The significance of this information is most effectively considered in light of the natural history, environmental conditions, and individual variation to which each animal is inextricably linked.<sup>2<\/sup><\/p>\n<p>Animals have diverse natural histories, with distinctive biological, psychological, and environmental needs that must be addressed and regarded. Taken together, these factors can provide insight into the needs of individual animals, and must be incorporated into the development of appropriate shelter environments.

The Farm Animal Welfare Council refined the report\u2019s concepts into the Five Freedoms.6 These freedoms are defined as ideal states, as opposed to basic standards:<sup>6<\/sup><\/p>\n<p>1. Freedom from thirst, hunger, and malnutrition<\/p>\n<p>2. Freedom from discomfort<\/p>\n<p>3. Freedom from pain, injury, and disease<\/p>\n<p>4. Freedom to express normal behavior<\/p>\n<p>5. Freedom from fear and distress<\/p>\n<h2>DEFINING WELFARE<\/h2>\n<p>According to the literature, animal welfare can be defined as concerns, intentions, and actions that arise from, and are aligned with, an ethical responsibility to:<sup>7-10<\/sup><\/p>\n<ul>\n<li>\u00a0Minimize and\/or alleviate animal suffering<\/li>\n<li>\u00a0Maximize each animal\u2019s physical and psychological well-being<\/li>\n<li>\u00a0Improve animals\u2019 ability to cope with the challenges of captive environment<\/li>\n<li>\u00a0Recognize animals\u2019 ability to express species-typical behaviors<\/li>\n<li>\u00a0Sustain animals\u2019 ability to maintain some measure of control over their environment.<\/li>\n<\/ul>\n<p>There has been some contention with definitions of welfare, attributable mainly to the subjective nature of psychological well-being, and the inherent difficulty of appreciating the lived experience of \u201can other.\u201d Concepts, such as ability to cope and discerning levels of suffering, are difficult to objectively measure, and individual animals may vary in the extent of environmental control required for well-being. Moreover, subjective experiences and states are not always easily defined or assessed. In this light, it is often suggested that a multifaceted approach of behavioral, physical, psychological, and physiological measures is required for an authentic evaluation of animal welfare.<sup>4,7,8,10<\/sup><\/p>\n<h2>MEASURING WELFARE<\/h2>\n<p>Welfare measures are numerous and include physiological, psychological, health, and behavioral components. They are used as indicators of poor quality of life, inclusive of stress, pain, and\/or suffering.<sup>10,11<\/sup><\/p>\n<h3>Stress<\/h3>\n<p>Stress becomes a welfare issue when an animal\u2019s inability to cope with the challenges of the shelter environment jeopardizes its health and well-being.<sup>10,12<\/sup><\/p>\n<p>Inappropriate environmental conditions and poor welfare may compromise immune function and increase susceptibility to disease, which endangers shelter populations.<\/p>\n<p>Stress can be measured through the use of biological and psychological markers, such as cortisol, reproductive hormone levels, heart rate, body temperature, and immunological markers.<sup>4,13<\/sup> It can sometimes be mitigated by providing captive animals with some measure of real or perceived control over their environment. Unfortunately, most animals entering the shelter environment experience stress due to the unfamiliarity of surroundings, situation, and social factors of a novel environment.<\/p>\n<h3>Suffering<\/h3>\n<p>Suffering has been defined as prolonged or intense negative emotional states, such as pain, fear, anxiety, or frustration, occurring independently or concurrently.<sup>14,15<\/sup> An animal can be in \u201cgood health\u201d and still be suffering. Thus, suffering is often differently experienced and expressed across species and individuals.<sup>16<\/sup><\/p>\n<p>A primary goal of welfare is to decrease\/alleviate suffering. Marian Dawkins has posited that 2 core questions should be posed relevant to alleviating suffering and increasing welfare: First, can animals\u2019 health be improved? Second, are the animals being provided something they need and\/or want?<sup>2,13<\/sup> Need and\/or want can be approached by providing animals the ability to perform species-specific behaviors as well as affording animals some measure of choice and control in their environment.<\/p>\n<p>Welfare assessment can be challenging because it is interpretive and relies, in part, on human valuation.<sup>16<\/sup> Thus, it becomes clear that questions about welfare are fundamental, yet difficult to address and resolve.<\/p>\n<h2>DEVELOPING WELFARE<\/h2>\n<h3>Progress &amp; Innovations<\/h3>\n<p>Animal shelters have made great progress since the 1800s, when their function was primarily to dispose of unwanted animals.<sup>17,18<\/sup> Modern animal shelter veterinarians and staff work to ensure the animals\u2019 physical and psychological health, incorporate welfare innovations, and provide humane care.