Topic 1.3 Animal Welfare Assessment Frameworks

Assessing animal welfare is a complex process that requires more than observing whether an animal appears healthy or behaves appropriately. Contemporary welfare science recognises that welfare encompasses physical health, emotional wellbeing, behavioural expression, environmental quality and the animal’s overall quality of life. Because many aspects of welfare cannot be measured directly, structured assessment frameworks have been developed to guide consistent, evidence-based evaluation of an animal’s wellbeing.

Animal welfare assessment frameworks provide systematic approaches for gathering, interpreting and communicating information about an animal’s welfare status. Rather than relying on subjective impressions or isolated observations, these frameworks encourage practitioners to consider multiple indicators across physical, behavioural and environmental domains. They also facilitate communication between professionals by providing a common language for discussing welfare concerns and identifying priorities for intervention.

Several welfare assessment frameworks are used internationally within veterinary medicine, zoological management, agriculture, research and companion animal practice. Among the most influential are the Five Freedoms, the Five Domains Model and Quality of Life (QoL) assessments. Each framework has strengths and limitations, and each contributes valuable perspectives when evaluating assistance animal welfare.

Within occupational therapy assistance animal practice, welfare assessment should be integrated into routine clinical reasoning rather than viewed as a separate activity. Behavioural changes, alterations in work performance, reduced motivation, physical discomfort or environmental challenges may all indicate declining welfare and require further investigation. Early recognition enables timely intervention, helping to protect both the animal and the human partner.

Importantly, welfare assessment is not about determining whether an assistance animal is “good enough” to continue working. Instead, it is an ongoing process that identifies opportunities to optimise health, wellbeing and quality of life throughout the lifespan of the assistance animal partnership.

This chapter introduces the major welfare assessment frameworks used in contemporary animal care and explores how Occupational Therapists can incorporate structured welfare assessment into assistance animal practice.

Why Welfare Assessment Matters

Routine welfare assessment enables practitioners to identify concerns before they become significant health or behavioural problems.

Effective welfare assessment supports:

• early recognition of illness or injury
• identification of behavioural changes
• monitoring of emotional wellbeing
• evaluation of environmental suitability
• assessment of workload and fatigue
• evidence-based decision-making
• communication between professionals
• continuous welfare improvement.

For assistance animals, welfare assessment should occur throughout:

• selection
• training
• placement
• routine practice
• reassessment
• retirement.

The Five Freedoms

The Five Freedoms were developed during the 1960s and remain one of the best-known animal welfare frameworks.

They propose that animals should be:

• free from hunger and thirst
• free from discomfort
• free from pain, injury and disease
• free to express normal behaviour
• free from fear and distress.

The Five Freedoms were historically important because they shifted attention beyond preventing cruelty towards promoting basic welfare standards.

However, contemporary welfare science recognises that completely eliminating all negative experiences is neither possible nor necessarily desirable. Temporary discomfort, frustration or fear may occur naturally and can sometimes support learning, resilience and adaptation.

Consequently, newer welfare models place greater emphasis on promoting positive experiences rather than simply preventing negative ones.

The Five Domains Model

The Five Domains Model is widely regarded as the contemporary gold standard for animal welfare assessment and is particularly relevant to assistance animal practice.

The framework evaluates five interconnected domains:

Domain 1 – Nutrition

Considers:

• access to food
• water quality
• body condition
• nutritional adequacy
• feeding opportunities.

Domain 2 – Physical Environment

Includes:

• housing
• temperature
• rest areas
• transport
• environmental comfort
• opportunities for movement.

Domain 3 – Health

Considers:

• disease
• injury
• pain
• mobility
• physical fitness
• preventative healthcare.

Domain 4 – Behaviour

Examines:

• opportunities for natural behaviours
• social interactions
• play
• exploration
• environmental choice
• training experiences.

These four domains contribute to:

Domain 5 – Mental State

The fifth domain considers the animal’s likely emotional experiences, including:

Positive states:

• comfort
• confidence
• curiosity
• engagement
• contentment
• enjoyment.

Negative states:

• pain
• fear
• anxiety
• frustration
• loneliness
• boredom.

The Five Domains encourage practitioners to move beyond identifying problems and actively promote positive welfare experiences.

Quality of Life Assessments

Quality of Life (QoL) assessments evaluate how an animal experiences its overall life rather than focusing solely on individual health conditions.

Quality of life assessments often consider:

• physical comfort
• mobility
• appetite
• enjoyment of activities
• social relationships
• behavioural engagement
• emotional wellbeing
• ability to perform meaningful activities.

Quality of life assessments are particularly valuable when making decisions regarding:

• chronic illness
• ageing
• retirement
• palliative care
• end-of-life planning.

Rather than asking, “Is the animal healthy?”, Quality of Life assessments ask, “Is the animal experiencing a life worth living?”

Selecting Appropriate Assessment Tools

Different settings require different welfare assessment tools.

Occupational Therapists should select tools that are:

• evidence based
• appropriate for the species
• practical to administer
• reliable
• valid
• appropriate for the purpose of assessment.

Formal welfare assessments complement, rather than replace, behavioural observation, veterinary examination and interdisciplinary collaboration.

Integrating Welfare Assessment into Occupational Therapy Practice

Occupational Therapists may incorporate welfare assessment by routinely considering:

• changes in behaviour
• enthusiasm for work
• interaction with handlers
• willingness to perform tasks
• fatigue
• physical comfort
• environmental suitability
• work–rest balance.

When concerns are identified, Occupational Therapists should collaborate with trainers, veterinarians and other professionals to determine appropriate interventions.

Limitations of Welfare Assessment

Although structured frameworks improve consistency, welfare assessment remains partly interpretive.

Challenges include:

• individual variation
• species differences
• limited behavioural opportunities in some environments
• observer bias
• incomplete information
• changes over time.

For this reason, welfare should be assessed using multiple sources of information rather than relying on a single observation or assessment tool.

The Occupational Therapist’s Role

Occupational Therapists contribute to welfare assessment by:

• recognising behavioural and environmental indicators of welfare
• monitoring changes over time
• documenting observations
• communicating concerns appropriately
• supporting environmental modification
• advocating for positive welfare
• facilitating interdisciplinary collaboration.

Routine welfare assessment supports both occupational participation and the long-term sustainability of assistance animal partnerships.

Key Practice Principle

Animal welfare assessment is an ongoing, evidence-based process that integrates physical health, behaviour, environment and emotional wellbeing. Occupational Therapists should use structured welfare frameworks alongside clinical reasoning and interdisciplinary collaboration to support positive welfare outcomes throughout the lifespan of the assistance animal partnership.
