The relationship between humans and horses as companion animals encompasses the interactions, benefits, and management practices associated with keeping horses. These interactions can influence the behavior, welfare, and overall well-being of horses. The presence of other companion animals may affect the social dynamics within equine environments and can play a role in the management strategies employed by horse owners. This topic includes research that explores the behavioral responses of horses as companion animals to humans, the impact on stress levels, and the potential benefits or challenges of multi-species companionship. The page features peer-reviewed studies and scholarly articles that investigate the dynamics between horses and companion animals, providing insights into their cohabitation and its implications for equine management and welfare.
Walsh M, Fais S, Spugnini EP, Harguindey S, Abu Izneid T, Scacco L, Williams P, Allegrucci C, Rauch C, Omran Z.The treatment of cancer presents a clinical challenge both in human and veterinary medicine. Chemotherapy protocols require the use of toxic drugs that are not always specific, do not selectively target cancerous cells thus resulting in many side effects. A recent therapeutic approach takes advantage of the altered acidity of the tumour microenvironment by using proton pump inhibitors (PPIs) to block the hydrogen transport out of the cell. The alteration of the extracellular pH kills tumour cells, reverses drug resistance, and reduces cancer metastasis. Human clinical trials have prompted to c...
Raubenheimer D, Machovsky-Capuska GE, Gosby AK, Simpson S.We apply nutritional geometry, a framework for modelling the interactive effects of nutrients on animals, to help understand the role of modern environments in the obesity pandemic. Evidence suggests that humans regulate the intake of protein energy (PE) more strongly than non-protein energy (nPE), and consequently will over- and under-ingest nPE on diets with low or high PE, respectively. This pattern of macronutrient regulation has led to the protein leverage hypothesis, which proposes that the rise in obesity has been caused partly by a shift towards diets with reduced PE:nPE ratios relativ...
Saengtienchai A, Ikenaka Y, Nakayama SM, Mizukawa H, Kakehi M, Bortey-Sam N, Darwish WS, Tsubota T, Terasaki M, Poapolathep A, Ishizuka M.Interspecific differences in xenobiotic metabolism are a key to determining relative sensitivities of animals to xenobiotics. However, information on domesticated livestock, companion animals, and captive and free-ranging wildlife is incomplete. The present study evaluated interspecific differences in phase II conjugation using pyrene as a nondestructive biomarker of polycyclic aromatic hydrocarbon (PAH) exposure. Polycyclic aromatic hydrocarbons and their metabolites have carcinogenic and endocrine-disrupting effects in humans and wildlife and can have serious consequences. The authors collec...
Peli A, Scagliarini L, Calbucci S, Diegoli G.The increasing awareness of animal welfare issues among consumers and the general public in the European Union has brought about the adoption of laws for the protection of production animals throughout the various steps of the food chain, from breeding to slaughter. Considering that horses may be kept for a variety of reasons, including as companion animals and as farm animals, protective legislation in Europe applies to this species only partially. In consistency with the areas of competence of the European Union, it is the purpose of the activity (be it economic/commercial or neither) and no...
Müntener CR, Bruckner L, Kupper J, Althaus F, Caduff-Janosa P.167 adverse reactions of Swissmedic-authorized veterinary medicinal products were reported during the year 2011 (2010: 160). Species and drug classes remain comparable with previous years: most of the reactions occurred following the use of antiparasitic products (39 %), antiinfectives (20 %) or non-steroidal antiinflammatory drugs (11 %) in companion animals (85 dogs and 27 cats) followed by cattle/calves (37). We received 15 cases of adverse reactions following reconverted use, 8 of them in treated cats. Additionally the Swiss Toxicological Information Centre in Zürich processed 84 enquirie...
