Dog Population & Dog Sheltering Trends In The United States Of America, Andrew N. Rowan, Tamara Kartal

Demography and Statistics for Companion Animal Populations Collection

Dog management in the United States has evolved considerably over the last 40 years. This review analyzes available data from the last 30 to 40 years to identify national and local trends. In 1973, The Humane Society of the US (The HSUS) estimated that about 13.5 million animals (64 dogs and cats per 1000 people) were euthanized in the US (about 20% of the pet population) and about 25% of the dog population was still roaming the streets. Intake and euthanasia numbers (national and state level) declined rapidly in the 1970s due to a number of factors, including the implementation …

The Elephant (Head) In The Room: A Critical Look At Trophy Hunting, Chelsea Batavia, Michael Paul Nelson, Chris T. Darimont, Paul C. Paquet, William J. Ripple, Arian D. Wallach

Big-Game and Trophy Hunting Collection

Trophy hunting has occupied a prominent position in recent scholarly literature and popular media. In the scientific conservation literature, researchers are generally supportive of or sympathetic to its usage as a source of monetary support for conservation. Although authors at times acknowledge that trophy hunting faces strong opposition from many members of the public, often for unspecified reasons associated with ethics, neither the nature nor the implications of these ethical concerns have been substantively addressed. We identify the central act of wildlife “trophy” taking as a potential source of ethical discomfort and public opposition. We highlight that trophy hunting entails …

Using The Five Domains Model To Assess The Adverse Impacts Of Husbandry, Veterinary, And Equitation Interventions On Horse Welfare, Paul Mcgreevy, Jeannine Berger, Nic De Brauwere, Orla Doherty, Anna Harrison, Julie Fiedler, Claudia Jones, Sue Mcdonnell, Andrew Mclean, Lindsay Nakonechny, Christine Nichol, Liane Preshaw, Peter Thomson, Vicky Tzioumis, John Webster, Sarah Wolfensohn, James Yeates, Bidda Jones

Equine Husbandry and Welfare Collection

The aim of this study was to conduct a series of paper-based exercises in order to assess the negative (adverse) welfare impacts, if any, of common interventions on domestic horses across a

broad range of different contexts of equine care and training. An international panel (with professional expertise in psychology, equitation science, veterinary science, education, welfare, equestrian coaching, advocacy, and community engagement; n = 16) met over a four-day period to define and assess these interventions, using an adaptation of the domain-based assessment model. The interventions were considered within 14 contexts: C1Weaning; C2 Diet; C3 Housing; C4 Foundation training; C5 …

Bat Detective—Deep Learning Tools For Bat Acoustic Signal Detection, Oisin Mac Aodha, Rory Gibb, Kate E. Barlow, Michael Firman, Robin Freeman, Briana Harder, Libby Kinsey, Gary R. Mead, Stuart E. Newson, Ivan Pandourski, Stuart Parsons, Jon Russ, Abigel Szodoray-Paradi, Elena Tilova, Mark Girolami, Gabriel Brostow, Kate E. Jones

Bioacoustics Collection

Passive acoustic sensing has emerged as a powerful tool for quantifying anthropogenic impacts on biodiversity, especially for echolocating bat species. To better assess bat population trends there is a critical need for accurate, reliable, and open source tools that allow the detection and classification of bat calls in large collections of audio recordings. The majority of existing tools are commercial or have focused on the species classification task, neglecting the important problem of first localizing echolocation calls in audio which is particularly problematic in noisy recordings. We developed a convolutional neural network based open-source pipeline for detecting ultrasonic, full-spectrum, search-phase …

Longitudinal Trends In The Frequency Of Medium And Fast Race Winning Times In Australian Harness Racing: Relationships With Rules Moderating Whip Use, Bethany Wilson, Bidda Jones, Paul Mcgreevy

Sport and Working Animal Welfare Collection

The use of whips in racing is subject to current debate, not least because the prospect that fatigued horses cannot respond renders the practice futile and inhumane. The racing industries maintain whip use is a form of encouragement and that the rules of racing that govern whip use safeguard horse welfare. The current study examined longitudinal trends in the frequency of medium and fast race winning times in Australian harness racing between September 2007 and August 2016 to explore relationships with a series of changes that moderated whip use. The first change, introduced January 2010, moderated whip action so that …

Flogging Tired Horses: Who Wants Whipping And Who Would Walk Away If Whipping Horses Were Withheld?, Paul D. Mcgreevy, Mark D. Griffiths, Frank R. Ascione, Bethany Wilson

Sport and Working Animal Welfare Collection

Recent studies have cast doubt on the effectiveness of whipping horses during races and this has led to questions concerning its continuing justification. Furthermore, it has been argued that whipping tired horses in racing is the most televised form of violence to animals. The present study used de-identified data from a recent independent Australian poll (n = 1,533) to characterise the 26% of respondents (113 females and 271 males) who support the whipping of racehorses and the 10% of racing enthusiasts in the sample (44 females and 63 males) who would stop watching races and betting on them if whipping …

