Objective—To identify the most common cutaneous neoplasms in dogs and evaluate breed and age distributions for selected neoplasms.
Design—Retrospective epidemiological study.
Sample—Records available through the Veterinary Medical Database of dogs examined at veterinary teaching hospitals in North America between 1964 and 2002.
Procedures—Information on tumor type and patient breed and age was collected. Incidence and odds ratios with 95% confidence intervals were calculated.
Results—Records of 1,139,616 dogs were reviewed. Cutaneous neoplasms were diagnosed in 25,996 of these dogs; records for the remaining 1,113,620 dogs did not indicate that cutaneous neoplasms had been diagnosed, and these dogs were considered controls. The most frequent age range for dogs with cutaneous neoplasms was 10 to 15 years. Lipoma, adenoma, and mast cell tumor were the most common skin tumor types.
Conclusions and Clinical Relevance—Results supported previously reported data regarding cutaneous neoplasia in dogs but provided updated information on the most common skin tumors and on age and breed distributions.
