Asthma in Dogs
Asthma (also known as allergic bronchitis) is an inflammatory disease of the trachea and the bronchi that develops when the smooth muscle of the bronchi constricts, blocks the airway, and triggers the release of histamines that combat allergens. When this occurs the airway becomes obstructed, fills with mucous, and causes spasms, shortness of breath, and wheezing. The condition is often triggered by exposure to environmental allergens including cigarette smoke, dust, hair spray, and perfume.
Chronic allergic bronchitis is a breathing disorder that can develop anytime or may be caused by seasonal allergies. It is brought on by physical activity and causes a persistent dry, hacking cough.
Dogs can also develop Allergic Bronchiolites, an inflammation of the lower portion of the airway, or Bronchitis, an inflammation of the bronchial airways that may extend into the lungs.
Symptoms of Asthma in Dogs
- shortness of breath
- dry, hacking cough

- bluish mucous membranes (in severe cases - emergent)
Limit your dog's exposure to potential irritants including cigarette smoke, dust, hair spray, perfume, and harmful household chemicals. It is also important to visit the vet anytime your dog experiences breathing problems.
