Plain-English summary
A study found that certain factors might increase the risk of solid oral tumors in dogs, which are types of cancer that can occur in the mouth. The research involved 80 dogs with oral tumors and 95 healthy dogs, and it looked at things like age, weight, diet, and exposure to barbecue smoke or professional dental cleaning. While these factors were linked to a higher risk of developing tumors like melanoma and squamous cell carcinoma, more research is needed to confirm these findings. If you're concerned about your dog's oral health, discussing these risk factors with your veterinarian could be helpful.

Abstract
INTRODUCTION: Solid oral tumors represent approximately 6% of malignant neoplasms in dogs, with melanoma, squamous cell carcinoma, and fibrosarcoma identified as the most prevalent types. This case-control study examined internal and external factors associated with their development. METHODS: Owners of 80 dogs with oral tumors and 95 healthy controls completed a structured epidemiological questionnaire. Univariate and multivariate analyses were performed. RESULTS: Significant associations were identified regarding age, weight, reproductive status, dietary habits, and environmental exposures, such as barbecue smoke and professional dental cleaning. DISCUSSION: These findings suggest potential risk factors, though the study's observational design requires cautious interpretation. Further investigation through prospective studies is warranted.
