In dogs with Addison's disease, GI signs are present in approximately what proportion?

• A. More than 70% of affected dogs show GI signs.
• B. Less than 30% show GI signs.
• C. GI signs are present in all cases.
• D. GI signs are never present.

Answer: (A)

Gastrointestinal signs are a common presenting feature of canine Addison's disease because cortisol and aldosterone deficiencies disrupt gut function and fluid-electrolyte balance, leading to vomiting, diarrhea, and inappetence. This occurs in the majority of affected dogs, typically cited as more than 70%. That level of frequency fits the pattern seen in clinical experience, making it the best choice. It isn’t universal—some dogs may present mainly with weakness or electrolyte-driven collapse, and GI signs can be absent in a minority—so statements claiming universal presence or rarity aren’t accurate.
