Effect of age and sex on plasma cortisol and dehydroepiandrosterone concentrations in the dog (Canis familiaris)
Limited data exist on age-related physiological variations in plasma concentrations of
cortisol and dehydroepiandrosterone (DHEA) in dogs, despite their potential role in the
pathophysiology of ageing. This study examined plasma cortisol and DHEA concentrations
and cortisol/DHEA ratio variations, according to age and sex in 311 dogs, aged from two
months to 16 years. Before adulthood, DHEA concentrations were higher in peri-pubertal
males. During adulthood, cortisol and DHEA were higher in males than females. Among …
