High fat, high risk? Evaluating the strength of evidence linking dietary fat and pancreatitis in dogs.

Dietary fat restriction may not prevent pancreatitis in all dogs; evidence remains insufficient.

Pancreatitis remains the most frequently diagnosed exocrine pancreatic disorder in dogs, yet its etiology is incompletely understood. This narrative review challenges the long-standing clinical recommendation to restrict dietary fat in affected dogs, which was based on early studies with significant methodological limitations including experimental models, small sample sizes, inconsistent diagnostic criteria, inability to isolate fat-specific effects, and use of outdated diet formulations. The authors note clinical observations of dogs relapsing or maintaining elevated pancreatic lipase despite strict low- or ultralow-fat diet adherence, suggesting dietary fat restriction may not be the primary prevention strategy for all pancreatitis cases. Recent literature examining the dietary fat-pancreatitis relationship has generally failed to establish a consistent or straightforward association between dietary fat content and disease onset. This review systematizes current knowledge, identifies critical research gaps, and recommends priorities for future investigations to improve understanding of this clinically significant condition in veterinary medicine.
