Professionally- and Self-Trained Service Dogs: Benefits and Challenges for Partners With Disabilities

2021 AAHA Working, Assistance, and Therapy Dog Guidelines

The guidelines are the first comprehensive consensus report on veterinary healthcare recommendations for working, assistance, and therapy dogs. This category of canine patients includes a broad assortment of animals, some with well-defined functions and others that provide a more generalized support role. The guidelines discuss recommendations for dogs trained for protection, odor/scent detection, service functions for people with diagnosed disabilities or physical limitations, emotional support, and therapeutic intervention. Although the term is often used to describe dogs providing animal-assisted activities, true therapy dogs provide goal-directed therapy, often under the supervision of a healthcare professional such as an occupational therapist or psychologist. Many working dogs undergo extensive training and have rigorous physical demands placed upon them. These factors make working, assistance, and therapy dogs inherently valuable and impose a need for a high level of primary veterinary care as described in the guidelines. Because working dogs have a particularly close relationship with their handlers, a trust relationship between the practice team and the working-dog client is imperative.

The "olfactory fingerprint": can diagnostics be improved by combining canine and digital noses?

A sniffer (detecting) dog is conventionally defined as an animal trained to use its olfactory perceptions for detecting a vast array of substances, mostly volatile organic compounds (VOCs), including those exceptionally or exclusively generated in humans bearing specific pathologies. Such an extraordinary sniffing performance translates into the capability of detecting compounds close to the femtomolar level, with performance comparable to that of current mass spectrometry-based laboratory applications. Not only can dogs accurately detect "abnormal volatilomes" reflecting something wrong happening to their owners, but they can also perceive visual, vocal and behavioral signals, which altogether would contribute to raise their alertness. Although it seems reasonable to conclude that sniffer dogs could never be considered absolutely "diagnostic" for a given disorder, several lines of evidence attest that they may serve as efficient screening aids for many pathological conditions affecting their human companions. Favorable results have been obtained in trials on cancers, diabetes, seizures, narcolepsy and migraine, whilst interesting evidence is also emerging on the capability of early and accurately identifying patients with infectious diseases. This would lead the way to proposing an "olfactory fingerprint" loop, where evidence that dogs can identify the presence of human pathologies provides implicit proof of the existence of disease-specific volatilomes, which can be studied for developing laboratory techniques. Contextually, the evidence that specific pathologies are associated with abnormal VOC generation may serve as reliable basis for training dogs to detect these compounds, even (or especially) in patients at an asymptomatic phase.

'Community members aren't aware that assistance animals come in all shapes and sizes, and help people with all kinds of disabilities' - Experiences of using assistance animals within community living in Australia

PURPOSE

This study aimed to investigate: (1) the characteristics of people using, or had previously used, assistance animals within community living in Australia; (2) positive and/or negative experiences of these users; and (3) educational resources that may aid public awareness.

MATERIALS AND METHODS

An online survey was distributed through Australian assistance animal organisations and social media channels. Past/current assistance animal users (n = 112) responded to questions on demographic and types of animal supports used, experience of assistance animal use, community attitudes experienced, and perspectives about the need for public education. Data were analysed with descriptive and inferential statistics. Content analysis provided additional insights of the positive and/or negative experiences assistance animal users had faced.

RESULTS

Nearly all participants used an assistance dog (n = 111), and 37 (33%) used the animal for more than one type of support. Seventy percent reported experiencing both positive and negative community attitudes/reactions. Length of time of having an assistance animal was associated with significantly higher prevalence of positive attitudes/reactions, whilst users who received medical support from the animal tended to experience more negative community attitudes/reactions than other users. The majority (90%) agreed that more public education is needed regarding assistance animal public access rights.

CONCLUSIONS

This study is the first in Australia to undertake a large-scale survey of assistance animal users with a range of disability types. It highlights the benefits and challenges of assistance animals, which could be useful to consider when determining the most appropriate support for an individual.Implications for RehabilitationThere are a range of possible benefits, but also challenges, in the use of assistance animals that should be considered when a person with disability or health conditions, or people advising them, are determining if an animal is the most appropriate support.Assistance animals can provide multiple types of support to one user, so could offer a potential cost-benefit beyond traditional assistive devices or other types of support.To ensure better inclusion of assistance animal users, public education is needed to promote community awareness of the types of animals that meet the definition of an 'assistance animal', and thus have public access rights.In Australia, a nationally consistent government approach to the regulation, accreditation and funding of assistance animals should be established with the aim to address the current fragmented or unfair investment approach and/or discrimination experienced by some individuals.

The effects of assistance dogs on psychosocial health and wellbeing: A systematic literature review

Beyond the functional tasks that assistance dogs are trained for, there is growing literature describing their benefits on the psychosocial health and wellbeing of their handlers. However, this research is not only widely disparate but, despite its growth, has not been reviewed since 2012. Our objective was to identify, summarize, and methodologically evaluate studies quantifying the psychosocial effects of assistance dogs for individuals with physical disabilities. Following PRISMA guidelines, a systematic review was conducted across seven electronic databases. Records were independently screened by two authors. Studies were eligible for inclusion if they assessed outcomes from guide, hearing, medical, or mobility service dogs, if they collected original data on handlers' psychosocial functioning, and if the outcome was measured quantitatively with a validated, standardized measure. Studies on psychiatric service dogs, emotional support dogs, and pet dogs were excluded. Of 1,830 records screened, 24 articles were identified (12 publications, 12 theses) containing 27 studies (15 cross-sectional, 12 longitudinal). Studies assessed the effects of mobility (18), hearing (7), guide (4), and medical (2) assistance dog partnerships with an average sample size of N = 83. An analysis of 147 statistical comparisons across the domains of psychological health, quality of life, social health, and vitality found that 68% of comparisons were null, 30% were positive in the hypothesized direction, and 2% were negative. Positive outcomes included significant effects of having an assistance dog on psychological wellbeing, emotional functioning, self-esteem, and vitality. However, it is of note that several methodological weaknesses of the studies make it difficult to draw any definitive conclusions, including inadequate reporting and a failure to account for moderating or confounding variables. Future research will benefit from stronger methodological rigor and reporting to account for heterogeneity in both humans and assistance dogs as well as continued high-quality replication.