<\/p>\n<p>Goals and services of shelter veterinary health and welfare practices have expanded to include:<sup>17,18<\/sup><\/p>\n<ul>\n<li>\u00a0Humane care, handling, and\/or housing of unwanted, homeless animals<\/li>\n<li>\u00a0Adoption services<\/li>\n<li>\u00a0Animal behavior\/training<\/li>\n<li>\u00a0Individual and population animal health\/disease management<\/li>\n<li>\u00a0Overpopulation management<\/li>\n<li>\u00a0Emergency disaster response<\/li>\n<li>\u00a0Public health protection (eg, zoonoses)<\/li>\n<li>\u00a0Veterinary forensics<\/li>\n<li>\u00a0Active community outreach and partnerships.<\/li>\n<\/ul>\n<h3>Challenges<\/h3>\n<p>Shelter veterinary medicine yields some challenges distinct from clinical veterinary practice. For example, shelter veterinarians are in the unique position of being required to practice both individual and population medicine; however, the health and welfare of the shelter population takes precedence.<sup>19<\/sup><\/p>\n<p>Impediments to population welfare often stem from the fact that shelters must maximize welfare within a limited environmental space, with limited funding, while still allowing for healthy animal population dynamics and interaction with the public.19 Additionally, stringent regulatory standards for shelter animal care are lacking, which, if coupled with inadequate resources and poor staff training, can further complicate the goals of optimal care and welfare.<sup>4,19,20<\/sup><\/p>\n<p>Other welfare challenges arise from:<sup>4,19,20<\/sup><\/p>\n<ul>\n<li>\u00a0Housing and environmental conditions<\/li>\n<li>\u00a0Diet\/nutrition<\/li>\n<li>\u00a0Restriction of space and\/or movement constraints<\/li>\n<li>\u00a0Lack of environmental control<\/li>\n<li>\u00a0Lack of social contact<\/li>\n<li>\u00a0Discordant social groupings<\/li>\n<li>\u00a0Inability to hide and\/or express antipredator behavior<\/li>\n<li>\u00a0Chronic fear<\/li>\n<li>\u00a0Individual animal considerations, such as medical or behavioral problems.<sup>2<\/sup><\/li>\n<\/ul>\n<p>Shelter veterinary medicine plays an essential role in addressing these challenges by evaluating and maintaining the physiological, behavioral, and psychological health of shelter animals.<\/p>\n<h2>IMPLEMENTING WELFARE<\/h2>\n<h3>Behavior<\/h3>\n<p>Evolutionary history influences the behavior of a given species and leads to species-specific behaviors.<sup>2<\/sup> These motivations persist even when the captive environment prevents animals from performing such behaviors, resulting in frustration for the animal.<sup>2<\/sup> Behavioral considerations include reasons for behavioral displays and the performance of these behaviors. For shelter animals, it must be determined which behaviors cannot be executed, why they cannot be performed, and what effect this has on the animal.<sup>4<\/sup>\u00a0In other words, how does the animal respond when highly motivated species-specific behaviors are not possible?<\/p>\n<p>Frustrated motivations and lack of control can yield numerous changes in behavior. <sup>5,22-24<\/sup><\/p>\n<ul>\n<li>\u00a0<strong>Displacement behavior<\/strong> is purposeful activity apparently unrelated to the frustrating stimulus (eg, grooming when denied access to food).<\/li>\n<li>\u00a0<strong>Aggression<\/strong> can occur when behavioral frustration leads to increased hostility toward conspecifics.<\/li>\n<li>\u00a0<strong>Vacuum behaviors<\/strong> are actions performed in the absence of a stimulus.<\/li>\n<li>\u00a0<strong>Stereotypic behaviors<\/strong> can be generally defined as maladaptive, repetitive, and abnormal movements and actions, such as pacing, weaving, circling, excessive barking; all of which can have negative consequences on the adoptability of shelter animals.<sup>24-26<\/sup><\/li>\n<li>Other abnormal behaviors include self-harming, regurgitation, and ingestion.<\/li>\n<\/ul>\n<p>The causes of behavior change must be evaluated with caution, as they may arise from psychological causes, yet often signal an underlying health issue.<sup>23<\/sup> In particular, stereotypic behavior can suggest compromised welfare when related to frustration, inability to cope, and\/or brain dysfunction.<sup>24,25<\/sup> However, while stereotypes may be a viable measure of stress in many captive species, not all express these behaviors. It has also been theorized that stereotypic behaviors may serve as an important coping mechanism for shelter animals and it is important to view these behaviors within a more broadly-based assessment of welfare.<sup>25-26<\/sup><\/p>\n<p><strong>Enrichment<\/strong><\/p>\n<p>Environmental enrichment is an ongoing process that is species, and perhaps individually, variant over time. Variables from the species\u2019 natural history and the captive environment must be carefully evaluated for enrichment implications.<sup>20<\/sup> Enrichment implementation, such as group animal housing, is not without risk for injury, illness, or harm; thus, safety evaluation and monitoring is crucial.