Demography and disorders of German Shepherd Dogs under primary veterinary care in the UK

BACKGROUND: The German Shepherd Dog (GSD) has been widely used for a variety of working roles. However, concerns for the health and welfare of the GSD have been widely aired and there is evidence that breed numbers are now in decline in the UK. Accurate demographic and disorder data could assist with breeding and clinical prioritisation. The VetCompass(TM) Programme collects clinical data on dogs under primary veterinary care in the UK. This study included all VetCompass(TM) dogs under veterinary care during 2013. Demographic, mortality and clinical diagnosis data on GSDs were extracted and reported. RESULTS: GSDs dropped from 3.5% of the annual birth cohort in 2005 to 2.2% in 2013. The median longevity of GSDs was 10.3 years (IQR 8.0–12.1, range 0.2–17.0). The most common causes of death were musculoskeletal disorder (16.3%) and inability to stand (14.9%). The most prevalent disorders recorded were otitis externa (n = 131, 7.89, 95% CI: 6.64–9.29), osteoarthritis (92, 5.54%, 95% CI: 4.49–6.75), diarrhoea (87, 5.24%, 95% CI: 4.22–6.42), overweight/obesity (86, 5.18%, 95% CI: 4.16–6.36) and aggression (79, 4.76%, 95% CI: 3.79–5.90). CONCLUSIONS: This study identified that GSDs have been reducing in numbers in the UK in recent years. The most frequent disorders in GSDs were otitis externa, osteoarthritis, diarrhoea, overweight/obesity and aggression, whilst the most common causes of death were musculoskeletal disorders and inability to stand. Aggression was more prevalent in males than in females. These results may assist veterinarians to offer evidence-based advice at a breed level and help to identify priorities for GSD health that can improve the breed’s health and welfare.