Justifiability And Animal Research In Health: Can Democratisation Help Resolve Difficulties?, Shaun Yon-Seng Khoo

Morality and Ethics of Animal Experimentation Collection

Current animal research ethics frameworks emphasise consequentialist ethics through cost-benefit or harm-benefit analysis. However, these ethical frameworks along with institutional animal ethics approval processes cannot satisfactorily decide when a given potential benefit is outweighed by costs to animals. The consequentialist calculus should, theoretically, provide for situations where research into a disease or disorder is no longer ethical, but this is difficult to determine objectively. Public support for animal research is also falling as demand for healthcare is rising. Democratisation of animal research could help resolve these tensions through facilitating ethical health consumerism or giving the public greater input into deciding …

Cognitive Dysfunction In Naturally Occurring Canine Idiopathic Epilepsy, Rowena M.A. Packer, Paul D. Mcgreevy, Hannah Salvin, Michael Valenzuela, Chloe M. Chaplin, Holger A. Volk

Neurology Collection

Globally, epilepsy is a common serious brain disorder. In addition to seizure activity, epilepsy is associated with cognitive impairments including static cognitive impairments present at onset, progressive seizure-induced impairments and co-morbid dementia. Epilepsy occurs naturally in domestic dogs but its impact on canine cognition has yet to be studied, despite canine cognitive dysfunction (CCD) recognised as a spontaneous model of dementia. Here we use data from a psychometrically validated tool, the canine cognitive dysfunction rating (CCDR) scale, to compare cognitive dysfunction in dogs diagnosed with idiopathic epilepsy (IE) with controls while accounting for age. An online cross-sectional study resulted in …

How Does Video Outreach Impact Pork Consumption?, Jo Anderson

Chickens Play To The Crowd, Cinzia Chiandetti

Animal Sentience

The time was ripe for Marino’s review of chickens’ cognitive capacities. The research community, apart from expressing gratitude for Marino’s work, should now use it to increase public awareness of chickens’ abilities. People’s views on many animals are ill-informed. Scientists need to communicate and engage with the public about the relevance and societal implications of their findings.

Post-Darwin Skepticism And Run-Of-The-Mill Suicide, John Hadley

Animal Sentience

Peña-Guzmán’s depiction of the opponent of animal suicide as a conservative is a straw man. It is possible to accept that animals are self-conscious and reflexive yet still reject the view that they have the mental wherewithal to commit run-of-the-mill suicide. That animal behaviour can be positioned on a continuum of self-destructive behaviour does not establish that animals can intentionally kill themselves.

An Adaptationist Perspective On Animal Suicide, Timothy P. Racine

Animal Sentience

Peña-Guzmán’s discussion of suicide in nonhuman animals has broad implications. In this commentary, I focus on the logical relation between suicide and intention. Proximate cause must be distinguished from ultimate function in explanations of suicide. I briefly discuss two adaptationist accounts of suicidal behavior.

Lessons From Chimpanzee Sign Language Studies, Mary Lee Jensvold

Animal Sentience

Claims are often made about behaviors being unique to humans; the evidence usually shows they are not. Sign language studies on chimpanzees may provide a useful model for comparative studies of suicide. A productive approach to comparative studies is to focus on observable behaviors rather than getting lost in the pitfalls of vague definitions and changing measures.

Animal Suicide: An Account Worth Giving?, Irina Mikhalevich

Animal Sentience

Peña-Guzmán (2017) argues that empirical evidence and evolutionary theory compel us to treat the phenomenon of suicide as continuous in the animal kingdom. He defends a “continuist” account in which suicide is a multiply-realizable phenomenon characterized by self-injurious and self-annihilative behaviors. This view is problematic for several reasons. First, it appears to mischaracterize the Darwinian view that mind is continuous in nature. Second, by focusing only on surface-level features of behavior, it groups causally and etiologically disparate phenomena under a single conceptual umbrella, thereby reducing the account’s explanatory power. Third, it obscures existing analyses of suicide in biomedical ethics and …

Can Nondolphins Commit Suicide?, David M. Peña-Guzmán

Animal Sentience

This Response addresses the scientific and philosophical criticisms of my 2017 target article “Can nonhuman animals commit suicide?” It defends my key claims and explores topics (such as animal judgment, animal theory of mind, and the evolution of suicide) that did not appear in the original article. It also points out areas in which further research is needed and concludes that we should be wary of accusations of “anthropomorphism” in debates about animal suicide.

Prodigal Pets: A History Of Animal Sheltering In America And The Origin Of The No Kill Movement, Susan K. Houser

eBooks

In 224 pages, this book traces the history of animal sheltering in the United States of America and its gradual transition from 1990 onwards into support for the "no-kill" goal in which less than 10% of animals entering shelters are euthanized. The includes extensive reporting identifying trends in animal shelter intakes and outcomes. All sources are carefully cited.

