Which of the following is least likely a clinical sign of allergies?

• A. Face rubbing
• B. Ear problems
• C. Loss of appetite
• D. Skin rashes

Answer: (C)

Allergic reactions in animals most often present with itchiness and dermatologic or ear involvement. The strongest clues are behaviors driven by pruritus, such as face rubbing, and inflammation that leads to dermatitis with visible skin changes or rashes. Ear problems frequently arise from allergic inflammation and secondary infections, which explains why ear issues are common in allergic patients. Loss of appetite, while it can occur with many illnesses, is not a typical primary sign of allergies—it points more toward gastrointestinal or systemic problems rather than the classic allergic skin/ear pattern. Therefore, loss of appetite is the least likely clinical sign of allergies.
