The Influence of Dog Body Conditions on the Risk of Mastopathy

The article is devoted to the study of mastopathy risk assessment in overweight dogs. According to histopathological verification, among malignant neoplasms, ductal carcinoma is the most common (25%, 95% CI: 22–28%), benign tumors are fibroadenoma (20.6, 95% CI: 19–23%), dysplasia / hyperplasia is ductal ectasia (22.8%, 95% CI: 19–27%). According to the results of the statistical analysis, 30.7% (95% CI: 25–36%) of overweight bitches suffered from mastopathy, 46.5% (95% CI: 40–54%) from benign neoplasia, and 52.7% (95% CI: 47–59%) from malignant mammary neoplasms. It was established that over the past 3 years (from 2020 to 2022), the incidence of fibrocystic disease in bitches with excess body weight increased from 18.8% (95% CI: 16–22%) to 41.0% (95% CI: 38–44%) against the background of a decrease among patients with optimal body weight from 72.3% (95% CI: 69–76%) to 49.7% (95% CI: 45–55%). The risk of mastopathy correlates with the degree of overweight: with the exceeding of the optimal condition within 20%, the incidence was 20.8% (95% CI: 17–24%), for 30–50% it was 30.8% (95% CI: 23–38%), and for more than 50% it was 48.4% (95% CI: 41–56%). Compared to bitches with malignant mammary tumors, average body mass indices in dogs with benign neoplasia and mastopathy are significantly higher (p < .05 and p < .001, respectively). The number of patients with mastopathy increases with age; the maximum indicators were set in 91-year-old (35.8%, 95% CI: 29–42%) and older 11-year-old (32.6%, 95% CI: 26–39%) animals. German shepherd, Labrador retriever, boxer, poodle, and dachshund females are the most susceptible to fibrocystic disease (12.5%, 10.0%, 9.2%, 8.3%, and 8.3%, respectively), as well as mixed breeds (13.4%). The dynamic increase in the number of overweight bitches suffering from mastopathy confirms the importance of obesity in its pathogenesis.
