What It Is?

Asthma, also known as allergic bronchitis, is often triggered by pollen, dust, smoke, mold, or other environmental irritants. Infections, stress, or extreme weather conditions can also exacerbate it.

Causes?

Asthma in dogs is often linked to allergic reactions. When exposed to allergens, the immune system overreacts, causing inflammation and excessive mucus production in the airways, making it hard for the dog to breathe. Chronic exposure to irritants like smoke or pollution can also contribute to asthma.

Additional info?

It can also be caused by food allergies and exercise, especially in brachycephalic breeds.
