Separation-related behaviours (SRBs) in dogs (Canis familiaris) often indicate poor welfare. Understanding SRB risk factors can aid prevention strategies. We investigated whether early-life experiences and dog-owner interactions affect SRB development. Using a longitudinal study, we conducted exploratory analyses of associations between potential risk factors and SRB occurrence in six month old puppies (n = 145). Dogs were less likely to develop SRBs if owners reported that, at ≤ 16 weeks old, puppies were restricted to crates/rooms overnight and had ≥ 9 h of sleep per night. Puppies with poor house-training at ≤ 16 weeks were more likely to show SRBs, as were those trained using dog treats or novel kibble versus other rewards. Puppies whose owners used more punishment/aversive techniques when responding to ‘bad’ behaviour had increased odds of SRBs at six months versus other puppies. Puppies whose owners reported ‘fussing’ over their dogs at six months in response to ‘bad’ behaviour upon their return, versus those whose owners responded in other ways, were six times more likely to display SRBs. Other factors, including dog breed, sex and source, showed no significant association with SRB occurrence. Thus, SRB development might be prevented by enabling sleep for ≥ 9 h in early life, providing enclosed space overnight, refraining from aversive training of puppies generally, and avoiding fussing over puppies in response to unwanted behaviour following separation. These recommendations derive from correlational longitudinal study results, so analysis of interventional data is required for confirmation regarding effective prevention strategies.

In 2020, the Kuujjuaq Dog Project (KDP) was operationalized in the Northern Village of Kuujjuaq (Québec, Canada) to mitigate issues at the human–dog interface. Differing from previous interventions in its EcoHealth approach, it provided veterinary services, educational components (school workshops and Facebook posts) and strengthened local dog control measures. In 2022, an implementation evaluation assessed its quality of its delivery, differentiation, adaptations and the community’s responsiveness. The study followed key principles of the One Health approach and a mixed-methods design, combining a survey of 74 participants and individual interviews with 10 key stakeholders and 25 other community members. Analysis confirmed the relevance of the KDP, highlighting its innovative nature compared to previous dog-related interventions in northern Québec. Awareness of and exposure to the KDP’s components varied considerably between veterinary services (89%), Facebook posts (55%) and school workshops (27%). Global exposure to both the veterinary services and educational components was lower among Inuit, men and non-dog owners (not statistically significant). Barriers and facilitators to implementation included long-term engagement of stakeholders and building meaningful partnerships with local stakeholders. Beside supporting the future evolution of the KDP, this study fills knowledge gaps on how to successfully implement integrated, participatory interventions in northern Indigenous communities.

Jesus' response to the Syrophoenician woman in Mark 7.27 is sometimes seen as sexist, racist, or abusive. The force of his response depends in part on the diminutive form κυναριον, which is often dismissed as a faded diminutive that lacks true force. But a statistical, semantic, and contextual analysis of the word indicates that it does, in fact, have diminutive force in Mark 7:27. Because of this, the pejorative force found in direct insults employing the word ‘dog’ is lacking in Jesus' response. In addition to failing to recognise the diminutive force of κυναριον, interpreters sometimes assume a social context in which Jews routinely referred to Gentiles as dogs. Finally, the analogy that Jesus makes is often read allegorically, assuming that ‘children’ and ‘dogs’ have direct counterparts in ‘Jews’ and ‘Gentiles’. These assumptions are found to be dubious. The point of Jesus' analogy is about the proper order of events: children eat before the puppies; Jews receive the benefits of his ministry before Gentiles. The Syrophoenician woman outwits Jesus by arguing that the puppies may eat simultaneously with the children. The interpretive upshot is that Jesus' saying is unlikely to be misogynistic or abusive, but simply asserts Jewish priority, a priority that admits of exceptions and change.

