Carter AJ, Hall EJ, Bradbury J, Beard S, Gilbert S, Barfield D, O'Neill DG. Post-exercise management of exertional hyperthermia in dogs participating in dog sport (canicross) events in the UK. J Therm Biol 2024; 121:103827. [PMID: 38518416 DOI: 10.1016/j.jtherbio.2024.103827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 02/27/2024] [Accepted: 02/27/2024] [Indexed: 03/24/2024]
Abstract
Exercise is a common trigger of heat-related illness (HRI) events in dogs, accounting for 74% of canine HRI cases treated under primary veterinary care in the United Kingdom. However, few empirical studies have evaluated the effectiveness of differing cooling methods for dogs with exertional hyperthermia or HRI. This study aimed to prospectively evaluate effects of ambient conditions and post-exercise management practices (cooling methods and vehicular confinement) on the post-exercise temperature change of dogs participating in UK canicross events. Canine temperature was recorded at three intervals post-exercise: as close as possible to 0- (immediately post-exercise), 5-, and 15-min post-exercise. Ambient conditions and post-exercise management were recorded for 115 cooling profiles from 52 dogs. In 28/115 (24.4%) profiles, the dog's temperature increased during the first 5-min post-exercise. Overall, 68/115 (59.1%) profiles included passive cooling (stood or walked outside), 35 (30.4%) active cooling (cold-water immersion or application of a cooling coat), and 12 (10.4%) involved no cooling and were immediately housed in vehicles. No dogs developed hypothermia during the study and no adverse effects were observed from any cooling method. In hyperthermic dogs, overall post-exercise body temperature change was significantly negatively associated (i.e. the dogs cooled more) with 0-min post-exercise body temperature (β = -0.93, p < 0.001), and not being housed in a vehicle (β = -0.43, p = 0.013). This study provides evidence cold-water immersion (in water at 0.1-15.0 °C) can be used to effectively and safely cool dogs with exertional hyperthermia. Progressive temperature increases in many dogs - even after exercise has terminated - supports the message to "cool first, transport second" when managing dogs with HRI. When transporting dogs post-exercise or with HRI even after active cooling, care should be taken to cool the vehicle before entry and promote air movement around the dog during transport to facilitate ongoing cooling and prevent worsening of hyperthermia during travel.

Abstract
Introduction Dogs are increasingly being employed for conservation purposes worldwide. In Africa, they work in challenging environments with unique health risks which have not been investigated until now. Methods To understand the health challenges faced by the dogs, semi-structured interviews were conducted with participants from 14 organisations that used working dogs in their conservation programmes. The data was qualitatively analysed by thematic analysis. Results Five themes were generated. Three affective themes influenced how participants responded to the challenges associated with having a successful conservation dog programme. A strong handler-dog attachment, proficient handler training, and the acknowledgement of the challenging environment were pivotal to maintaining dog health. Two themes related to the difficulties in managing these programmes and how veterinary support interacts with the management choices being made. Discussion To have healthy conservation dogs, current and future programmes should focus on fostering the handler-dog relationship and provide continuous handler training. The management of conservation dogs' health should adopt an evidence-based approach. Future research should focus on areas where the evidence base is lacking, particularly in the areas of prevention and treatment of African canine trypanosomiasis. Programmes should develop a good working relationship with a veterinarian that has access to evidence-based veterinary medical information.

