When dogs sneeze, have runny noses, and cough, is it just a simple case of "catching a cold"? Actually, dogs can catch colds, and these colds can sometimes reflect deeper health problems. This article will break down the causes, symptoms, and potential risks of canine colds, and explain how to detect problems early through pet checkups to protect your furry friend's health.

Mild colds in dogs may resolve on their own within a few days.If cold symptoms persist for more than 5 days, cough worsens, or breathing becomes difficultA dog's cold may not be as simple as a common cold. Based on Hong Kong veterinary clinical experience, a dog's cold may reflect the following potential health problems:
- Tracheal collapse
Commonly seen in small dogs (such as Pomeranians or Poodles), the cough sounds like a "goose quack," and the symptoms worsen when a dog has a cold. - Heart disease
Dogs with heart disease are prone to problems such as coughing, wheezing, and decreased exercise endurance, and are more likely to develop heart failure. - Decreased immunity
Dogs with chronic diseases such as diabetes, kidney disease, and tumors recover more slowly from a cold and are more prone to complications. - Periodontal disease or nasal infection
It can cause cold-like symptoms, such as runny nose, sneezing, and bad breath.
