Occupational therapy has long recognised that participation does not occur in isolation.

A person’s ability to engage in meaningful occupations is influenced by the interaction between:

• personal characteristics;
• abilities and challenges;
• environments;
• social expectations;
• available supports;
• occupational demands.

Within assistance animal practice, this principle is particularly important because the animal does not operate independently of the person’s life.

An assistance animal may have excellent training and the person may have genuine disability-related needs, but the partnership may still be unsuccessful if the surrounding environment does not support sustainable participation.

Therefore, occupational therapists must assess not only:

“Can an assistance animal perform this role?”

but:

“Will an assistance animal realistically improve participation within this person’s actual life circumstances?”

Moving Beyond the Individual: The Importance of Context

A common mistake in assistance animal discussions is focusing only on the person and the animal.

However, occupational therapy requires consideration of the broader context.

An assistance animal partnership is influenced by:

• the home environment;
• family and household members;
• education or workplace settings;
• community access;
• transport;
• finances;
• cultural considerations;
• existing supports;
• other animals in the household.

The same assistance animal may be highly successful in one environment and unsuitable in another.

Environmental Assessment Before Recommendation

Before recommending an assistance animal, the OT should consider the environments where the animal will be expected to function.

This may include:

Home Environment

Consider:

• Is the home suitable for the animal?
• Is there adequate space?
• Are there safety concerns?
• Are there other animals?
• Are household members supportive?
• Who contributes to animal care?

An assistance animal is not simply brought into the home; it becomes part of the household system.

Education Settings

For children and students, consider:

• school policies;
• staff understanding;
• peer interactions;
• classroom environment;
• supervision requirements.

An assistance animal may support participation, but it may also introduce new challenges.

For example:

A child may benefit from an assistance animal during transitions but experience increased distraction, attachment difficulties or reduced independence if the role is not carefully considered.

Workplace Environment

Consider:

• employer expectations;
• workplace culture;
• physical environment;
• safety requirements;
• travel requirements;
• reasonable adjustments.

The question is not only whether the animal can enter the workplace, but whether the partnership enables meaningful occupational participation.

Community Environments

Assistance animals frequently work in unpredictable environments.

Consider:

• public transport;
• shopping centres;
• healthcare environments;
• recreational activities;
• social settings.

The OT should consider whether these environments align with:

• the person’s goals;
• the animal’s capabilities;
• available supports.

Family and Household Considerations

An assistance animal affects more than the individual handler.

This is especially important where:

• the handler is a child;
• multiple family members have disabilities;
• multiple assistance animals are present;
• family members provide care support.

Consider:

• Who is responsible for daily care?
• Who manages veterinary appointments?
• Who provides backup support?
• How will routines change?
• Are family members willing and able to participate?

Multiple Assistance Animals Within One Household

Multiple assistance animals within a household require careful consideration.

Each partnership should not be assessed in isolation.

The OT should consider:

• interactions between animals;
• household capacity;
• competing needs;
• caregiver availability;
• financial sustainability.

Where multiple children have assistance animals, practical planning is particularly important.

A common consideration is whether there is sufficient adult capacity to safely support each partnership.

For example:

A household with two children requiring assistance animals may need to consider whether:

• one adult can realistically manage two working animals simultaneously;
• each child has adequate individual support;
• animal welfare needs can be met consistently.

The issue is not whether multiple assistance animals are impossible.

The issue is whether the household system can sustainably support them.

Neurodivergent Families and Environmental Complexity

Neurodivergent families may require particular consideration because household systems can be highly interconnected.

For example:

A child may benefit from an assistance animal, but the OT should consider:

• sensory needs of the child;
• sensory needs of siblings;
• routines;
• family stress;
• attachment patterns;
• behavioural interactions.

It is not uncommon for an animal placed into a neurodivergent household to be returned shortly after placement because:

• the child and animal increase each other’s dysregulation;
• the animal’s needs create additional stress;
• household routines become unsustainable.

This does not mean assistance animals are inappropriate for neurodivergent people.

It means the fit between the person, animal and environment must be carefully considered.

Cultural and Personal Context

Occupational therapy requires culturally responsive practice.

Consider:

• beliefs about animals;
• family roles;
• cultural expectations;
• religious considerations;
• community environments.

For example:

Some individuals or families may have cultural or religious beliefs affecting:

• animal contact;
• household roles;
• community participation.

These considerations do not automatically exclude an assistance animal, but they are important parts of informed decision-making.

Financial and Practical Sustainability

An assistance animal creates ongoing responsibilities.

Assessment should consider:

• veterinary expenses;
• food;
• grooming;
• equipment;
• training;
• insurance where relevant;
• emergency care.

Funding systems may not cover all aspects of animal ownership.

Therefore, the OT should explore:

• Is the partnership financially sustainable?
• What happens if unexpected costs occur?
• Who provides care if the person becomes unwell?

The Environment Can Determine Whether a Good Match Becomes a Successful Partnership

A highly suitable animal may struggle in an unsuitable environment.

Examples:

A calm, well-trained dog may not succeed if:

• the household cannot maintain routines;
• expectations are unrealistic;
• there is insufficient support.

Conversely, an animal with average abilities may thrive when:

• expectations are appropriate;
• the environment is supportive;
• the partnership is well matched.

The intervention outcome depends on the whole system.

Case Example: Environmental Mismatch

Scenario

A teenager with anxiety is considered for an assistance dog.

The dog is appropriately trained and the teenager has clear goals.

However, assessment identifies:

• family members are unable to support care;
• the home environment is highly unpredictable;
• the teenager struggles with responsibility for routines;
• the dog increases rather than decreases stress.

The OT does not conclude:

“The person cannot have an assistance dog.”

Instead, the OT identifies that:

• further preparation may be required;
• additional supports may be needed;
• the timing may not currently be appropriate.

The issue is not the person’s worthiness.

The issue is environmental fit.

Occupational Therapist Considerations

Occupational therapists should:

• assess the environment, not just the individual;
• consider the whole household system;
• explore practical sustainability;
• assess supports and responsibilities;
• identify environmental barriers;
• consider whether modifications or preparation are required;
• recognise that partnership success depends on person–environment–animal fit.

Key Practice Principles

1. Assistance Animals Exist Within Systems

The person, animal and environment cannot be separated.

2. Functional Assessment Must Include Context

A task is only meaningful if it improves participation in real life.

3. Good Animals Can Fail in Poorly Matched Environments

Suitability depends on the whole partnership.

4. Family and Support Systems Matter

Care capacity must be considered without unfairly excluding people who need assistance.

5. Environmental Assessment Supports Animal Welfare

A sustainable environment benefits both the person and the animal.

6. The Goal Is Meaningful Participation

The purpose of an assistance animal is not simply access, but improved occupational outcomes.

Environmental fit is one of the most important predictors of assistance animal partnership success. Occupational therapists contribute unique expertise by considering the interaction between the person, animal and environment, ensuring recommendations are not based solely on disability or animal capability but on whether the partnership can sustainably support meaningful participation within the person’s real-world life.
