What Is Asthma in Dogs?

Asthma isn’t exclusive to humans—dogs can suffer from it too. Known as canine asthma or allergic bronchitis, this respiratory issue causes inflammation and constriction of the airways, leading to breathing difficulties. Common triggers include environmental allergens like dust, pollen, mold, and smoke.

Asthma in dogs is more commonly seen in smaller breeds and middle-aged dogs, but it can occur in any breed or age group. With proper care and early diagnosis, your dog can lead a happy, active life.

Common Causes of Dog Asthma

Allergic reactions usually cause dog asthma. Here are some of the most common triggers:

• Environmental allergens Include Pollen, mold, dust mites, and certain household cleaning products.
• Smoke: Cigarette smoke or fumes from wood stoves and fireplaces.
• Aerosols and sprays include air fresheners, perfumes, and insecticides.
• Pollution: Poor air quality can aggravate the condition.
• Exercise or stress: In some cases, strenuous activity or emotional stress can trigger asthma attacks.

Identifying and removing these triggers from your dog’s environment can significantly help reduce the frequency and severity of asthma symptoms.

Signs and Symptoms of Asthma in Dogs

Early detection plays a critical role in managing asthma. Keep an eye out for these symptoms:

• Persistent coughing: Often dry, hacking, or wheezing in nature.
• Labored breathing: Your dog may breathe heavily or appear to be struggling for air.
• Wheezing sounds: Whistling or wheezing noises while breathing.
• Exercise intolerance: Your dog may become tired quickly during walks or play.
• Open-mouth breathing: This can be a sign of respiratory distress.
• Bluish gums or tongue: Indicates a lack of oxygen and requires immediate veterinary attention.

If you notice any of these symptoms, it’s essential to consult your vet right away. Asthma attacks can escalate quickly and may become life-threatening if untreated.

Diagnosing Asthma in Dogs

There’s no single test to diagnose asthma in dogs, so your vet may recommend a combination of the following:

• Physical examination: Listening to your dog’s lungs for wheezing or abnormal sounds.
• Chest X-rays: Used to detect inflammation or fluid buildup in the lungs.
• Blood work: Helps eliminate the possibility of infections or other underlying issues.
• Allergy screening: Determines if specific allergens are contributing to your dog's asthma symptoms.
• Bronchoscopy (in some cases): A camera is used to visualize the inside of the airways.

Your vet will consider all test results, symptoms, and your dog’s medical history to make a diagnosis.

How Is Dog Asthma Treated?

Although asthma can't be cured, it can be well-controlled with proper care. Below are some standard treatment methods:

1. Medications

• Bronchodilators: Help open up airways and ease breathing during attacks.
• Corticosteroids: Help decrease lung inflammation and minimize the risk of future asthma attacks.
• Antihistamines: May be prescribed if allergies are a known trigger.

These medications may be administered orally, through inhalers, or by injection, depending on the severity of the condition.

2. Inhalers for Dogs

Inhalers used for dogs are specially designed to deliver medication directly to the lungs. Your vet may prescribe a canine-specific inhaler with a spacer to ensure effective delivery.

3. Environmental Management

• Use air purifiers at home to reduce allergens and improve indoor air quality.
• Avoid smoking indoors or using harsh cleaning agents.
• Regularly vacuum and clean bedding and carpets.
• Bathe your dog with hypoallergenic shampoos.

What to Do During an Asthma Attack

In the event your dog is having an asthma episode:

• Remain calm – Dogs can sense your anxiety, and staying composed can help prevent their symptoms from getting worse.
• Move them to a well-ventilated area – Avoid hot, humid spaces.
• Provide fresh, cool water if your dog is alert and able to drink on their own.
• Contact your vet immediately – Asthma attacks can escalate fast and may require emergency care.

Can Dog Asthma Be Prevented?

While you may not be able to prevent asthma completely, there are steps you can take to reduce the likelihood of flare-ups:

• Identify and eliminate triggers in your home environment.
• Maintain your dog's healthy weight, as obesity can exacerbate breathing problems.
• Limit exposure to outdoor allergens during high-pollen seasons.
• Avoid stress and over-exercising, especially in dogs with a history of asthma.

Regular vet checkups can also help in early detection and better management of respiratory issues.

When to See a Vet

If your dog shows any signs of breathing difficulties, don’t delay a visit to the vet. Even mild coughing can develop into more serious conditions, such as chronic bronchitis or pneumonia, if left untreated. A vet can assess your dog’s health, provide medication, and recommend lifestyle changes to improve their breathing.
