A retrospective study on 462 cases of tumor conditions in dogs was carried out in Pathology laboratory, School of Veterinary Medicine, St George’s University, Grenada, West Indies for a period of ten years, from 2001 to 2010. Out of these 462 tumors, 242 and 220 tumors were recorded from males and females of varying age groups respectively. Among all these tumor conditions, the occurrence of haemangiosarcoma was found to be highest (13%) followed by mammary gland tumors (10.8%), transmissible venereal tumors (7.6%), cutaneous hemangioma (7.4%), cutaneous histiocytoma (6.3%), lymphoma and papilloma (5.0% each), mast cell tumor (4.5%), lipoma and squamous cell carcinoma (3.5% each), melanocytoma (3.2%), fibrosarcoma, hemangiopericytoma and melanoma (2.6% each), fibroma (2.2%) and others including basal cell tumor and chondrosarcoma (1.5% each), seminoma (1.3%), plasmacytoma (1.1%), perianal gland adenoma (0.9%) and adenocarcinoma (0.6%), hepatocellular carcinoma (0.6%), pancreatic adenocarcinoma (0.6%), pheochromocytoma (0.4%), sertoli cell tumor (0.2%), etc. Age–wise, the highest tumor occurence (28.1%) was in the >8–12 year age group, followed by 25.8% in >5–8 year, 19.7% in >12 year, 14.1% in >3–5 year and 10.2% in >1–3 year age groups. Mixed breed dogs showed highest tumor incidence (62.6%) followed by German shepherd (6.5%), Labrador Retriever (5.6%), Rottweiler (4.3%), Doberman Pinscher (3.2%), Pompek (3.0%) and Pitbull (2.2%).
