What condition describes a chronic dry cough and respiratory distress in an older small-breed dog?

• A. Kennel Cough
• B. Canine Allergic Bronchitis
• C. Feline Asthma
• D. Canine Chronic Bronchitis

Answer: (B)

Chronic cough with dry hacking and noticeable breathing difficulty in an older small-breed dog points to allergic airway disease causing bronchial hyperreactivity. Canine allergic bronchitis arises from an atopy-like response to environmental allergens, leading to airway inflammation and constriction. This process often produces a persistent, dry cough and can progress to respiratory distress when airways are significantly narrowed. The pattern fits a small-breed dog more than large breeds, and the age suggests a chronic inflammatory airway problem rather than an acute infectious cause. Kennel cough tends to be an acute, self-limited infection of the trachea and bronchi, usually with a noticeable honking or dry cough but not the ongoing, progressive dyspnea seen with chronic allergic airway disease. Feline asthma is a condition of cats, involving bronchoconstriction and coughing in felines, not dogs. Canine chronic bronchitis can cause a long-standing cough, but it is typically productive, with mucus, rather than a dry cough, and the presentation is often not dominated by acute respiratory distress in an older small-breed dog. So the chronic dry cough with respiratory distress in this scenario most closely aligns with canine allergic bronchitis, reflecting eosinophilic or allergic airway inflammation driving bronchial hyperreactivity.