Abstract
The popularity of synthetic cannabinoids puts police sniffer dogs at risk of accidental introduction of such substances into the body. The extreme efficacy and potency of many new synthetic cannabinoids are associated with a high risk of serious poisonings and even deaths. The paper presents the toxicological findings in an intoxication of a police dog, in which a new synthetic cannabinoid ADB-BUTINACA was detected and quantified in postmortem materials. The screening analyses were performed by liquid chromatography with tandem mass spectrometry (LC-MS-MS) and liquid chromatography--quadrupole/time-of-flight mass spectrometry (LC-QTOF-MS). LC-MS-MS was also used for quantitative analyses, while LC-QTOF-MS for metabolite identification. Due to unusual matrices, the standard addition method was used for the quantitative determination of ADB-BUTINACA. The determined concentrations of ADB-BUTINACA in blood, lung, stomach, liver and kidney were 8.1 ng/mL, 6.4 ng/g, 1.5 ng/g, 1.8 ng/g and 0.4 ng/g, respectively. Apart from ADB-BUTINACA, the monohydroxylated metabolites and the dihydrodiol metabolite were detected and identified in all analyzed materials, and moreover the product of N-debutylation was found in blood and liver. The described case presents the identification and quantitation of a new synthetic cannabinoid ADB-BUTINACA in postmortem dog specimens. Although the cause of death was acute gastric dilatation, it cannot be ruled out that this process was the result of synthetic cannabinoid inhalation. Due to dogs' sensitivity to cannabinoids, ADB-BUTINACA poisoning cannot be excluded either. The described case suggests that ADB-BUTINACA elicits serious adverse effects in dogs. The article also indicates the dangers to which police dogs coming into contact with extremely potent drugs may be exposed.

Abstract
The ongoing coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused a large global outbreak. The reports of domestic animals' infection with SARS-CoV-2 raise concerns about the virus's longer-lasting spread, the establishment of a new host reservoir, or even the evolution of a new virus, as seen with COVID-19. In this review, we focus on the susceptibility of domestic animals, especially companion animals, towards SARS-CoV-2 in light of existing studies of natural infection, experimental infection, and serological surveys. Susceptibility of domestic and companion animals to SARS-CoV-2 infection.

Abstract
Simple Summary Dog walking is important for maintaining the good health and welfare of pet dogs. Environmental factors such as weather conditions have been previously identified as potential barriers to dog walking but, so far, focus has been on the impact this has on the human. With more seasonal weather variation predicted due to climate change, it is unclear if weather also impacts on the willingness of dogs to undertake exercise and thus the overall activity levels of pet dogs. An online survey recruited 3153 respondents to outline the impact of summer and winter weather conditions on daily canine activity levels. Owners reported their dogs were more impacted by cold (48.2% less likely to exercise their dog in the cold) and ice (64.0% less likely), than rain (25.3% less likely). In hot weather, 81.7% of owners reported reduced exercise duration and 87.0% reported less vigorous exercise by their dogs. As extreme weather events are likely to become more commonplace, it is likely this will negatively impact dog activity levels. Climate change mitigation strategies must therefore include considerations for dogs, if our canine companions are to retain their positions of service and companionship. Abstract Climate change is leading to more instances of seasonal weather variation. Studies have explored the impact of adverse winter weather on dog walking, but the impact on the dog’s overall activity levels have not been previously considered. This study explored dog owner perceptions of the effects of both summer and winter weather on their dog’s activity levels. An international online survey recruited 3153 respondents between May and December 2018, to explore the impact of summer and winter weather conditions on baseline activity levels. Owners reported their dogs were more impacted by cold (48.2% less likely to exercise their dog in the cold) and ice (64.0% less likely), than rain (25.3% were less likely). In hot weather, over 80% of owners reported reduced exercise duration and vigour for their dogs. Carrying water or walking near water to facilitate activity in the summer was the most popular mitigation strategy (90.8%). Participation in dog sports appeared to reduce the impact of winter weather on canine activity and increase owner awareness of cooling strategies to facilitate summer activity. Strategies to promote safe activity participation are needed to maintain canine activity levels amidst rising global temperatures, including better understanding of cooling strategies for exercising dogs.

Abstract
The surgical cricothyrotomy (CTT) has been recommended for emergency front of neck airway access (eFONA) during a cannot intubate, cannot oxygenate scenario for military working dogs (MWD) and civilian law enforcement working dogs (operational K9s). In prehospital and austere environments, combat medics and emergency medical service providers are expected to administer emergency medical care to working dogs and may only have emergency airway kits designed for humans at their disposal. The objective of this article is to provide a detailed description of the application of such devices in cadaver dogs and highlight potential alterations to manufacturer guidelines required for successful tube placement. The kits evaluated included the Portex® PCK, Melker universal cricothyrotomy kit and H&H® emergency cricothyrotomy kit. A novel technique for awake cricothyrotomy in the dog is also described, which can also be considered for in-hospital use, together with the open surgical method described for the H&H® kit. To the authors' knowledge, this is the first publication documenting and providing instruction on the application of commercial cricothyrotomy kits in dogs.

