What other things may trigger asthma in dogs?

In addition to allergens and irritants, the following triggers may lead to asthma in dogs:

- Cold air: Cold air can cause the airways to become inflamed and constricted, leading to an asthma attack.

- Exercise: While exercise is generally beneficial for dogs, it can sometimes trigger asthma in some individuals. This is thought to be due to the increased respiratory rate and exertion associated with exercise, which can lead to an accumulation of mucus in the airways.

- Stress: Stress can worsen asthma symptoms in dogs, as stress hormones can cause the airways to become more reactive and sensitive to triggers.

- Obesity: Obesity can contribute to asthma by causing increased pressure on the chest, leading to difficulty breathing. Additionally, obesity can also lead to decreased lung capacity, making dogs more susceptible to airway inflammation.

- Gastroesophageal reflux: Gastroesophageal reflux, also known as heartburn, can also be a trigger for asthma in dogs. The regurgitation of stomach contents into the esophagus and airways can cause inflammation and irritation, leading to an asthma attack.