Santín M.Cryptosporidium spp. are frequent parasites of livestock and companion animals, raising questions about the clinical significance of such infections. Cryptosporidium infections have a wide spectrum of clinical signs that can vary from asymptomatic to serious infection to death. In neonatal ruminants, cryptosporidiosis is considered an important disease characterised by diarrhoea and mortality. In companion animals most infections are asymptomatic but severe clinical illness has also been reported in dogs, cats and horses. In birds, three main clinical forms of cryptosporidiosis are primarily s...
Egenvall A, Nødtvedt A, Roepstorff L, Bonnett B.In a world of limited resources, using existing databases in research is a potentially cost-effective way to increase knowledge, given that correct and meaningful results are gained.Nordic examples of the use of secondary small animal and equine databases include studies based on data from tumour registries, breeding registries, young horse quality contest results, competition data, insurance databases, clinic data, prescription data and hunting ability tests. In spite of this extensive use of secondary databases, integration between databases is less common. The aim of this presentation is to...
Loeffler A, Lloyd DH.This article reviews the literature on the epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) in dogs, cats and horses. Over the past 10 years, MRSA has emerged as an important pathogen in veterinary medicine, especially in countries with a high MRSA burden in human hospitals. During the same period, community-associated MRSA (CA-MRSA) infections in humans without apparent links to healthcare facilities have increased dramatically. Although animal infections occur outside human hospitals, significant epidemiological, clinical and genetic differences exist between CA-MRSA in hum...
Berny P, Caloni F, Croubels S, Sachana M, Vandenbroucke V, Davanzo F, Guitart R.This is the second in a series of three review articles on animal poisoning in Europe and focuses on cases in pet animals and horses in five European countries (Belgium, France, Greece, Italy and Spain) reported over the last decade. In the participating countries, dogs were the most commonly poisoned species, particularly younger animals. The majority of cases in companion animals resulted from exposure to insecticides, although rodenticides (especially anticoagulants and strychnine) posed a significant risk. In all five countries, horses and cats appeared to be more susceptible to plant toxi...
Scott Weese J.Antimicrobial resistance (AMR) is an emerging problem in companion animals, because of difficult-to-treat infections, possible pressure to use antimicrobials that are important in human medicine, and potential zoonotic transmission. The extent and importance of AMR in companion animals are poorly understood, in part because of limited surveillance; however, it is clear that resistance is problematic in many pathogens and commensals, including staphylococci, enterococci, Escherichia coli and Salmonella.
McNamara JP.Departments of animal sciences must be relevant to a society in which a small number of people can raise almost all the food animal products needed. The declining number of people involved in animal agriculture has decreased enrollment of students interested in food animals in many departments of animal science. However, several departments welcomed students from a diverse background and began research on animals other than food animals. In many states, the undergraduate enrollment is made up primarily of students interested only in companion animals. A benefit of this is that we have recruite...
Cawdell-Smith AJ, Pym RA, Verrall RG, Hohenhaus MA, Tribe A, Coleman GT, Bryden WL.Students in animal science and veterinary science at the University of Queensland (UQ) have similar introductory courses in animal handling in year 1 of their degree programs. Veterinary students take animal-handling instruction in farm and companion animals, whereas animal science students are instructed in handling farm animals, horses, and rodents. Veterinary students are introduced to rodents, and animal science students to dogs and cats, in subsequent years of the curriculum. Both cohorts receive additional training, with clinical emphasis for veterinary students in years 3, 4, and 5 of t...
Christensen JW, Malmkvist J, Nielsen BL, Keeling LJ.In fear-eliciting situations, horses tend to show flight reactions that can be dangerous for both horse and man. Finding appropriate methods for reducing fearfulness in horses has important practical implications. Objective: To investigate whether the presence of a calm companion horse influences fear reactions in naive subject horses. Objective: The presence of a habituated (calm) companion horse in a fear-eliciting situation can reduce fear reactions in naive subject horses, compared to subject horses with a nonhabituated companion (control). Methods: Minimally handled (n = 36), 2-year-old s...