Abstract
OBJECTIVE To analyze the epidemiology of veterinary care in canine trauma patients prior to presentation to a Veterinary Trauma Center (VTC). DESIGN Retrospective observational cross-sectional study. METHODS Retrospective descriptive analysis from 22,998 canine case records from the Veterinary Trauma Registry from September 2013 through April 2018. Analysis was focused on the type of injury, care provider, and care provided prior presentation to a VTC (pre-VTC care). A log-likelihood ratio test was used to test for association of outcome and pre-VTC care. Mann-Whitney U tests were used to compare modified Glasgow Coma Scale and Animal Trauma Triage (ATT) scores between pre-VTC and non-pre-VTC care groups. MEASUREMENTS AND MAIN RESULTS Pre-VTC care was provided in 5636 out of 22,998 dogs (24.5%) by veterinarians (81%), owners (19.6%), and first responders (0.03%). The most common nonveterinary interventions included wound care and bandaging in 42% and 39% of the patients, respectively. Mortality was higher in the pre-VTC care group (8.7% vs 7.5%); dogs receiving pre-VTC care were 1.5 times (95% confidence interval [CI], 1.15-1.88) more likely to die and 1.2 times (95% CI, 1.07-1.37) more likely to be euthanized. The ATT scores were significantly higher in dogs receiving pre-VTC care (mean = 2.53 vs 1.78; p < 0.0001). CONCLUSION Our data demonstrate that the majority of more severely injured dogs receiving pre-VTC care obtained care by a veterinarian. Dogs receiving pre-VTC care possessed a greater mortality rate but also a greater ATT score; therefore, mortality rate is more likely related to severity of trauma rather than reception of pre-VTC care. We propose that these data should prompt further research and education about prehospital care in veterinary medicine.

Abstract
Hemorrhage is a significant cause of death among military working dogs and in civilian canine trauma. While research specifically aimed at canine trauma is limited, many principles from human trauma resuscitation apply. Trauma with significant hemorrhage results in shock and inadequate oxygen delivery to tissues. This leads to aberrations in cellular metabolism, including anaerobic metabolism, decreased energy production, acidosis, cell swelling, and eventual cell death. Considering blood and endothelium as a single organ system, blood failure is a syndrome of endotheliopathy, coagulopathy, and platelet dysfunction. In severe cases following injury, blood failure develops and is induced by inadequate oxygen delivery in the presence of hemorrhage, tissue injury, and acute stress from trauma. Severe hemorrhagic shock is best treated with hemostatic resuscitation, wherein blood products are used to restore effective circulating volume and increase oxygen delivery to tissues without exacerbating blood failure. The principles of hemostatic resuscitation have been demonstrated in severely injured people and the authors propose an algorithm for applying this to canine patients. The use of plasma and whole blood to resuscitate severely injured canines while minimizing the use of crystalloids and colloids could prove instrumental in improving both mortality and morbidity. More work is needed to understand the canine patient that would benefit from hemostatic resuscitation, as well as to determine the optimal resuscitation strategy for these patients.

