- Background Concentrations of cardiac troponin I (cTnI) and C-reactive protein (CRP) might be associated with cardiac remodeling in dogs with myxomatous mitral valve disease (MMVD). Age- and sex-dependent variations in cTnI concentration have been described. Objective To investigate whether plasma concentrations of cTnI and CRP are associated with severity of MMVD, and investigate potential associations of dog characteristics on cTnI and CRP concentrations. Animals Eighty-one client-owned dogs with MMVD of varying severity. Methods Dogs were prospectively recruited for the study. Dogs were classified according to severity of MMVD. Plasma cTnI was analyzed by a high sensitivity cTnI assay with a lower limit of detection of 0.001 ng/mL, and plasma CRP was analyzed by a canine-specific CRP ELISA. Results Higher cTnI concentrations were detected in dogs with moderate (0.014 [interquartile range 0.008-0.029] ng/mL, P = .0011) and severe (0.043 [0.031-0.087] ng/mL, P < .0001) MMVD, compared with healthy dogs (0.001 [0.001-0.004] ng/mL). Dogs with severe MMVD also had higher cTnI concentrations than dogs with mild (0.003 [0.001-0.024] ng/mL, P < .0001) and moderate (P = .0019) MMVD. There were significant associations of age, CRP, heart rate, and left ventricular end-diastolic diameter, on cTnI concentration C-reactive protein did not differ among severity groups, but was significantly associated with cTnI, breed, and systolic blood pressure on CRP concentration. Conclusions and Clinical Importance Analysis of cTnI concentration has potential to increase knowledge of overall cardiac remodeling in dogs with MMVD. However, effect of age on cTnI needs consideration when assessing cTnI.

- The objective of this prospective study was to determine the prevalence of gait abnormalities in a cohort of Swedish pugs by using an owner-based questionnaire targeting signs of gait abnormality and video footage showing the dog's gait. This study also evaluated associated conditions of abnormal gait, including other health disorders prevalent in the breed. Five hundred and fifty (550) pugs registered in the Swedish Kennel Club, of one, five and eight years of age, in 2015 and 2016, were included in the study. Gait abnormalities were reported in 30.7 per cent of the responses. In the majority of cases, the character of the described gait indicated a neurological cause for the gait abnormality. An association was observed between abnormal gait and age, with gait abnormalities being significantly more common in older pugs (P=0.004). An association was also found between abnormal gait and dyspnoea, with dyspnoea being significantly more common in pugs with gait abnormalities (P<0.0001). This study demonstrated that the prevalence of gait abnormalities was high in the Swedish pug breed and increased with age. Future studies on the mechanisms behind these gait abnormalities are warranted.

- Congenital vertebral malformations (CVMs) are common in brachycephalic dogs such as the pug, and are often considered incidental findings. However, specific CVMs have been suggested to be associated with neurological deficits in pugs. The objective of this study was to investigate the clinical importance of CVMs in the pug by comparing computed tomography studies of the thoracolumbar spine from pugs without neurological deficits with those from pugs with a confirmed T3-L3 spinal cord lesion and neurological deficits consistent with a chronic T3-L3 myelopathy. A total of 57 pugs were recruited into the study from Sweden (n=33), United Kingdom (n=21) and Norway (n = 3); 30 with neurological deficits and 27 without. Focal T3-L3 pathology was confirmed in all pugs with neurological deficits by magnetic resonance imaging (n = 29) and/or pathology (n = 15). Computed tomography studies of the thoracolumbar spine from pugs with and without neurological deficits were compared to investigate possible associations between presentation of neurological deficits consistent with chronic T3-L3 pathology and signalment variables, presence of CVMs and type of CVMs. Congenital vertebral malformations were as common in pugs with, as in pugs without, neurological deficits. Regardless of neurological status, the majority of pugs (96%) presented with one or more CVM. An association between presence, or type of CVM in the T1-L3 vertebral column, and neurological deficits consistent with T3-L3 pathology could not be confirmed.

- Methods: Records and radiographs from 24 cavalier King Charles spaniels with mitral regurgitation were used. Vertebral heart scale (24 dogs), and left atrial dimension and left ventricular end diastolic and end systolic diameters (18 dogs) and their rate of increase were measured at intervals over years to the onset of congestive heart failure. They were plotted against time to onset of congestive heart failure.Results: Dimensions and rates of change of all parameters were highest at onset of congestive heart failure, the difference between observed and chance outcome being highly significant using a two-tailed chi-square test (P < 0 center dot 001).Clinical significance: The left heart chambers increase in size rapidly only in the last year before the onset of congestive heart failure. Increasing left ventricular end systolic dimension is suggestive of myocardial failure before the onset of congestive heart failure. Rate of increase of heart dimensions may be a useful indicator of impending congestive heart failure.

