One hundred Tumours in 100 Dogs: A histopathological study

Abstract

The rising incidence of tumours in canine populations poses significant challenges for veterinary health and clinical management. This one-year retrospective study evaluated the occurrence and histopathological spectrum of 100 canine tumours submitted to a private diagnostic laboratory in Gujarat. Of these, epithelial tumours were most prevalent (76%), followed by round cell (14%) and mesenchymal tumours (10%). Mammary gland tumours were the most common neoplasms, with melanoma, mast cell tumours, and lipoma also frequently identified. Epithelial malignancies predominated across cases. The findings highlight the importance of early detection, routine screening of cutaneous and mammary masses, and improved awareness for timely diagnosis and management of canine neoplasia. These results also emphasize the influence of regional factors, referral patterns, and owner awareness on tumour profiles. Strengthening diagnostic practices and preventive strategies may help reduce the overall tumour burden in dogs.
