Obesity in dogs does not just affect body weight—it also predisposes them to serious metabolic disturbances. Tvarijonaviciute et al. (2012) investigated whether obese dogs develop metabolic dysfunction comparable to human metabolic syndrome (MS), a cluster of conditions linked to diabetes and cardiovascular disease.
In the study, 35 obese dogs were assessed before and after weight loss, with an average reduction of nearly 29% body weight. The researchers adapted human diagnostic criteria to define obesity-related metabolic dysfunction (ORMD) in dogs, including body condition, blood pressure, cholesterol, triglycerides, and glucose levels. Additional measurements included adiponectin, insulin, and inflammatory markers.
Results showed significant health improvements after weight loss. Systolic blood pressure, cholesterol, triglycerides, and fasting insulin all decreased, while plasma adiponectin increased, indicating restored metabolic balance. However, inflammation measured by C-reactive protein remained unchanged. Importantly, about 20% of obese dogs were identified with ORMD, characterized by low adiponectin (hypoadiponectinaemia) and high insulin (hyperinsulinaemia).
The findings underscore that canine obesity is more than excess fat—it can trigger systemic dysfunction similar to human metabolic syndrome. This highlights the importance of early detection, preventive weight management, and targeted interventions to reduce the risks of diabetes, cardiovascular issues, and other obesity-related diseases in dogs.