<sup>4<\/sup><\/p>\n<p>Enrichment can be divided into 5 categories:<sup>27,28<\/sup><\/p>\n<p>1. Food-based<\/p>\n<p>2. Physical habitat<\/p>\n<p>3. Sensory (visual, auditory, olfactory, tactile)<\/p>\n<p>4. Social (human\/nonhuman interaction)<\/p>\n<p>5. Cognitive (problem solving).<\/p>\n<p>Providing confined animals with some measure of control over their environment by providing them the ability to choose enrichments has been shown to improve welfare:<sup>28<\/sup><\/p>\n<ul>\n<li>Innovative feeding enrichment devices, such as feeding enrichment toys, enable control and help stimulate cognitive and sensory aspects of enrichment.<\/li>\n<li>Pheromone spray can incorporate olfactory interest into an environment sterilized to minimize disease transmission.<\/li>\n<li>Music can provide auditory stimulation and visual sense can be enhanced through windows\/screens in habitat space.<\/li>\n<li>Training and human\u2013animal bonding can be cognitively and socially stimulating for animals that enjoy human contact, and are important to increasing adoption rates.<\/li>\n<\/ul>\n<h2>WELFARE AS ORGANIZATIONAL GOAL<\/h2>\n<p>Concerns for shelter animal welfare have fostered considerable efforts to improve conditions in shelter management programs. However, budgetary constraints and\/or knowledge gaps can limit the extent to which welfare concerns can be met.<sup>19<\/sup><\/p>\n<p>Shelter animal care and management programs designed to produce high levels of welfare should engage in:<sup>4,27-29<\/sup><\/p>\n<ul>\n<li>High-quality veterinary care<\/li>\n<li>Enrichment for the animals<\/li>\n<li>Shelter staff training and education<\/li>\n<li>Research and education related to updated standards of care, management, and advocacy issues<\/li>\n<li>Leadership implementation and improved communication<\/li>\n<li>Establishing a system of planning, accurate and consistent documentation, evaluating, and regulating shelter care and management.<sup>4,29<\/sup><\/li>\n<\/ul>\n<p>Shelter veterinarians play an important role in developing and evaluating management and enrichment methods. The needs of each animal should be evaluated, and balanced in accordance with population requirements and enrichment programs tailored to accommodate changing needs over time. In light of this, successful health care and welfare management requires collaboration and communication among shelter veterinarians, staff, behaviorists, trainers, and researchers.<sup>4,29<\/sup><\/p>\n<h2>ENSURING WELFARE<\/h2>\n<p>Modern shelters are fulfilling an increasing role in society due to their expertise, outreach, and health management programs. As a whole, their missions focus upon humane care and public protection. However, scientific research, education, and enhanced shelter programs are improving the welfare of shelter animals and contributing to the overall body of knowledge about shelter species, animal behavior, welfare, and companion animals.<\/p>\n<p>Education and public participation in activities raise awareness of the difficulties faced by shelters and shelter animals. It is important to cultivate reverence for these animals, and the educational opportunities and interactions within the shelter and community should incorporate this goal, as it is our duty to ensure the humane care and wellbeing of the animals in our charge.<\/p>\n<h2>AN ETHICAL ISSUE: POUND SEIZURE<\/h2>\n<div>\n<p>In addition to concerns regarding health and welfare, shelters have had their share of ethical controversies.<\/p>\n<p>One example is pound seizure\u2014the procurement of animals from pounds\/shelters for use in research. Shelters remain a subideal welfare situation for many animals despite welfare and care improvements. Shelters face challenges of overcrowding, and long-term confinement of unadoptable animals, or euthanasia. It has been argued that these unwanted\/unclaimed animals should be used to assist \u201cthe good of humanity\u201d through research.<sup>21<\/sup><\/p>\n<p>However, a portion of the American public does not approve of the resale of shelter animals for research.<sup>21<\/sup> Increasing public awareness and disapproval of these practices helped lead to the referral of the Pet Safety and Protection Act of 2009 to the House Committee on Agriculture to more strictly regulate procurement practices to help assuage public discontent.<sup>21<\/sup><\/p>\n<p>While society may help determine what is ethically acceptable, organizational efforts, such as those of the American Veterinary Medical Association, Association of Shelter Veterinarians, American Society for the Prevention of Cruelty to Animals, Animal Welfare Institute, Universities Federation for Animal Welfare, and Humane Society of the United States, are important in the development of research and education to inform the public and policy makers to promote responsible practices and management guidelines.<\/p>\n<\/div>\n<h3><span style=\"line-height: 1.5\">Acknowledgements<\/span><\/h3>\n<p>The author is grateful for the intellectual insight of Drs.
