A Systematic Review of Dog-Assisted Therapy in Children with Behavioural and Developmental Disorders

Objectives Animal-assisted therapy with dogs is regularly used in children with behavioural and developmental disorders. Aims of this systematic review were threefold: to analyse the methodological quality of studies on dog-assisted therapy (DAT) for children with behavioural and developmental disorders, to determine to which extent the studies on DAT adhere to the quality criteria developed by the International Association of Human Animal Interaction Organisation (IAHAIO) and to describe the characteristics of the participants, the intervention and the outcomes. Method Three databases (i.e. PsycInfo, MedLine and Eric) were searched, and 14 studies on DAT were included. The Joanna Briggs Institute checklist (JBIC) and the quality criteria developed by the IAHAIO were used during data extraction. Characteristics of the participants, the intervention, the therapy dogs and the outcomes of the studies were summarised. Results Six of the 14 included studies reported significant outcomes of DAT, whereof six in the social domain and two in the psychological domain. However, scores on the JBIC indicated low to moderate methodological quality and only three of the included studies adhered to the IAHAIO quality criteria. Conclusions DAT is a promising intervention for children with behavioural and developmental disorders, especially for children with autism spectrum disorder. A clear description of the therapy’s components, the role of the therapy dog and analysis of the treatment integrity and procedural fidelity would improve the methodological quality of the studies and the field of dog-assisted interventions.

A Measurement Equivalence Study of the Family Bondedness Scale: Measurement Equivalence Between Cat and Dog Owners

About 38.4% of U.S. households include a dog, and 25.4% a cat, as pets, and a recent poll suggested over 90% of pet owners feel their companion animal is a family member. Numerous studies have suggested pet ownership has physical, mental, and social health benefits, though much of this research has yielded mixed results. Results of a recent review suggested significant measurement problems in human-animal interaction (HAI) and human-animal bond (HAB) research, including the absence of validity evidence, overly long measures, lack of evidence for measurement equivalence across species of pets, and measures lacking a basis in important psychological, family, and attachment theories. This article describes the development and results of a measurement equivalence study of a new measure of the HAB called the family bondedness scale (FBS). This scale, and the research results, address multiple gaps in HAB measurement. Results of multi-group confirmatory factor analyses with multiple covariates indicated the scores on the FBS showed equivalence between cat and dog owners. The use of the FBS in both veterinary research and practice, as well as in research and practice in other disciplines, such as social work and psychology, are considered.

Pet Ownership and Longitudinal Change in Physical Function: Evidence From the BLSA

Successful aging depends on avoiding disease and disability, maintaining high physical and cognitive function, and psychological adaptation. Research examining the relationship of pet ownership (PO) or human-animal interaction (HAI) to human health supports contributions to these successful ag-ing-related outcomes at some point in the life-cycle, mostly in populations with diseases or disabili-ties. We examine the contributions of PO to maintaining physical capacity among generally healthy community-dwelling older participants in the Baltimore Longitudinal Study of Aging (BLSA). Partici-pants’ [N=637, mean age=68.3 years (SD=9.6), pet owners N=149] completed a standardized physi-cal function test battery (among other measures) every 1-4 years and a ten-year PO history. Linear mixed, or generalized linear mixed, models with time varying PO were used to examine change in successful aging-related outcomes over up to 13 years [mean=7.5, (SD=3.6)] according to PO. Physi-cal function declined across all domains examined, but was observed to be less severe with PO in overall physical performance (p<0.001), rapid gait speed (p=0.041), 400-meter walk time (p<0.001), and reported physical wellbeing (p=0.032). No differences were observed for grip strength (p=0.56), usual gait speed (p=0.07), and leisure time physical activity (p=0.26) after con-trolling for age. This study provides the first longitudinal evidence that PO may promote successful aging among community-dwelling healthy older adults by moderating age-related declines in physical functional status in late-life.

Current Advances in Assessment of Dog’s Emotions, Facial Expressions, and Their Use for Clinical Recognition of Pain

Animals’ facial expressions are involuntary responses that serve to communicate the emotions that individuals feel. Due to their close co-existence with humans, broad attention has been given to identifying these expressions in certain species, especially dogs. This review aims to analyze and discuss the advances in identifying the facial expressions of domestic dogs and their clinical utility in recognizing pain as a method to improve daily practice and, in an accessible and effective way, assess the health outcome of dogs. This study focuses on aspects related to the anatomy and physiology of facial expressions in dogs, their emotions, and evaluations of their eyebrows, eyes, lips, and ear positions as changes that reflect pain or nociception. In this regard, research has found that dogs have anatomical configurations that allow them to generate changes in their expressions that similar canids—wolves, for example—cannot produce. Additionally, dogs can perceive emotions similar to those of their human tutors due to close human-animal interaction. This phenomenon—called “emotional contagion”—is triggered precisely by the dog’s capacity to identify their owners’ gestures and then react by emitting responses with either similar or opposed expressions that correspond to positive or negative stimuli, respectively. In conclusion, facial expressions are essential to maintaining social interaction between dogs and other species, as in their bond with humans. Moreover, this provides valuable information on emotions and the perception of pain, so in dogs, they can serve as valuable elements for recognizing and evaluating pain in clinical settings.