Abstract
INTRODUCTION U.S. Army Veterinary Corps provides highly skilled and adaptive veterinary professionals to protect and improve the health of people and animals while enhancing readiness throughout the DOD. Army veterinarians must be trained and credentialed for critical tasks within the animal health and food protection missions across all components. The Veterinary Metrics Division in the U.S. Army Public Health Center's Veterinary Services and Public Health Sanitation Directorate is responsible for tracking readiness metrics of Army veterinarians and maintains a robust online Readiness Metrics Platform. Readiness targets were developed based on trends in readiness platform data, input of senior veterinary subject matter experts, and feedback from the field. To date, no data have been published describing the cases presented to DOD-owned Veterinary Treatment Facilities (VTFs). Without capturing and codifying the types of cases that present to the VTF and comparing to cases typically encountered during deployments, it is difficult to determine whether the VTF serves as an adequate readiness platform. In this study, we compare a representative random sample of non-wellness VTF patient encounters in garrison to cases reported from two different combat zones to determine if the VTF is a suitable clinical readiness platform. MATERIALS AND METHODS Multiple data sources, including pre-existing published data and new data extracted from multiple sources, were used. The Iraq 2009-2010 dataset includes data collected from a Medical Detachment, Veterinary Service Support (MDVSS) deployed to Iraq from January 5, 2009 through August 23, 2010. The Iraq 2003-2007 dataset originated from a retrospective cross-sectional survey that included database and medical record abstraction. The Afghanistan 2014-2015 dataset includes data collected from the MDVSS deployed to Afghanistan from June 2014 to March 2015. Working dog veterinary encounter data were manually extracted from monthly and daily clinical reports. Data for the Garrison 2016-2018 dataset were extracted from the Remote Online Veterinary Record. A random representative sample of government-owned animal (GOA) and privately owned animal (POA) encounters seen across all DOD-owned VTFs from June 2016 to May 2018 were selected. RESULTS We found that animals present to the VTF for a wide variety of illnesses. Overall, the top 10 encounter categories (90.3%) align with 84.2%, 92.4%, and 85.9% of all the encounter types seen in the three combat zone datasets. Comparing these datasets identifies potential gaps in readiness training relying solely on the VTF, especially in the areas of traumatic and combat-related injuries. CONCLUSIONS Ultimately, the success of the DOD Veterinary Services Animal Health mission depends on both the competence and confidence of the individual Army veterinarian. As the MHS transitions and DOD Veterinary Services continues to transform emphasizing readiness through a public health and prevention-based Army medicine approach, Army veterinarians must strike a delicate balance to continue to provide comprehensive health care to GOAs and POAs in the VTFs. Leaders at all levels must recognize the roles VTFs play in overall public health readiness and disease prevention through the proper appropriation and allocation of resources while fostering the development, confidence, and competence of Army veterinarians training within these readiness platforms.

J Vet Emerg Crit Care (San Antonio) 2021; 31:498-507. [PMID: 34014602 DOI: 10.1111/vec.13064] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2019] [Revised: 01/15/2020] [Accepted: 01/20/2020] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To compare the prevalence of types of trauma, mechanisms of injury, and outcomes among military working dogs (MWDs), operational canines (OpK9s), and civilian dogs (CDs) that sustained traumatic injury. DESIGN Retrospective descriptive analysis. ANIMALS One hundred and ninety-three cases of MWD trauma, 26,099 cases of CD trauma, 35 cases of OpK9 trauma. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Medical records of MWDs that incurred trauma while deployed to the Middle East were identified, and information was extracted from these records. The resultant database was compared to CD and OpK9s in the American College of Veterinary Emergency and Critical Care (ACVECC) Veterinary Committee on Trauma registry. All 3 groups showed similar trends with regard to type of trauma: penetrating injuries occurred most frequently, followed by blunt injuries for CDs and OpK9s. An equal proportion of blunt and blunt and penetrating traumas were observed in MWDs. Only MWDs sustained trauma from explosions, which accounted for 22.3% of injuries in this group. Animal bite/scratch/quilling and motor vehicle accidents (MVAs) were significantly more prevalent among CDs than MWDs (P < 0.01), whereas injuries from gunshot wounds (GSW) or a knife/sharp object were more common among MWDs compared to CDs (P < 0.01). No statistical differences in survival were observed between CDs and MWDs after excluding civilian dogs euthanized due to financial limitations. CONCLUSIONS MWDs, OpK9s, and CDs experience differences in injury type, mechanism, and outcome. Regardless, MWDs and CDs have good prognosis for survival to discharge after trauma.

Abstract
Emerging infectious diseases present great risks to public health. The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing coronavirus disease 2019 (COVID-19), has become an urgent public health issue of global concern. It is speculated that the virus first emerged through a zoonotic spillover. Basic research studies have suggested that bats are likely the ancestral reservoir host. Nonetheless, the evolutionary history and host susceptibility of SARS-CoV-2 remains unclear as a multitude of animals has been proposed as potential intermediate or dead-end hosts. SARS-CoV-2 has been isolated from domestic animals, both companion and livestock, as well as in captive wildlife that were in close contact with human COVID-19 cases. Currently, domestic mink is the only known animal that is susceptible to a natural infection, develop severe illness, and can also transmit SARS-CoV-2 to other minks and humans. To improve foundational knowledge of SARS-CoV-2, we are conducting a synthesis review of its host diversity and transmission pathways. To mitigate this COVID-19 pandemic, we strongly advocate for a systems-oriented scientific approach that comprehensively evaluates the transmission of SARS-CoV-2 at the human and animal interface.

Front Vet Sci 2020; 7:292. [PMID: 32582777 PMCID: PMC7283960 DOI: 10.3389/fvets.2020.00292] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Accepted: 04/29/2020] [Indexed: 11/13/2022] Open
Abstract
The objective of this study was to evaluate 4 pre-exercise hydration strategies (oral water, chicken-flavored water, chicken-flavored oral electrolyte solution, and subcutaneous electrolyte solution) in working dogs conducting rigorous tracking operations in hot and arid conditions. In a randomized cross-over field study, 7 Border Patrol Search, Trauma, and Rescue (BORSTAR) Unit dogs working/training out of Fort Bliss in El Paso, Texas were randomly assigned to one of 4 different hydration strategy treatments each day for 4 days of study participation. Dogs were provided hydration treatment prior to running 2 separate one-mile tracks and were offered water while tracking. Body weight, blood, and urine were collected at the beginning of the study day and at the completion of each track. Core body temperatures were recorded using internal temperature sensing capsules. The impact of hydration strategy on change in weight, peak temperature, and serum chemical, hematological, and urinary parameters were analyzed using the COIN procedure in Ra. Compared to the other 3 hydration strategies, dogs receiving chicken-flavored water had higher blood creatine kinase values at the end of the second track (p = 0.0361). Otherwise, hydration strategy had minimal effects on blood or urine parameters. Total fluid intake was lower with water only compared to the other three hydration strategies. Dogs developed elevated core body temperatures (median 41°C; 106°F) without signs of heat exhaustion or heat stroke. Alternate hydration strategies increased total fluid intake compared to water alone; however, chicken-flavored water resulted in increased markers of muscle injury suggesting electrolyte-enriched strategies may have an advantage as a hydration strategy. Additionally, electrolyte-enriched fluids before exercise may help these dogs maintain lower peak temperatures.

Prevalence of Bartonella sp. in United States military working dogs with infectious endocarditis: a retrospective case-control study. J Vet Cardiol 2019; 27:1-9. [PMID: 31830708 DOI: 10.1016/j.jvc.2019.11.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2018] [Revised: 11/08/2019] [Accepted: 11/10/2019] [Indexed: 11/20/2022]
Abstract
OBJECTIVES Bartonella infection has been associated with endocarditis in humans, dogs, cats and cattle. In order to evaluate the importance of this pathogen as a possible source of endocarditis in United States military working dogs (MWDs), we performed a retrospective case-control study on 26 dogs with histological diagnosis of culture negative endocarditis (n = 18), endomyocarditis (n = 5) or endocardiosis (n = 3) and 28 control dogs without any histological cardiac lesions. METHODS DNA was extracted from paraffin embedded cardiac valves and tissues from case and control dogs and submitted to PCR testing with primers targeting the Bartonella gltA gene. PCR-RFLP using four restriction endonucleases and partial sequencing was then performed to determine the Bartonella species involved. RESULTS Nineteen (73%) cases were PCR positive for Bartonella, including B. henselae (8 dogs), B. vinsonii subsp. berkhoffii (6 dogs), B. washoensis (2 dogs) and B. elizabethae (1 dog). Only one control dog was weakly PCR positive for Bartonella. Based on the type of histological diagnosis, 13 (72.2%) dogs with endocarditis, 3 (60%) dogs with endomyocarditis and all 3 dogs with endocardiosis were Bartonella PCR positive. CONCLUSIONS Bartonella sp. Infections were correlated with cardiopathies in US military working dogs. Systemic use of insecticides against ectoparasites and regular testing of MWDs for Bartonella infection seem highly appropriate to prevent such life-threatening exposures.
