The  question  of  how  one  defines  determines  and  maintains  best  practice  is  one  that troubles individuals, organisations and professions alike.   In the fledgling, unregulated industry of animal training, the Pet Professional Guild (PPG) has worked in conjunction with James O’Heare (President of the Companion Animal Sciences Institute and Director of the Association of Animal Behaviour Professionals) to deliver to its members a guided delivery system for best practice.

Definitions of best practice vary with information sought.  Some definitions are purely result driven

“Methods and techniques that have consistently shown results superior to those achieved with other means and which are used as benchmarks to strive for”1

whilst others take a wider view of the subject.

A process, method, technique or activity that conventional wisdom considers to be “…more effective at delivering a particular outcome than any other technique, method, process etc. when applied to a particular condition or circumstance.   The idea is that with proper processes, checks, and testing, a desired outcome can be delivered with fewer problems and unforeseen complications...A given best practice is only applicable to particular condition or circumstance and may have to be modified or adapted for similar circumstances.   In addition, a “best” practice can evolve to become better as improvements are discovered.”2

The “particular condition or circumstance” to which animal trainers desire to establish best practice  is  training  animals  thus  modifying  their  behavior.    Friedman3   suggests  that  a standard needs to be set to determine procedures for behavioural change.   She states “Without such a standard, we are likely to intervene on the basis of effectiveness alone, without due consideration of humaneness.   To be maximally humane, our interventions should be as un-intrusive for the learner as possible and still be effective.”3

Carter & Wheeler4  cite Alberto and Troutman’s  four level intervention hierarchy where

Level l interventions such as differential positive reinforcement schedules are considered “…to be the most socially acceptable while maintaining the highest amount of counter control for the participant (i.e., least intrusive)”4.  This hierarchy proceeds to Level II which includes “…extinction procedures which involve terminating reinforcement that was previously available to the student.”4    Level III interventions include time out procedures (“…denying a student the opportunity to receive reinforcement for a fixed period of time”4) and response-cost procedures (“…removing specific amounts of reinforcement contingent on problem behaviour”4).  Level IV, the most intrusive of the levels, includes unconditioned aversive stimuli, presentation of stimuli which causes pain, conditioned aversive stimuli and overcorrection procedures.

Friedman3 agrees with Carter and Wheeler4 that social acceptability is an important component of compliance with an intervention and also that “…the degree to which the learner maintains control while the intervention is in effect”3 is of importance.  She believes that considering the continuum of learner control is “…essential to developing a standard of humane, effective practice”3.  She goes on to say that “Research demonstrates that to the greatest extent possible all animals should be empowered to use their behavior to control significant events in their lives, i.e. to use their behavior effectively to accomplish a desired outcome.”3     (Empowerment Training - Conditioning for General Behavioral Well-Being in Companion Animals by James O’Heare (2011) is a modern effective guide to empowerment training.)

Intervention hierarchies that are both ethical and feasible to implement would be “…in the best interests of captive animals, their caregivers and the professionals working with them to solve behavior problems”  (Friedman3).   Further, Friedman says that by choosing the “…least intrusive, effective procedures (i.e. positive reinforcement-based and empowering) we increase the humaneness of our interventions without compromising our learning objectives.”3    To this end Friedman also developed a hierarchy of behaviour change procedures using the most positive, least intrusive effective criteria.3

O’Heare5   has  also  refined  a  behaviour  intervention  model  that  the  PPG  will  use  to determine the least intrusive methods by which an animal should be trained.   O’Heare5 states “Questions such as whether to use aversive stimulation, under what conditions and how to choose what form it will take in a behavior change program are always about weighing the likely benefits and the likely risks of the intervention in question, in the context in question.”  He, like Friedman, agrees that “…effectiveness is not sufficient to justify highly intrusive interventions.”5

In order to fulfil his statement that “…it is important to remember that, because we are committed to “do no harm”, we are ethically obliged to ensure we choose the options that are the least intrusive possible”,5 OHeare offers the following table.



Level 1:

Antecedent control procedures

Strategy and explanation: Antecedent control procedures. Manipulate function altering stimulation to promote choice of desirable behaviors over problem behaviors including emotional arousal. Address variables such as medical conditions, nutrition, mental/physical stimulation, stress-inducing environments, etc., such that problem behaviors are less likely to occur. Counter-condition problem emotional responses with systematic desensitization in order to make consequences for motivated operants moot.Manipulate discriminative stimuli by presenting ones that promote other behaviors and prevent presentation of ones that evoke the problem behavior.

Example: Fearful companion animal utilizing aggressive behaviors to escape the aversive stimulation is systematically desensitized to the problem stimuli, and escape/avoidance is no longer reinforcing. The aggressive behaviors become moot because the emotional response is changed. Exposure to the feared stimulus is minimized. Operant conditioning accompanies respondent conditioning procedures to promote empowerment and increase the animal’s repertoire of desirable behaviors. The companion animal becomes less fearful also when an exercise program, a nutritional support plan, and general empowerment training are instated and other stressful living conditions are reduced.

Level 2:

Shaping and response prevention

Strategy and explanation: Antecedent control and shaping with response prevention. Instate antecedent control procedures as in level 1. Gradually replace the problem behavior with a replacement behavior through positively reinforcing approximations to it in the environment in which the problem behavior occurred. Ensure success by making the choice of the desirable behavior more likely over the problem behavior.