Amann RP, Veeramachaneni DN.Cryptorchidism is failure of one or both testes to descend into the scrotum. Primary fault lies in the testis. We provide a unifying cross-species interpretation of testis descent and urge the use of precise terminology. After differentiation, a testis is relocated to the scrotum in three sequential phases: abdominal translocation, holding a testis near the internal inguinal ring as the abdominal cavity expands away, along with slight downward migration; transinguinal migration, moving a cauda epididymidis and testis through the abdominal wall; and inguinoscrotal migration, moving a s.c. cauda...
Isenbügel E.Over 45 million years of evolution the horse developed to a highly specialized animal in anatomy, physiology and behavior. No other animal had influenced the economic and cultural history of men to such extent. Hunting prey since the ice age, domesticated 4000 B.C. and used for thousands of years as unique animal all over the world has attained a new role today as partner in sport, as companion animal and even as cotherapeutic. The well known behavioral demands in use and keeping are still often not fulfilled.
Stang BV, Koller LD.To establish baseline information on neopterin concentrations in livestock, companion and laboratory animals and identify the factors that may influence these concentrations, blood samples were taken from normal dairy cattle, horses, llamas, dogs, cats and rats of varying ages and sexes. In addition, neopterin concentrations in normal, adult equines were compared with those found in racing Thoroughbreds. There were no differences due to sex, sexual maturity, pregnancy, castration, or age. For all ages and sexes combined, mean neopterin concentrations were significantly lower in llamas (2.27+/-...
Odendaal JS.A survey conducted in 1992, using a standardised, stratified sample was used to determine companion animal numbers in South Africa as a single geographical entity. The results indicated that there were 3.93 million dogs, 0.97 million cats, 0.98 million birds, 0.22 million other companion animals and 0.1 million horses in South African households. Thirty-seven per cent of households keeping companion animals, kept dogs; cats (13.4%); birds (4.8%); other companion animals (1.1%) and horses (2%). These results may provide information about possible markets in terms of numbers of species kept.
Wegner W.In 1893 a major component of veterinary practice derived from 4 million horses and from farm animals, whereas thousands of dogs were even slaughtered every year, especially in Saxony and Silesia. Nowadays companion animals figure as an element of ever growing importance for the practitioner. Teaching and research adapted themselves to this altered situation, research funding and professional politics not yet so completely. In former days veterinarians even presided the licensing committees for breeder animals--today the animal breeding act merely mentions them in connection with institutions o...
Squire KR, Fessler JF, Toombs JP, Van Sickle DC, Blevins WE.Femoral head ostectomy was performed in six horses, three ponies, and four cattle for treatment of fractures of the femoral capital physis, coxofemoral luxation, fractured acetabulum, or severe degenerative joint disease. The procedures were performed via a cranial approach that did not involve osteotomy of the greater trochanter. A dorsal approach for femoral head ostectomy via osteotomy of the greater trochanter was evaluated in three healthy adult ponies. Three animals (2 ponies, 1 calf) were euthanatized within a month and one horse was euthanatized at year 2 due to postoperative complicat...

Mowat FM, Iwabe S, Aguirre GD, Petersen-Jones SM.Companion animals, namely dogs, cats, and horses, can be affected with many forms of hereditary retinal disease. The number of such diseases characterized in the last decade has increased substantially, and nomenclature is nonstandardized, heterogenous, and confusing. We provide in this viewpoint article consensus guidelines for naming of companion animal hereditary retinal diseases, either prospectively or retrospectively. These consensus guidelines have been developed with the purpose of standardizing nomenclature. We provide examples for the iterative nomenclature process and a comprehensiv...

Koh RB, Harrison TM.Over the past years, the concept of pain management in veterinary medicine has evolved and led to the establishment of a new concept of multimodal approach to pain management, as the current standard of care. The use of multimodal analgesia combining pharmacologic and nonpharmacologic techniques not only helps optimize the quality and efficacy of analgesia but also may prevent the development of chronic or persistent pain. During the past decade, acupuncture has become more popular and evolved into one of the most used forms of integrative medicine interventions and nonpharmacologic therapeuti...