Anthropomorphism and Its Adverse Effects on the Distress and Welfare of Companion Animals

Anthropomorphic practices are increasing worldwide. Anthropomorphism is defined as the tendency to attribute human forms, behaviors, and emotions to non-human animals or objects. Anthropomorphism is particularly relevant for companion animals. Some anthropomorphic practices can be beneficial to them, whilst others can be very detrimental. Some anthropomorphic behaviors compromise the welfare and physiology of animals by interfering with thermoregulation, while others can produce dehydration due to the loss of body water, a condition that brings undesirable consequences such as high compensatory blood pressure and heat shock, even death, depending on the intensity and frequency of an animal’s exposure to these stressors. Malnutrition is a factor observed due to consumption of junk food or an imbalance in caloric proportions. This can cause obesity in pets that may have repercussions on their locomotor apparatus. Intense human–animal interaction can also lead to the establishment of attachment that impacts the mental state and behavior of animals, making them prone to develop aggression, fear, or anxiety separation syndrome. Another aspect is applying cosmetics to pets, though scientific studies have not yet determined whether cosmetic products such as coat dyes, nail polish, and lotions are beneficial or harmful for the animals, or to what extent. The cohabitation of animals in people’s homes can also constitute a public health risk due to infectious and zoonotic diseases. In this context, this paper aims to analyze the adverse effects of anthropomorphism on the welfare of companion animals from several angles—physiological, sanitary, and behavioral—based on a discussion of current scientific findings.

Penetrative and non-penetrative interaction between Laboulbeniales fungi and their arthropod hosts

Laboulbeniales are a highly specialized group of fungi living only on arthropods. They have high host specificity and spend their entire life-cycle on an arthropod host. Taxonomic characters of Laboulbeniales are based on the architecture of the cells of the parenchymal thallus, i.e. the visible part of the fungus outside the host. The extent of the fungus spreading inside the host—the haustorium—remains largely unknown. The attachment to the arthropod host is fundamental to understand the fungus-animal interaction, but how this truly occurs is unclear. Recent evidences question the strictly parasitic life-style of Laboulbeniales. We used micro-computed tomography (µCT) and 3D reconstructions to visualize, for the first time, the complete structure of Laboulbeniales species in situ on their hosts. We compared the haustoriate species, Arthrorhynchus nycteribiae on an insect host to the non-haustoriate species, Rickia gigas on a millipede host. Our results confirm that some Laboulbeniales species are ectoparasitic and have a haustorial structure that penetrates the host’s cuticle, while others are ectobionts and are only firmly attached to the host’s cuticle without penetrating it. The presence and the morphology of the haustorium are important traits for Laboulbeniales evolution, and key factors for future understanding of host dependence and specificity.

Integrating Enactive and Intercorporeal Approaches to Interaction and Interaction Analysis: d/Deaf Persons and Animals. In Search of the ‘In-Between’ and Adequate Methodologies

"How does understanding occur in encounters of living beings? What is experienced by the interaction partners and what happens in the ‘In-Between’? And how can this be captured? In this paper an enactive approach to interaction is proposed with the focus on reciprocal intercorporeal attunement and co-creation of meaning in a specific environment. As alternative framework this approach is applied to the interaction of d/Deaf persons and animals. In the interaction with an animal, verbal communication - which is challenging for d/Deaf persons - is of secondary importance, so this frame is well suited to focus on intercorporeal attunement. In the interaction discourse regarding d/Deaf persons as well as Human-Animal-Interaction the assessment of the interaction process as such and embodied research methodologies are scarcely to be found. With the enactive approach new perspectives on the mechanisms of interaction and the influencing conditions can be opened as well as new approaches to respective research options.

Therapy Dog Welfare Revisited: A Review of the Literature

During the past decade, the field of human–animal interaction(s) research has been characterized by a significant increase in scientific findings. These data have contributed to our current understanding of how humans may benefit from contact with animals. However, the animal experience of these interactions is still an under-researched area. This paper addresses the welfare of dogs who participate in animal-assisted interventions (AAIs) to improve health in human recipients. This paper builds on previous work by Glenk (2017) and provides an updated review of the literature on therapy dog welfare published from 2017–2021. New advances in scientific methodology, such as the determination of salivary oxytocin, breath rate and tympanic membrane temperature, are analyzed regarding their value and limitations for research in AAIs. Moreover, welfare-related social and environmental factors (e.g., freedom of choice, exploration of novel environments, inequity aversion, individual development, working experience, relationship with handler and handler skills) that profoundly influence dog perception and well-being are reviewed and discussed. Accounting for the globally increasing interest and the number of dogs utilized in AAIs, safeguarding therapy dog well-being, and identifying situations, circumstances and protocols that may challenge animal welfare remains an emerging and crucial area of scientific effort.

Conceptualizing Indigenous Human–Animal Relationships in Aotearoa New Zealand: An Ethical Perspective

This article considers the complexity and diversity of ethical concepts and beliefs held by Māori, the indigenous people of Aotearoa New Zealand (hereafter New Zealand), relating to animals. A combination of interviews and focus group discussions were conducted with individuals who identify as Māori and were working with wildlife, primarily in an eco-tourism and conservation context. Two main themes emerged from the data: ethical concepts relating to the environment, and concepts relating to the spiritual relationships between people, animals and the environment. These findings highlight that the connections between humans and animals through a Māori lens are nuanced in ways not typically accounted for in Western philosophy. This is of particular importance because of the extent to which standard Western thought is embodied in law and policy related to human treatment of animals and the environment. In New Zealand, relationships and partnerships are informed by Te Tiriti ō Waitangi, one of New Zealand’s founding documents. Where these partnerships include activities and environments involving human–animal interaction, policy and legislation should account for Māori knowledge, and diverse of thought among different hapū (tribal groups). We conclude by exploring ways of including Māori ethical concepts around animals in general, and wild animals in particular, in law and policy, providing a case study relevant to other bicultural or multicultural societies.
