you with your dog.