Multiple studies have demonstrated that European colonization of the Americas led to the death of nearly all North American dog mitochondrial lineages and replacement with European ones sometime between AD 1492 and the present day. Historical records indicate that colonists imported dogs from Europe to North America, where they became objects of interest and exchange as early as the seventeenth century. However, it is not clear whether the earliest archaeological dogs recovered from colonial contexts were of European, Indigenous, or mixed descent. To clarify the ancestry of dogs from the Jamestown Colony, Virginia, we sequenced ancient mitochondrial DNA from six archaeological dogs from the period 1609–1617. Our analysis shows that the Jamestown dogs have maternal lineages most closely associated with those of ancient Indigenous dogs of North America. Furthermore, these maternal lineages cluster with dogs from Late Woodland, Hopewell, and Virginia Algonquian archaeological sites. Our recovery of Indigenous dog lineages from a European colonial site suggests a complex social history of dogs at the interface of Indigenous and European populations during the early colonial period.

Ixodid ticks are obligate blood-feeding arthropods and important vectors of pathogens. In Mallorca, almost no data on the tick fauna are available. Herein, we investigated ticks and tick-borne pathogens in ticks collected from dogs, a cat and humans in Mallorca as result of a citizen science project. A total of 91 ticks were received from German tourists and residents in Mallorca. Ticks were collected from March to October 2023 from dogs, cat and humans, morphologically and genetically identified and tested for pathogens by PCRs. Six tick species could be identified: Ixodes ricinus (n = 2), Ixodes ventalloi (n = 1), Hyalomma lusitanicum (n = 7), Hyalomma marginatum (n = 1), Rhipicephalus sanguineus s.l. (n = 71) and Rhipicephalus pusillus (n = 9). Rhipicephalus sanguineus s.l. adults were collected from dogs and four females from a cat and the 16S rDNA sequences identified it as Rh. sanguineus s.s. Hyalomma lusitanicum was collected from 1 human, 1 dog and 5 specimens were collected from the ground in the community of Santanyi, together with one H. marginatum male. This is the first report of Hyalomma marginatum in Mallorca. Both I. ricinus were collected from humans and I. ventalloi female was collected from a dog. All ticks tested negative for Anaplasma phagocytophilum, Coxiella spp., Francisella spp., and piroplasms. In 32/71 (45%) specimens of Rh. sanguineus s.s., Rickettsia spp. could be detected and in 18/32 (56.2%) sequenced tick DNAs R. massiliae was identified. Ixodes ventalloi female and both I. ricinus tested positive in the screening PCR, but the sequencing for the identification of the Rickettsia sp. failed.

Some regulations do not only reduce human deaths, injuries, and illnesses; they also protect nonhuman animals. Regulatory Impact Analyses, required by prevailing executive orders, usually do not disclose or explore benefits or costs with respect to nonhuman animals, even when those benefits or costs are significant. This is an inexcusable gap. If a regulation prevents dogs, horses, or cats from being killed or hurt, the benefits should be specified and quantified. This proposition holds even if those benefits are in some sense incidental to the main goal of the regulation. At the same time, turning the relevant benefits into monetary equivalents raises serious challenges, akin to those raised by the valuation of statistical children.

This article examines the dog-like aspects and associations of two marine monsters of Graeco-Roman antiquity: Scylla and the κῆτος. Both harbour recognizably canine features in their depictions in ancient art, as well as being referenced as dogs or possessing dog-like attributes in ancient texts. The article argues that such distinctly canine elements are related to, and probably an extension of, the conceptualization of certain marine animals, most prominently sharks, as ‘sea dogs’. Accordingly, we should understand these two sea monsters and the sea dogs as being interrelated in the ancient imagination. Such a canine resonance to certain sea creatures offers a valuable insight into the Graeco-Roman imagination of the marine element as being the abode of creatures reminiscent of terrestrial dogs.

Excavations at the vicarage yard (prästgården) at the famous Late Iron Age magnate centre of Gamla Uppsala, Sweden, have yielded six Viking Age (c. ad 750–1100) boat burials, several containing the remains of domestic dogs. The present study is an osteological examination of the remains of three of these dogs, one each from three boat graves, with a primary goal of morphological reconstruction and a secondary focus on identifying sex, age, and pathology. Two dogs were large, slender sight hounds, while the third was somewhat smaller and of indeterminate type. The preference for sight hounds in high-status graves is consistent with previous results from the contemporaneous nearby boat cemeteries of Vendel and Valsgärde, adding weight to the hypothesis of a shared funerary culture between these sites in the Late Iron Age.