Müntener CR, Müntener C, Kupper J, Naegeli H, Gassner B.A total of 253 reports of adverse reactions to veterinary medicinal products were received during the year 2016 representing a decrease of 13% compared to the previous year (292 reports). The majority of the reports described reactions affecting companion animals (178 dogs and 32 cats) as well as cattle (17 reports) and horses (10 reports). Most of the reactions reported were linked to the use of antiparasitics (145 reports), hormone products (26 reports) and antiinfectives (10 reports). 32 reports were generated from consultations with Tox Info Suisse in Zürich and involved mainly the excess...
Boström A, Bergh A, Hyytiäinen H, Asplund K.Extracorporeal shockwave therapy (ECSWT) is increasingly used to treat different types of musculoskeletal conditions in sport and companion animals. To explore the scientific basis for the treatment, we conducted a systematic review of the literature on ECSWT used in horses, dogs, and cats. Methods: Relevant articles published in 1980-2020 were identified from three major databases. Each article was assessed for risk of bias. Results: The review identified 27 relevant articles on the effects of ECSWT in horses, nine in dogs, but none in cats. Typically, ECSWT involved one to three treatment se...
Rose WJ, Sargeant JM, Hanna WJB, Kelton D, Wolfe DM, Wisener LV.Acupuncture has become increasingly popular in veterinary medicine. Within the scientific literature there is debate regarding its efficacy. Due to the complex nature of acupuncture, a scoping review was undertaken to identify and categorize the evidence related to acupuncture in companion animals (dogs, cats, and horses). Our search identified 843 relevant citations. Narrative reviews represented the largest proportion of studies (43%). We identified 179 experimental studies and 175 case reports/case series that examined the efficacy of acupuncture. Dogs were the most common subjects in the e...
Hyytiäinen HK, Boström A, Asplund K, Bergh A.Electrotherapy modalities are currently used in the treatment of animals, but the evidence base supporting their use has not yet been systematically reviewed. Cochrane guidelines, as adapted by the Swedish Agency for Health Technology Assessment and Assessment of Social Services, were followed for this systematic review. A literature search regarding all currently known electrotherapy modalities applied to horses, dogs, and cats was conducted for the years 1980-2020 using three databases: CABI, PubMed, and Web of Science Core Collection. Of the 5385 references found, 41 articles were included ...

Gencoglu H, Orhan C, Sahin E, Sahin K.OA is quite common in companion animals, especially in large breed dogs and horses. Collagen, the most abundant protein of mammals, has specific connective tissue types for skin, bones, reticulate, basal lamina, bones, cell surfaces, while type II collagen (UC-II) forms the main structure of cartilage tissue. Even at the smaller dosages, UC-II has also been reported to be more effective than the glucosamine and chondroitin sulfate supplements, which are the supplements most frequently used in the market. In this review, we summarize the effects of UC-II on joint health and function in health a...

Schmitt S, Stephan R, Huebschke E, Schaefle D, Merz A, Johler S.Methicillin-resistant Staphylococcus aureus (MRSA) is a leading cause of severe infections in humans and animals worldwide. Studies elucidating the population structure, staphylococcal cassette chromosome mec types, resistance phenotypes, and virulence gene profiles of animal-associated MRSA are needed to understand spread and transmission. Objective: The objective of this study was to determine 1) clonal complexes and spa types, 2) resistance phenotypes, and 3) virulence/resistance gene profiles of MRSA isolated from animals in Switzerland. Methods: We analyzed 31 presumptive MRSA isolates co...
