We here propose a modification of the PRE scale with a 0\u201310 categorical scale for dogs, called the DeChant scale. A total of seventy-nine Labrador Retrievers were scored by video using the developed scale pre and post one of two different sprint exercise paradigms. The first exercise paradigm was 200 m in length and the second exercise paradigm was 1,200 m in length. PRE was reliably scored with an interclass correlation exceeding 0.8 for both exercise paradigms. The scale was further validated with moderate (<jats:italic>r<\/jats:italic> &amp;gt; 0.5) to strong correlations (<jats:italic>r<\/jats:italic> &amp;gt; 0.7) with core body temperature, rectal temperature, heart rate and respiration rate. The results suggest this PRE scale may be a useful, rapid and reliable visual measure of canine effort under exercise. Future research is needed for validation to other dog breeds and for use as a measure to predict detection performance or heat injury risk.<\/jats:p>","DOI":"10.3389\/fvets.2025.1528357","type":"journal-article","created":{"date-parts":[[2025,5,15]],"date-time":"2025-05-15T15:31:11Z","timestamp":1747323071000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["A scale to measure perceived respiratory effort in dogs: the DeChant scale"],"prefix":"10.3389","volume":"12","author":[{"given":"Mallory T.","family":"DeChant","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandra","family":"Moesta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nathaniel J.","family":"Hall","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,5,15]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"340","DOI":"10.17582\/journal.aavs\/2019\/7.5.340.345","article-title":"Impact of thermal stress on health signs, hormones levels, hematological and biochemical parameters of police dogs in Iraq","volume":"7","author":"Al-Shammari","year":"2019","journal-title":"Adv Anim Vet Sci"},{"key":"B2","doi-asserted-by":"publisher","first-page":"91","DOI":"10.3920\/CEP170039","article-title":"The effect of conditioning on exercise induced hyperthermia and post exercise cooling in dogs","volume":"14","author":"Baker","year":"2018","journal-title":"Comp Exercise Physio."},{"key":"B3","doi-asserted-by":"publisher","first-page":"673","DOI":"10.3390\/ani10040673","article-title":"Body temperature responses during phases of work in human remains detection dogs undergoing a simulated deployment","volume":"10","author":"Baker","year":"2020","journal-title":"Animals."},{"key":"B4","doi-asserted-by":"publisher","first-page":"174","DOI":"10.3389\/fvets.2017.00174","article-title":"Evaluation of three hydration strategies in detection dogs working in a hot environment","volume":"4","author":"Otto","year":"2017","journal-title":"Front Vet Sci."},{"key":"B5","first-page":"380","article-title":"Effort: perception of","author":"Marcora","year":"2010","journal-title":"Encyclopedia of Perception (1st Edn., vol. 1\u20132)"},{"key":"B6","first-page":"105","article-title":"Interindividual scaling and perception of muscular force","volume":"32","author":"Borg","year":"1961","journal-title":"K Fysiogr Saellsk Lund."},{"key":"B7","first-page":"377","article-title":"Psychophysical bases of perceived exertion","volume":"14","author":"Borg","year":"1962","journal-title":"Med Sci Sports Exerc."},{"key":"B8","doi-asserted-by":"publisher","first-page":"55","DOI":"10.5271\/sjweh.1815","article-title":"Psychophysical scaling with applications in physical work and the perception of exertion","volume":"16","author":"Borg","year":"1990","journal-title":"Scand J Work Environ Health."},{"key":"B9","doi-asserted-by":"publisher","first-page":"92","DOI":"10.2340\/1650197719702239298","volume":"2","author":"Borg","year":"1970","journal-title":"Perceived exertion as an indicator of somatic stress.
