What Happens to Shelter Dogs? An Analysis of Data for 1 Year From Three Australian Shelters

Annually, welfare shelters admit many dogs, including those whose caregivers surrender them or dogs who are strays. This article analyzes admission data from 3 metropolitan Australian shelters. The study collected data for a 1-year period and analyzed them to identify the characteristics of the typical shelter dog; patterns of relinquishment, sales, reclamation and euthanasia; and duration of stay and reasons underlying euthanasia, relinquishment, and postadoptive return. The study tracked more than 20,000 admissions during this period. To facilitate reclamation, the local Code of Practice requires a mandatory holding period for stray dogs; assessment for suitability for rehoming then occurs. Dogs failing the assessment are euthanized. Surrendered dogs can be assessed immediately. The Code of Practice also recommends that unsold dogs be euthanized 28 days postassessment. Typically, shelter dogs in Melbourne are strays, sexually entire, adult, small, and-usually-male. The majority of admissions are reclaimed or sold. Most reclamations occur within 4 days, and postadoptive return rates are low. That current desexing messages do not appear to have reached the owners of stray dogs to the same extent as they have other dog owners is a major finding, suggesting that a targeted education campaign may be required.

Reforging the bond—towards successful canine adoption

Abstract While most human–canine relationships are very fulfilling others fail, resulting in a large number of animals being abandoned or relinquished to animal shelters each year. This paper reviews our current understanding of the canine relinquishment and adoption process, with the aim of identifying those areas in which research is incomplete or absent. In order to achieve this aim, the process of canine ownership, relinquishment and adoption is broken down into a number of logical stages, which are then evaluated separately. The areas reviewed include the reasons why people acquire dogs, factors involved in their relinquishment, the effects of shelter admission upon canine behaviour, the evaluation of a dogs potential for adoption, characteristics of adopters, factors influencing a prospective adopters choice and problems which may be experienced post-adoption. The review identifies deficiencies in our current knowledge and indicates valid directions for future research.

Measuring executive dysfunction in an acute rehabilitation setting: Using the dysexecutive questionnaire (DEX)

It is recognized that existing neuropsychological measures of executive dysfunction lack adequate sensitivity and selectivity. While attempts have been made to develop improved measures, these have not yet been of great value to those who need to accurately identify executive deficits in a clinical setting. Several behavioral rating scales have been developed for this reason, including the 20-item Dysexecutive Questionnaire (DEX), which forms part of the Behavioral Assessment of the Dysexecutive Syndrome (BADS) test battery. To investigate the ability of the DEX to identify executive dysfunction in an acute rehabilitation setting, the BADS was administered to 64 persons who had sustained traumatic brain injury. It was found to be almost as sensitive to executive dysfunction, as measured by the total score obtained on the BADS battery, as an extended 65-item version of the scale, when completed by either the occupational therapist or clinical neuropsychologist working with each patient. Family members and the patient themselves provided, as expected, less accurate information. Our results indicate that the DEX can be used with some confidence as a screening instrument to identify executive dysfunction in an acute rehabilitation setting, provided it is completed by professional personnel, trained to be sensitive to the cognitive and behavioral concomitants of this disorder.

Assessment of executive dysfunction following traumatic brain injury: Comparison of the BADS with other clinical neuropsychological measures

Traditional neuropsychological measures of executive dysfunction (ED) are widely believed to lack adequate sensitivity and selectivity. This may indicate that existing measures are poorly designed and constructed, although an alternative explanation is that executive cognition is multifactorial, such that its assessment necessarily requires administration of multiple measures. This possibility led to the development of a test battery, the Behavioural Assessment of the Dysexecutive Syndrome (BADS). To investigate the sensitivity of the BADS to ED, it and various other measures of ED were administered to 64 persons who had sustained traumatic brain injury. The treating clinical neuropsychologist and occupational therapist for each participant also completed a behavioural rating scale, the Dysexecutive Questionnaire (DEX). Four factors were found to underlie scores on the neuropsychological measures, but few tests were sufficiently powerful to make a significant unique contribution to predicting scores on the DEX. This confirms that multiple tests, drawn from both the BADS and other sources, may be necessary to detect ED in a clinical population.

Perpetration-induced traumatic stress in persons who euthanize nonhuman animals in surgeries, animal shelters, and laboratories.

This study explored possible identification of Perpetration-induced Traumatic Stress (PITS) in workers whose occupations required euthanizing nonhuman animals and determining whether event or person-related factors influenced symptoms. The sample included 148 animal workers: veterinarians, veterinary nurses, and research and animal shelter staff. The Impact of Event Scale-Revised (IES-R) assessed traumatic stress. Experimenters constructed additional scales measuring satisfaction with social support, participation in various types of training, and concern over animal death. More than 70% of participants reported affinity toward animals had strongly influenced their occupation selection. Half the sample perceived animal death--particularly euthanasia--as one of the least desirable jobs. Of the sample, 11% reported experiencing moderate levels of traumatic symptoms. The study found lower levels of euthanasia-related stress were associated with increased satisfaction with social support and length of time working with animals. Those who reported high levels of concern about animal death reported higher levels of euthanasia-related stress. The study found occupational context was not associated with different levels of euthanasia-related stress symptoms--even though reasons for administering euthanasia differed significantly between occupations.