Petinaki E, Spiliopoulou I.Methicillin-resistant Staphylococcus aureus (MRSA) remains one of the most virulent human pathogens and has also recently been recognized as such in the veterinary settings. Companion animals, including dogs, cats, horses, small exotic animals, wildlife animals, and livestock, may constitute a reservoir for MRSA transmission to humans and vice versa. The evolution, emergence, and risk factors for MRSA transmission among colonized or infected animals are reviewed in the present paper, and infection control practices are discussed.

Scantamburlo G, Nofziger C, Paulmichl M, Vanoni S.Because of their importance as companion animals or as racehorses, horses can be treated with various drugs. Although it is known that drug withdrawal times can vary for each horse, pharmacogenetics for these animals has not been adequately studied and requires further development. Since is responsible for the metabolism of 25-30% of drugs in humans, including some used to treat horses, a study of the family in horses was conducted to define its genetic structure as well as its expression pattern in the liver. Unassigned: Genomic DNA extracted from venous blood and mRNA from fresh liver tiss...
Hermange T, Ruault B, Couroucé A.The aim of this study is to describe clinical data associated with acorn intoxication and to find variables associated with survival. Data from horses presented at CISCO-ONIRIS from 2011 to 2018 with a diagnosis of acorn intoxication were included. Diagnosis was based on the following: season, the presence of acorns in the environment, clinical and hemato-biochemical parameters suggestive of a digestive/renal disease, the co-morbidity of companion animals, and post-mortem findings. Statistical analysis was completed using Student's t-test for mean comparisons and a Chi-square test for group co...
Gao Y, Packeiser EM, Wendt S, Sekora A, Cavalleri JV, Pratscher B, Alammar M, Hühns M, Brenig B, Junghanss C, Nolte I, Murua Escobar H.Malignant melanomas (MMs) are the abnormal proliferation of melanocytes and are one of the lethal skin cancers in humans, equines, and canines. Accordingly, MMs in companion animals can serve as naturally occurring animal models, completing conventional cancer models. The common constitutive activation of the MAPK and PI3K pathways in MMs has been described in all three species. Targeting the related pathways is considered a potential option in comparative oncologic approaches. Herein, we present a cross-species comparative analysis exposing a set of ten melanoma cell lines (one human, three e...
Colbath AC, Goodrich L, Frye C, Dow S.Neurological diseases and injuries in veterinary patients (horses, dogs, and cats) are complex, and effective treatment options are limited. Neuronal loss, damage to nerve conduction pathways, and inflammation and scarring associated with spinal cord injury pose major challenges in managing many neurological diseases. Furthermore, most of these neuropathologies lack definitive pharmacological treatments, driving interest and research into novel interventions. Our objective is to provide a narrative review of the current literature surrounding cellular therapies including neuronal and glial ste...
Pratt-Phillips S.Obesity is an important health concern in horses, along with humans and companion animals. Adipose tissue is an inflammatory organ that alters the insulin-signaling cascade, ultimately causing insulin dysregulation and impaired glucose metabolism. These disruptions can increase the risk of metabolic disease and laminitis in horses and may also impact energy metabolism during exercise. A single bout of exercise, along with chronic exercise conditioning, increases insulin sensitivity and glucose disposal via both contraction- and insulin-mediated glucose uptake pathways. Regular exercise also in...
Attili AR, Nocera FP, Sisto M, Linardi M, Gigli F, Ngwa VN, Fiorito F, Cerracchio C, Meligrana MCT, Bonacucina E, Cuteri V, De Martino L.To evaluate the frequency of Acinetobacter spp., belonging to both Acinetobacter calcoaceticus-baumannii (ACB) and non-ACB complex, and their antibiotic resistance profiles in veterinary medicine, a three-year (2020-2022) retrospective study was carried out on sick companion animals. Epidemiological data from different clinical canine, feline, and equine samples, were acquired. For each strain, MALDI-TOF MS identification and susceptibility to a panel of 11 antibiotics, by Kirby-Bauer and E-test methods, were performed. Out of 628 bacteriological examinations, 2.5% resulted positive for strain...