- Introduction: Although challenging, predicting outcomes in dogs with myxomatous mitral valve disease (MMVD) is of importance to owners and veterinar-ians. Our aim was to compare the prognostic value of selected one-, two-, and three-dimensional and Doppler echocardiographic methods to predict cardiac-re-lated and all-cause mortality in MMVD dogs. We hypothesize that three-dimensional methods would better predict prognosis than one-and two-dimensional methods.Animals: One-hundred thirty-eight privately-owned dogs with MMVD. Materials and methods: Cox proportional Hazard analyses and Kaplan-Meier curves were used to investigate the predictive value of 14 variables; left atrial (LA) volume indexed to body weight (BW) measured by real-time three-dimensional echocardio-graphy (RT3DE) and calculated using Simpson's modified method of discs (SMOD) and the area-length method; LA diameter in short-axis and long-axis to aortic in short-axis ratio, effective regurgitant orifice area indexed to body surface area measured in RT3DE en face view and calculated using four-chamber (4Ch) and two-chamber views alone or in combination; percentage increase in left ventricular end-diastolic and systolic internal diameters; fractional shortening; E wave velo -city; regurgitant jet area/LA area. Results: All 14 variables were significantly predictive of cardiac-related mortality, and 11 were predictive of all-cause mortality. The prognosis was best predicted by LA volume/BW estimated by SMOD or RT3DE, consistently showing the highest pre-dictive value in all analyses.Conclusions: Left atrial volume calculated by SMOD showed a similar predictive va-lue compared to RT3DE. Performing SMOD from apical 4Ch images should be consid-ered an alternative to RT3DE for echocardiographic examinations where prognostication of disease outcome is sought. 2021 Elsevier B.V.

- Diabetes mellitus is a serious health problem in both dogs and humans. Certain dog breeds show high prevalence of the disease, whereas other breeds are at low risk. Fructosamine and glycated haemoglobin (HbA1c) are two major biomarkers of glycaemia, where serum concentrations reflect glucose turnover over the past few weeks to months. In this study, we searched for genetic factors influencing variation in serum fructosamine concentration in healthy dogs using data from nine dog breeds. Considering all breeds together, we did not find any genome-wide significant associations to fructosamine serum concentration. However, by performing breed-specific analyses we revealed an association on chromosome 3 (rho(corrected) approximate to 1:68 x 10(-6)) in Belgian shepherd dogs of the Malinois subtype. The associated region and its close neighbourhood harbours interesting candidate genes such as LETM1 and GAPDH that are important in glucose metabolism and have previously been implicated in the aetiology of diabetes mellitus. To further explore the genetics of this breed specificity, we screened the genome for reduced heterozygosity stretches private to the Belgian shepherd breed. This revealed a region with reduced heterozygosity that shows a statistically significant interaction (rho = 0.025) with the association region on chromosome 3. This region also harbours some interesting candidate genes and regulatory regions but the exact mechanisms underlying the interaction are still unknown. Nevertheless, this finding provides a plausible explanation for breed-specific genetic effects for complex traits in dogs. Shepherd breeds are at low risk of developing diabetes mellitus. The findings in Belgian shepherds could be connected to a protective mechanism against the disease. Further insight into the regulation of glucose metabolism could improve diagnostic and therapeutic methods for diabetes mellitus.

- Cardiovascular disease in humans and dogs is associated with mildly increased circulating concentrations of C-reactive protein (CRP). Few studies have evaluated associations between circulating CRP and canine myxomatous mitral valve disease (MMVD) and the results reported have been divergent. The aim of this study was to investigate whether serum concentrations of CRP, determined using a novel automated canine-specific high -sensitivity CRP assay (Gentian hsCRP), were associated with severity of MMVD and selected clinical variables in dogs. The study included 188 client-owned dogs with different severities of MMVD. Dogs were classified based on ACVIM consensus statement guidelines (group A, n = 58; group BI, n = 56; group B2, n = 38; group C, n = 36). Data were analysed using descriptive statistics and multiple regression analysis.Dogs with congestive heart failure (CHF; group C) had significantly higher CRP concentrations (median, 2.65 mg/L; quartile 1 -quartile 3, 1.09-5.09) compared to dogs in groups A (median, 0.97 mg/L; quartile 1-quartile 3, <0.50-1.97; P = 0.001), B1 (median, 0.78 mg/L; quartile 1 -quartile 3, <0.50-1.73, P < 0.0001) and B2 (median, 0.60 mg/L; quartile 1-quartile 3, <0.50-1.23; P <0.0001). Other variables reflecting disease severity, including left atrial to aortic root ratio (P= 0.0002, adjusted r(2) = 0.07) and left ventricular end diastolic diameter normalised for bodyweight (P = 0.0005, adjusted r(2) = 0.06), were positively associated with CRP concentration, but the association disappeared if dogs with CHF were excluded from analysis. In conclusion, slightly higher CRP concentrations were found in dogs with CHF whereas severity of asymptomatic MMVD showed no association with CRP concentrations. (C) 2016 Elsevier Ltd.