Efficient adoption is an important aim of animal shelters, but it is not possible for all animals including those with serious behavioural problems. We used institutional ethnography to explore the everyday work of frontline shelter staff in a large animal sheltering and protection organisation and to examine how their work is organised by standardised institutional procedures. Shelter staff routinely conduct behavioural evaluations of dogs and review intake documents, in part to plan care for animals and inform potential adopters about animal characteristics as well as protect volunteers and community members from human-directed aggression. Staff were challenged and felt pressure, however, to find time to work with animals identified as having behavioural problems because much of their work is directed toward other goals such as facilitating efficient adoption for the majority and anticipating future demands for kennel space. This work is organised by management approaches that broadly aim to maintain a manageable shelter animal population based on available resources, decrease the length of time animals spend in shelters and house animals based on individual needs. However, this organisation limits the ability of staff to work closely with long-stay animals whose behavioural problems require modification and management. This also creates stress for staff who care for these animals and are emotionally invested in them. Further inquiry and improvements might involve supporting the work of behavioural modification and management where it is needed and expanding fostering programmes for animals with special needs.

Canine soil-transmitted helminths (STHs) cause important zoonoses in the tropics, with varying degrees of intensity of infection in humans and dogs. This study aimed to investigate the prevalence and associated risk factors for STHs in community dogs residing in Grenada, West Indies. In May 2021, 232 canine fecal samples were examined for zoonotic helminths by microscopy (following flotation), and genomic DNA from a subset of 211 of these samples were subjected to multiplex qPCR for the detection and specific identification of hookworms, Toxocara spp. and Strongyloides. Microscopic examination revealed that 46.5% (108/232, 95% CI 40–52.9), 9% (21/232, 95% CI 5.35–12.7) and 5.2% (12/232, 95% CI 2.3–8) of the samples contained eggs of Ancylostoma spp., Toxocara spp. and Trichuris vulpis, respectively. Multiplex qPCR revealed that, 42.2% (89/211, 95% CI 35.5–48.8) were positive for at least 1 zoonotic parasite. Of these, 40.8% (86/211, 95% CI 34.1–47.3) of samples tested positive for Ancylostoma spp., 36% (76/211, 95% CI 29.5–42.9) were positive for A. caninum, 13.3% (28/211, 95% CI 9–18.6) for A. ceylanicum, 5.7% for T. canis (12/211, 95% CI 2.97–8.81) and 1% (2/211, 95% CI 0–2.26) for Strongyloides spp. (identified as S. stercoralis and S. papillosus by conventional PCR-based Sanger sequencing). Using a multiple logistic regression model, a low body score and free-roaming behaviour were significant predictors of test-positivity for these parasitic nematodes in dogs (P < 0.05). Further studies of zoonotic STHs in humans should help elucidate the public health relevance of these parasites in Grenada.

Ancylostoma caninum is the most common nematode parasite of dogs in the United States. The present study aimed to describe the molecular epidemiology of A. caninum isolates from the central and eastern states of the United States using the partial mitochondrial cytochrome oxidase (cox1) gene and to compare them with those reported globally. We isolated eggs from faecal samples of dogs and characterized each isolate based on cox1 sequences. A total of 60 samples originating from Kansas, Iowa, New York, Florida and Massachusetts were included. 25 haplotypes were identified in the United States dataset with high haplotype diversity (0.904). Sequence data were compared to sequences from other world regions available in GenBank. Global haplotype analysis demonstrated 35 haplotypes with a haplotype diversity of 0.931. Phylogenetic and network analysis provide evidence for the existence of moderate geographical structuring of A. caninum haplotypes. Our results provide an updated summary of A. caninum haplotypes and data for neutral genetic markers with utility for tracking hookworm populations. Sequences have been deposited in GenBank (ON980650–ON980674). Further studies of isolates from other regions are essential to understand the genetic diversity of this parasite.