Example: A dog that utilizes aggressive behaviors when exposed to novel people has approximations of prosocial behaviors positively reinforced in gradually increasing intensities of exposure to strangers (usually manipulating distance and orientation) so that the dog does not perform the aggressive behaviors. Aggressive behaviors are avoided, and the new behaviors are installed gradually by shaping and empowerment training.

Level 3:

Differential positive reinforcement

Strategy and explanation: Antecedent control and differential positive reinforcement. Instate level 1 antecedent control procedures. Positive reinforcement of desirable replacement behavior (DRI, DRO, DRA or DRL) and extinction of problem behaviors.

Example: A dog that barks for social attention has bringing a toy targeted for positive 

reinforcement and barking targeted for extinction. A parrot that screams for social attention has lower-volume verbal behaviors targeted for positive reinforcement and screaming targeted for extinction. Note, extinction should never be used outside of a differential reinforcement procedure.


Level 4:

Positive reinforcement and negative punishment

Strategy and explanation: Antecedent control, positive reinforcement of desirable behaviors, and negative punishment of problem behaviors. Instate level 1 antecedent control procedures. Positive reinforcement of desirable replacement behavior (DRI, DRO, DRA or DRL) and negative punishment of problem behaviors.

Example: A dog that barks excessively for social attention has sitting and a single bark targeted for positive reinforcement and barking more than once targeted for negative punishment, including perhaps a time-out protocol. A parrot that screams excessively for social attention has lower-volume verbal behaviors targeted for positive reinforcement and screaming targeted for negative punishment, including perhaps a time-out protocol, such as having people immediately leave the room.

Level 5:

Graded differential negative reinforcement

Strategy and explanation: Antecedent control and graded negative reinforcement of desirable behaviors and extinction of problem behaviors. Instate level 1 antecedent control procedures. Present the problem stimulus at increasingly intense levels of exposure in order to keep the exposure minimally aversive, and make removal of the stimulus contingent on a desirable behavior. Problem behavior is targeted for extinction (although intensity of exposure is manipulated in order to minimize these trials).

Example: A dog that utilizes aggressive behaviors in order to escape novel people has prosocial behaviors in the presence of gradually increasing intensities of exposure to the strangers reinforced with increased distance from them. The procedure is done gradually to keep the procedure minimally aversive and prevent setting the occasion for aggressive behaviors. Where aggressive behavior accidentally occurs, extinction is used.

Level 6:

Positive reinforcement and positive punishment

Strategy and explanation: Antecedent control, positive reinforcement of desirable

behaviors, and positive punishment of problem behaviors. Instate level 1 antecedent control procedures. Note that positive punishment should never be instated without consideration of reinforcers involved and must meet all other criteria for effective punishment.

Example: A dog that barks excessively has delivery of a shock made contingent on barking behaviors. Alternative behaviors such as sitting quietly or fetching a toy are targeted for positive reinforcement, and the barking behaviors decrease in strength (while alternative behaviors increase in strength).

The Pet Professional Guild

As members of PPG and in accordance with our Guiding Principles “Members understand Force-Free to mean, no shock, no pain, no fear, no physical force, no physical molding, no compulsion based methods are employed to train or care for a pet” It is also the belief that experienced trainers must begin their behavior change programs with the least invasive and least aversive training protocols necessary to change the problematic behavior. Education is one of the key goals of PPG so its members have access to resources and thus training tools that meet the needs of their clients in line with the Guilds Guiding Principles. Our future provisional member mentor programs will enable less experienced trainers to learn these training techniques and broaden their tool-kits.

Allowing Professional Autonomy

A professional must be allowed autonomy to work within the guidelines of his/her professional  code  of  practice.    PPG  members  are  encouraged  to  use  their  individual methods of choice from within governing principles and guidelines.   As a governing body, the PPG endeavours to choose well researched methods that are least intrusive and most effective in its information to members.

Together with the LIEBI model, PPG members can further determine the intrusiveness of their interactions with animals by considering the following, taken from Bailey & Burch6.

According  Dignity  Regarding  human  learners,  Bailey  and  Burch6   explain,  “Many  of  the clients that we serve are not able to effectively represent themselves.   They may be nonverbal or simply unable to get someone to listen to them.  If their wishes are unk nown and they are unable to make choices, they may become depressed and present behavior problems…”6.   This statement can also be used to guide direction for animal training methods.   Methods should allow choices that can be positively reinforced, further empowering the animal to progress.

Treating Others with Caring and Compassion  “If, as a behavior analyst (here read animal trainer), you respect the autonomy of clients (both human and non-human), work to benefit them, and devise programs that accord them dignity, you will automatically be treating clients with care and compassion” 6.  PPG members should actively factor this into method development and use.

Respecting Autonomy   “To respect one’s autonomy means to promote his or her independence or self-sufficiency”5.   Bailey and Burch say that “…prompting, shaping, chaining, fading and the use of conditioned reinforcers”6 aid self-empowerment but should be used judiciously to ensure safety at all times.   Although their book relates to human application of behaviour analysis, the same principle can be applied to animal training.

Maintenance of Best Practice

Without a prescribed method of determining best practice an organisation will flounder and/or diminish.   A willingness to adhere to the intervention model and principles stated above, with regular oversight by our caring, well-versed governors, the PPG will help guide animal trainers to maintain a standard of humane, effective best practice. This too will evolve with experience, like the behaviour of the animals we teach!