Cyclosporin A, an inhibitor of calcineurin, impairs memory formation in day-old chicks

Considerable evidence exists that changes in the phosphorylation state of neuronal proteins are correlated with learning and that inhibition of various protein kinases disrupts memory formation. Given the reversible nature of protein phosphorylation, a role for protein phosphatases in memory processing also seems likely. It has been shown recently that administration of the phosphatase inhibitor, okadaic acid, disrupts memory formation in day-old chicks, with retention deficits first appearing at approximately 40 min post-training [93]. In the present study the intracranial administration of the immunosuppressant cyclosporin A was also found to produce retention deficits in day-old chicks trained on a single-trial, passive-avoidance task, but the deficits were not significant until 85 min post-training. The difference could not be attributed to differences in the pharmacokinetics of the drugs. Since okadaic acid preferentially inhibits protein phosphatases 1 and 2A, while cyclosporin A is reported to inhibit only the Ca2+/calmodulin-dependent protein phosphatase, calcineurin, it is possible that different phosphatases may be involved in distinct stages of memory formation, as has been reported previously for protein kinases. The possibility that cyclosporin A may, in addition, act through inhibition of cyclophilins peptidyl-prolyl-cis/transisomerase activity is also canvassed.

Behaviors and attitudes towards semi-owned cats

ABSTRACT The intentional provision of food, medical treatment and shelter by humans for a cat that is not considered to be owned by the individual is defined as “semi-ownership.” The aim of this study was to explore the prevalence of such behaviors and the attitudes held by individuals who engage in them. The sample, comprising 424 residents from rural and non-rural Victoria, Australia, were surveyed in relation to their ownership status, practices, and attitudes towards companion animals. The findings revealed that 22% of the sample engaged in one or more cat semi-ownership behaviors; primarily feeding. Cat semi-ownership was associated with positive feelings towards cats, and the belief that cats are independent. Opportunities to engage cat semi-owners in education programs that promote responsible companion animal ownership behaviors were evident.

Development of the Monash Dog Owner Relationship Scale (MDORS)

Abstract With increasing scientific and clinical attention being paid to the formation, nature and consequences of human–companion animal relationships, there is a need to develop scales with which to assess such relationships in a rigorous, empirically valid manner. Accordingly, the aim in this study was to develop a psychometrically sound, multi-dimensional questionnaire with which to assess human–companion dog relationships. A multi-step process involving over 1,000 participants resulted in the development of a scale with 28 items, the Monash Dog Owner Relationship Scale or MDORS. The MDORS has three sub-scales, Dog–Owner Interaction, Perceived Emotional Closeness, and Perceived Costs, that appear to be relatively stable and interpretable across participant groups and that appear to represent important and diverse aspects of the human–companion dog relationship. It is envisaged that the future use of this scale will allow researchers to significantly increase our understanding of human–companion dog relationships by permitting direct comparisons across participant groups drawn from different demographic or cultural contexts. It may also permit clinicians to analyze relationships between dog owners and their dogs in more detail and depth than is possible using existing scales.

The impairment of long-term memory formation by the phosphatase inhibitor okadaic acid

While there is considerable evidence that protein kinase activity is involved in memory formation, there has been, as yet, no direct investigation of a role for protein phosphatases. However, phosphatases have been implicated in the effects of the activation of glutamate receptors of the NMDA type, in long-term depression, and in the regulation of transmitter release and membrane ion channel activities, phenomena which have been shown to be possibly involved in cellular memorial processes. In the present paper, inhibition of protein phosphatase by 0.5 nM okadaic acid, a selective inhibitor of phosphatases 1 and 2A, is demonstrated to prevent memory consolidation in day-old chicks trained on a single trial passive avoidance task. Retention losses first occurred after 30 min post-learning, at an intermediate stage of memory formation preceding a protein synthesis-dependent long-term stage. It is suggested that protein phosphatase activity is involved in precursor processes to long-term memory consolidation.

Current perspectives on attachment and bonding in the dog–human dyad

This article reviews recent research concerning dog–human relationships and how attributes that arise from them can be measured. It highlights the influence of human characteristics on dog behavior, and consequently, the dog–human bond. Of particular importance are the influences of human attitudes and personality. These themes have received surprisingly little attention from researchers. Identifying human attributes that contribute to successful dog–human relationships could assist in the development of a behavioral template to ensure dyadic potential is optimized. Additionally, this article reveals how dyadic functionality and working performance may not necessarily be mutually inclusive. Potential underpinnings of various dog–human relationships and how these may influence dogs’ perceptions of their handlers are also discussed. The article considers attachment bonds between humans and dogs, how these may potentially clash with or complement each other, and the effects of different bonds on the dog–human dyad as a whole. We review existing tools designed to measure the dog–human bond and offer potential refinements to improve their accuracy. Positive attitudes and affiliative interactions seem to contribute to the enhanced well-being of both species, as reflected in resultant physiological changes. Thus, promoting positive dog–human relationships would capitalize on these benefits, thereby improving animal welfare. Finally, this article proposes future research directions that may assist in disambiguating what constitutes successful bonding between dogs and the humans in their lives.
