Which scenario best indicates FRE?

Which scenario best indicates FRE?

• A. A dog with chronic GI signs that improves on a strict diet trial
• B. A dog with rapid improvement on antibiotics
• C. A dog with skin lesions only
• D. A dog with acute vomiting

Answer: (A)

Food-responsive enteropathy is diagnosed when chronic gastrointestinal signs improve after a strict diet trial, showing that dietary triggers are key to the dog’s GI inflammation. A sustained positive response to a hydrolyzed or novel/providing limited-ingredient diet indicates FRE because it demonstrates that removing offending dietary antigens can control the disease. The other scenarios point to different patterns: rapid improvement with antibiotics suggests antibiotic-responsive enteropathy or bacterial imbalance, not primary diet responsiveness; skin-only lesions don’t directly address GI tract disease; and acute vomiting reflects an acute issue rather than a chronic, diet-driven problem. Therefore, the scenario with chronic GI signs improving on a strict diet trial best indicates FRE.
