Age-dependent electrocardiographic and echocardiographic changes in German Shepherd dogs
Authors
Abstract:
By causing numerous changes in the cardiovascular system, ageing leads to a decreased threshold for clinical manifestation of heart disease. The aim of this study was to define the existence of cardiac structural and functional changes in healthy dogs of different age. Radiographic, electrocardiographic (ECG) and echocardiographic examinations of 20 clinically healthy German Shepherd dogs were performed in order to define the values of relevant parameters. Afterwards, the values of cardio examinations were compared between young and old dogs and statistically analyzed. The ECG recordings did not show the appearance of clinically significant arrhythmias, nor was their appearance significantly different between dogs of different age. Statistically significant differences in QRS duration (P

Echocardiographic indices in normal German shepherd dogs
Sixty clinically normal German shepherd dogs, 31 males and 29 females, ranging in age from 1 and 5 years and with a body weight ranging from 22 to 37.2 kg, were examined by the two-dimensional mode, M-mode, and Doppler echocardiography. In Doppler mode, the mitral valve flows were obtained, where the aim was to determine the velocity peaks and ratios of the E and A waves and the mitral E wave d...

The aims of this study were to define age-related histological changes in the articular cartilage of the stifle joint in non-chondrodystrophic dogs and to determine whether physical activity has a positive impact on preservation of cartilage structure during ageing. Twenty-eight German shepherd dogs were included in the study. These dogs had no evidence of joint inflammation as defined by clini...
full textHip dysplasia: coxafemoral abnormalities in neonatal German Shepherd dogs.
1. Hip dysplasia in German Shepherd Dogs, half of which could be expected to develop detectable hip dysplasia by 1 yr of age, was not observed at birth. This was based on the disection and gross examination of the pelves of eighty-seven neonatal pups. Minor ligamentous changes which may suggest beginning hip dysplasia were seen in three pelves from pups 30 days old. The round ligament seems to ...

In an epidemiological study based on insurance data we described a breed-specific pattern of diseases in German Shepherd dogs (GSD) and confirmed that this breed is predisposed to immune-related disorders. A prospective study was performed in order to further investigate immunological changes in the GSD using a large number of dogs, 30 bitches and their litters, from the same kennel under well ...
full textVisualization of Genome Diversity in German Shepherd Dogs.
A loss of genetic diversity may lead to increased disease risks in subpopulations of dogs. The canine breed structure has contributed to relatively small effective population size in many breeds and can limit the options for selective breeding strategies to maintain diversity. With the completion of the canine genome sequencing project, and the subsequent reduction in the cost of genotyping on ...