Dogs have played a vital and varied role in the social history of early China. Whether used as a source of food, a hunting-aid, or a sacrificial victim, dogs were intimately connected with human life and death. The placement and significance of dismembered and slaughtered dogs in human tombs have been a source of scholarly interest across the twentieth and twenty-first centuries. However, less attention has been paid to sources which present us with a spectrum of concerns surrounding the treatment of dogs after their death. Should they be consumed, discarded, or buried? Which dogs were deserving of burial, and how were such burials viewed by human commentators? By analysing textual, archaeological, and material sources, this article explores the changing conceptualisation of dogs in life and in death through the medium of the tomb, showing how the transition from tomb-keeper to tomb-occupant reflects an increasingly anthropomorphic view of canine potential and moral fibre by the early medieval period.

Animal rescue shelters provide temporary housing for thousands of stray and abandoned dogs every year. Many of these animals fail to find new homes and are forced to spend long periods of time in kennels. This study examined the influence of the length of time spent in a rescue shelter (<1 month, 2-12 months, 1-5 years, >5 years) on the behaviour of 97 dogs. The dogs ‘ position in their kennels (front, back), their activity (moving, standing, sitting, resting, sleeping), and their vocalisation (barking, quiet, other) were recorded over a 4 h period at 10 min intervals. The dogs’ behaviour was significantly related to the length of time the animals had spent in the rescue shelter. Dogs housed in the shelter for over five years spent more of their time at the back of their kennels, more time resting, and less time barking than dogs housed in the shelter for shorter periods of time. The age of the dog could not account for the significant results found, suggesting that environmental factors were responsible for the change in the dogs’ behaviour. The findings suggest that lengthy periods of time spent in a captive environment may encourage dogs to behave in a manner that is generally considered unattractive by potential buyers. This may decrease the chances of such dogs being adopted, resulting in longer periods of time spent in the kennel environment and the possible development of further undesirable behaviours.

This study explored the influence of five types of visual stimulation on the behaviour of 50 dogs housed in a rescue shelter. These conditions were: one control condition (no visual stimulation) and four experimental conditions (blank television screen, and moving televised images of conspecifics, interspecifics [ie unfamiliar animal species] and humans). The dogs were exposed to each condition for 4 h per day for five days, with an intervening period of two days between conditions. The dogs' behaviour was recorded on days 1, 3 and 5 during each condition. Dogs spent relatively little of the total observation time looking at the television monitors (10.8%). They spent significantly more of their time looking at the moving images of conspecifics, interspecifics and humans than at the blank screen, although their interest in all experimental conditions declined over time. Dogs spent more time at the front of their enclosures during all of the experimental conditions than during the control condition. Images of conspecifics were more likely to attract the dogs to the front of their kennels than the blank screen. The conspecific and human conditions of visual stimulation attracted slightly more attention from the dogs than the interspecific condition, although not significantly. All of the experimental conditions encouraged significantly less vocalisation and movement than the control condition. Overall, the findings suggest that the behaviour of kennelled dogs is influenced by visual stimulation in the form of television programmes. Such animals, however, may not benefit from this type of enrichment to the same degree as species with more well-developed visual systems. The addition of other types of enrichment strategy for dogs housed in rescue shelters is advocated.

This study explored the influence of five toys (squeaky ball, non-squeaky ball, Nylabone chew, tug rope and Boomer ball) on the behaviour of 32 adult dogs housed in a rescue shelter. The dogs were exposed to each toy separately for six days, with an intervening period of one day between toys. The dogs' location in their kennels (front or back), activity (moving, standing, sitting or resting) and vocalisation (barking, quiet or other) were recorded over 4 h at 10 min intervals on Days 1, 3 and 5 during a control condition (no toy present) and during five experimental (toy) conditions. Whether or not the dogs were observed playing with the toys during the experimental conditions was also recorded. The dogs spent relatively little (<8%) of the overall observation time playing with the toys. The toys elicited varying degrees of interest, with dogs showing a preference for the Nylabone chew over the other toys. The dogs' interest in the toys waned over time, but the speed of habituation to the Nylabone chew was slower than to any of the other toys. The dogs' activity was significantly related to toy condition: dogs spent more time moving and less time standing during the Nylabone chew, squeaky ball and non-squeaky ball conditions than during any of the other conditions. It is suggested that the welfare of kennelled dogs may be slightly enhanced by the addition of suitable toys to their kennels. It is advised, however, that toys are rotated to encourage exploration and reduce habituation. The provision of other forms of environmental enrichment is also recommended.
