Salivary alpha-amylase as a stress biomarker in diseased dogs

Abstract

Salivary alpha-amylase (sAA) is a stress biomarker in human diseases, but there are no reports of sAA measurements in diseased dogs. This study measured the sAA and serum alpha-amylase (AA) levels in 16 healthy dogs and 31 diseased dogs using a kinetic enzyme assay to assess the stress status. The sAA and serum AA levels were significantly higher in the diseased dogs than in healthy dogs (<i>p</i> < 0.05), but there was no correlation between the 2 groups (<i>r</i> = 0.251, <i>p</i> = 0.089). This suggests that sAA can be useful as a stress biomarker in diseased dogs.
