Since then, only a few cases have been documented. Twenty-two adult dogs owned by private individuals were evaluated. All dogs exhibited thick crusts forming plaques and marked scaling on the face\u2014particularly around the lips, nasal bridge, and eyelids\u2014as well as on the paw pads, dorsal digits, abdomen, and dorsum. Pruritus ranged from moderate to severe, and all dogs showed varying degrees of lethargy and reduced activity. Each dog was fed a low-quality commercial diet. A presumptive diagnosis of dermatosis associated with poor-quality food was made. Skin biopsies from nine dogs revealed similar histopathologic changes, characterized by epidermal hyperplasia, severe parakeratotic hyperkeratosis with spongiosis, and exocytosis of lymphocytes and neutrophils. The skin lesions resolved within 15\u201330 days after switching to a high-quality diet. This case series highlights that dermatosis associated with low-quality food should remain in the differential diagnosis for dogs presenting with symmetric crusted and scaly lesions on the face, mucocutaneous junctions, and paws, particularly when nutritional deficiencies are suspected.<\/jats:p>","DOI":"10.3390\/vetsci13010106","type":"journal-article","created":{"date-parts":[[2026,1,21]],"date-time":"2026-01-21T11:11:17Z","timestamp":1768993877000},"page":"106","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dermatosis Associated with Feeding Low-Quality Food (Generic Food Dermatosis): A Case Series"],"prefix":"10.3390","volume":"13","author":[{"given":"Alejandro","family":"Blanco","sequence":"first","affiliation":[{"name":"Servicio de Dermatolog\u00eda del Hospital Escuela, Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, Ciudad Aut\u00f3noma de Buenos Aires C1427CWO, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melisa","family":"L\u00f3pez","sequence":"additional","affiliation":[{"name":"Servicio de Dermatolog\u00eda del Hospital Escuela, Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, Ciudad Aut\u00f3noma de Buenos Aires C1427CWO, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Kantor","sequence":"additional","affiliation":[{"name":"Independent Researcher, Ciudad Aut\u00f3noma de Buenos Aires C1427CWO, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adriana","family":"Duchene","sequence":"additional","affiliation":[{"name":"Servicio de Patolog\u00eda del Hospital Escuela, Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, Ciudad Aut\u00f3noma de Buenos Aires C1427CWO, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1537-0074","authenticated-orcid":false,"given":"Llu\u00eds","family":"Ferrer","sequence":"additional","affiliation":[{"name":"Departament de Medicina i Cirurgia Animals, Facultat de Veterin\u00e0ria, Universitat Aut\u00f2noma de Barcelona, Bellaterra, 08193 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Jiang, N., Quan, T., Li, R., Chen, Y., and Gao, T.
