Thermography is used to detect abnormalities after radiation therapy (RT). However, in veterinary nursing, objective evaluation of the condition of dogs after RT using thermography has not been reported. We investigated the nasal irradiation temperature, behavioral changes, and post-irradiation pain scores in a dog receiving RT for intranasal tumors. The temperature of the nasal planum gradually increased after irradiation, reaching a significantly higher value at 120\u2013240 min. The highest temperature was 42.3 \u00b0C and the average temperature increased by 4.4 \u00b0C. Behavioral analysis pre- and post-RT did not vary significantly. Post-RT pain levels evaluated by the pain scale ranged from 0 to 1 throughout. No veterinary treatment was provided. In humans, increased skin temperature after radiation causes psychological stress, i.e., pain and discomfort, but no such behavioral changes were observed in this case. Given individual differences in stress-related behaviors, such as pain and discomfort, assessing a dog\u2019s painfulness using only subjective methods, such as appearance and behavioral evaluation, is limited. We used thermography to assess changes in conditions not detectable by routine monitoring alone. This method is non-invasive, objective, and indispensable for providing appropriate care.<\/jats:p>","DOI":"10.3390\/ani11092496","type":"journal-article","created":{"date-parts":[[2021,8,26]],"date-time":"2021-08-26T00:19:26Z","timestamp":1629937166000},"page":"2496","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Noninvasive Thermographic Photographing as an Assessment of the State of Discomfort in a Dog Receiving Radiation Therapy"],"prefix":"10.3390","volume":"11","author":[{"given":"Kaori","family":"Saeki","sequence":"first","affiliation":[{"name":"Faculty of Veterinary Medicine, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7160-992X","authenticated-orcid":false,"given":"Kenji","family":"Kutara","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4178-7551","authenticated-orcid":false,"given":"Eri","family":"Iwata","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Miyabe","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8961-6447","authenticated-orcid":false,"given":"Yuki","family":"Shimizu","sequence":"additional","affiliation":[{"name":"Veterinary Medical Teaching Hospital, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuko","family":"Wada","sequence":"additional","affiliation":[{"name":"Veterinary Medical Teaching Hospital, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akihiro","family":"Ohnishi","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7647-7484","authenticated-orcid":false,"given":"Akira","family":"Matsuda","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takako Shimokawa","family":"Miyama","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taketoshi","family":"Asanuma","sequence":"additional","affiliation":[{"name":"Faculty of Veterinary Medicine, Okayama University of Science, Imabari 794-8555, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102664","DOI":"10.1016\/j.jtherbio.2020.102664","article-title":"Advances in infrared thermography: Surgical aspects, vascular changes, and pain monitoring in veterinary medicine","volume":"92","year":"2020","journal-title":"J.