Encouraging Self-Reflection By Veterinary Clinicians: Ethics On The Clinic Floor, Sandra A. Corr, Clare Palmer, Peter Sandøe

Veterinary Medicine - Ethics

In this commentary, we agree that veterinarians often face troubling ethical decisions involving potential over- or undertreatment of their animal patients, the financial constraints of their clients, and, sometimes, the goals of the institutions that employ them. While we accept that a CEC may, in some contexts, be an appropriate structure in which to deal with such difficult decisions, we argue that this is not the only, or necessarily the best, approach. We suggest that the ethical problems facing veterinarians differ significantly in different countries; that many acute ethical issues typically arise before animals even arrive at the veterinary specialty …

Street Dog Management Program Monitoring And Evaluation Mussoorie, Uttarakhand, India October 2018, Tamara Kartal, Jamie Sneddon, Amit Chaudhari

Demographics and Populations

In 2016, Humane Society International India signed a Dog Population Management MoU with three Municipal Corporations in Uttarakhand (Dehradun, Nainital and Mussoorie). As part of the MoUs three individual dog population surveys were conducted in three cities in October 2016 to estimate the dog population and to establish a baseline against which progress can be measured.

In Mussoorie, due to infrastructure challenges the sterilization program was delayed until 2018 and the team started the sterilization program in September/October 2018. Due to the delay there are no effects of the program measurable yet. However, surveys continued and we have observed an …

The Impact Of An Integrated Program Of Return-To-Field And Targeted Trap-Neuter-Return On Feline Intake And Euthanasia At A Municipal Animal Shelter, Daniel Spehar, Peter Wolf

Management - TNR

Available evidence indicates that overall levels of feline intake and euthanasia at U.S. shelters have significantly declined in recent decades. Nevertheless, millions of cats, many of them free-roaming, continue to be admitted to shelters each year. In some locations, as many as 70% of cats, perhaps up to one million or more per year nationally, are euthanized. New approaches, including return-to-field (RTF) and targeted trap-neuter-return (TNR) appear to have transformative potential. The purpose of the present study was to examine changes in feline intake and euthanasia, as well as additional associated metrics, at a municipal animal shelter in Albuquerque, New …

A Case Study In Citizen Science: The Effectiveness Of A Trap-Neuter-Return Program In A Chicago Neighborhood, Daniel Spehar, Peter Wolf

Management - TNR

The use of trap-neuter-return (TNR) as a method of managing free-roaming cat populations has increased in the United States in recent decades. Historically, TNR has been conducted most often at a grassroots level, which has led to inconsistent data collection and assessment practices. Consequently, a paucity of analyzable data exists. An initiative is underway to standardize TNR program data collection and assessment. However, it could be some time before scientifically sound protocols are implemented on a broad scale. In the interim, sets of data collected by nascent citizen scientists offer valid opportunities to evaluate grassroots TNR programs. The purpose of …

The War On Animal Product Alternatives 2018, Lewis Bollard

Diet

The meat and dairy industries’ war on alternatives to their products is underway. In May, meat lobbyists got US House lawmakers to insert language into a spending bill directing the USDA to regulate all meat and poultry grown from cells. After the FDA held a surprisingly balanced forum on such “clean meat,” which it indicated its intention to regulate, the American Farm Bureau joined with all the major animal ag groups to lobby President Trump to put the USDA in charge. This may seem like an obscure jurisdictional dispute. But the stakes could be high: one FDA and USDA law …

Ultrasonic Deterrents Reduce Nuisance Cat (Felis Catus) Activity On Suburban Properties, Heather M. Crawford, Joseph B. Fontaine, Michael C. Calver

Predation and Wildlife

Urban environments are increasingly important for biodiversity conservation, but pet cats threaten wildlife therein, displaying nuisance behaviour such as hunting, fighting, fouling and urine spraying. In an attempt to empower landholders wishing to reduce cat incursions humanely, we tested the effectiveness of two ultrasonic cat deterrents (CatStop© and On-Guard Mega-Sonic Cat Repeller©).

After confirming in arena trials that cats detect and respond negatively to an ultrasonic device, we tested both deterrents in 18 suburban gardens in Perth, Western Australia. Camera monitoring at foci of cat activity (e.g. fish ponds, property entry/exit points) occurred for two weeks before (Period 1: device …

Tail Docking Of Canine Puppies: Reassessment Of The Tail’S Role In Communication, The Acute Pain Caused By Docking And Interpretation Of Behavioural Responses, David J. Mellor

General - Animal Welfare

Laws, regulations and professional standards increasingly aim to ban or restrict non-therapeutic tail docking in puppies. These constraints have usually been justified by reference to loss of tail participation in communication between dogs, the acute pain presumed to be caused during docking itself, subsequent experiences of chronic pain and heightened pain sensitivity, and the occurrence of other complications. These areas are reconsidered here. First, a scientifically robust examination of the dynamic functional foundations, sensory components and key features of body language that are integral to canine communication shows that the role of the tail has been greatly underestimated. More specifically, …
