Nasal tumors in dogs are most frequently found in long-nosed breeds aged 10 to 15 years, especially among urban dogs. This case report describes a dog with recurrent bloody nasal discharge. Diagnostic tests, including laboratory analysis, CT, MRI, and histopathology, confirmed the diagnosis of nasal squamous cell carcinoma. The dog was treated with surgical resection and chemotherapy over 21 weeks. At the 21-week follow-up, nasal discharge had returned, prompting external carotid artery ligation, which reopened the nasopharynx.
