A 3-month-old German shepherd puppy with a congenitally dilated oesophagus had radiographic, cinefluoroscopic, and oesophageal motility studies before a modified Heller operation was performed. Subsequent examination of the oesophagus revealed no ganglion cells, and the condition was considered to be identical with human achalasia. In dogs, this appears to be more common in the German shepherd ...

The study of the influence game behavior on mental state service dogs’ puppies German and Belgian (Malinois) shepherd breeds was conducted. experimental control groups included different ages - from 1-2 months to 3-6 months. were trained with use educational games for young dogs, did not have such training. As a result 6-month study, it proved that younger group showed best results in 2 4 tests...

Balkan Livestock Guardian Dogs (LGD) were bred to help protect sheep flocks in sparsely populated, remote mountainous areas the Balkans. The aim of this study was genomic characterization (107,403 autosomal SNPs) three LGD breeds from Balkans (Karst Shepherd, Sharplanina Dog, and Tornjak). Our analyses performed on 44 dogs representing breeds, as well 79 publicly available genotypes eight other...

Degenerative lumbosacral stenosis (DLSS) is a common condition amongst active large breed dogs with a complex aetiopathogenesis. Large-breed dogs, especially the German Shepherd (GSD), Retrievers and active or working dogs (Police, military or sporting dogs), are the most commonly affected by DLSS. Affected dogs are generally mature (mean age 5 1⁄2 years), and are predominantly heavier than 25 ...

BACKGROUND German shepherd dogs with inherited arrhythmias and sudden death appear to be a model for catecholamine-dependent ventricular tachycardias in human subjects. We tested the hypothesis that heterogeneity of left ventricular repolarization creates an arrhythmogenic substrate for pause-dependent ventricular tachycardia in these animals. METHODS AND RESULTS We used microelectrode techni...

There are many indications and much practical knowledge about the different tasks which various breeds of dogs are selected for. Correspondingly these different breeds are known to possess different physical and mental abilities. We hypothesized that commonly kept breeds will show differences in their problem solving ability in a detour task around a V-shaped fence, and also, that breed differe...
