Although colorimetry has been used to evaluate the skin erythema in allergic dogs, the native canine skin color remains unknown.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We measured the skin color in 101 healthy dogs using a calibrated optical system with a smartphone and a mobile dermatoscope DermLite DL1.

There was a difference of 3.9 in redness (<jats:italic>a*<\/jats:italic>) between canine and human skin, but this variation could be attributed to the similarly valued colorimetric error of the optical system. Nonetheless, the skin yellowness was significantly different for dogs and humans (respective median <jats:italic>b*<\/jats:italic> of 12.3 versus 16.6, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.01). This difference might be due to canids not being able to accumulate typically yellowish carotenoids. Furthermore, the native canine skin color did not exhibit a typical dependence between the coordinates of lightness (<jats:italic>L*<\/jats:italic>) and yellowness (<jats:italic>b*<\/jats:italic>), known as the individual typology angle, \u00b0ITA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We reported the first dataset of the native canine skin color in the CIELAB color space. We discovered a similarity in skin lightness and a difference in skin yellowness.

redness.<\/jats:p><\/jats:sec>","DOI":"10.1111\/srt.13130","type":"journal-article","created":{"date-parts":[[2022,1,22]],"date-time":"2022-01-22T10:01:50Z","timestamp":1642845710000},"page":"299-304","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation
