Can Dogs Get Asthma? Identifying the Signs and When to Call the Vet

Can dogs get asthma? The answer is yes, dogs can develop asthma, though it is less common in dogs than in cats. Dog asthma, also referred to as allergic bronchitis, is a chronic respiratory condition that causes inflammation and narrowing of the airways, making it difficult for affected dogs to breathe normally. If your dog has been coughing, wheezing, or showing any signs of breathing difficulty, it is worth exploring whether asthma may be the cause. Our veterinary team at Kryder + Harr Veterinary Clinic in Granger, IN is experienced in diagnosing and managing respiratory conditions in dogs.

What Is Dog Asthma?

Dog asthma is a chronic inflammatory condition of the lower airways. It typically develops as an allergic response to environmental triggers, causing the bronchi and bronchioles (the small airways of the lungs) to become inflamed and constricted. In severe cases, these airways can spasm, causing an asthma attack. While dog asthma is not curable, it is very manageable with the right treatment plan. Middle-aged dogs and small breeds may be somewhat more prone to developing asthma, though any dog can be affected.

Signs of Asthma in Dogs

Recognizing the symptoms of dog asthma can help you get your dog help before a minor issue becomes a serious episode. Common signs include:

• Persistent dry or hacking cough
• Wheezing or high-pitched breathing sounds
• Labored breathing or rapid breathing
• Open-mouth breathing (uncommon but indicates distress)
• Exercise intolerance such as tiring easily or reluctance to be active
• Blue-tinged gums or tongue in severe cases (cyanosis which is an emergency)
• Crouching low to the ground during a breathing episode

Symptoms may be intermittent and may worsen when your dog is exposed to their specific triggers. Some dogs have mild, occasional flare-ups; others may experience more frequent or severe episodes.

What Triggers Dog Asthma?

Dog asthma attacks are typically triggered by inhaled allergens or irritants. Common triggers include:

• Cigarette smoke, one of the most significant airway irritants for dogs
• Pollen, mold, and grass
• Dust mites and household dust
• Air fresheners, candles, and aerosol sprays
• Cat litter dust (particularly clay-based litters)
• Cleaning products and chemical fumes
• Perfumes and scented products

Identifying and reducing exposure to your dog’s specific triggers is an important part of managing canine asthma. Keeping an environmental diary can help you and your veterinarian pinpoint patterns.

How Is Dog Asthma Diagnosed?

Because many respiratory conditions share similar symptoms, diagnosing dog asthma requires a thorough veterinary evaluation. At Kryder + Harr Veterinary Clinic, the diagnostic process typically includes a full physical exam, chest X-rays to evaluate the lungs and airways, and bloodwork to rule out infection or other systemic disease. Heartworm testing is also typically included, since heartworm disease can cause similar respiratory symptoms in dogs.

Ruling Out Other Respiratory Conditions

Conditions like kennel cough, pneumonia, heart disease, tracheal collapse, and lungworm infection can all cause coughing and breathing difficulties similar to asthma. This is why a thorough workup is essential before arriving at a diagnosis of canine asthma.

Treatment Options for Dog Asthma

The goal of treating dog asthma is to reduce inflammation, prevent airway spasm, and improve your dog’s quality of life. Treatment plans typically include:

• Corticosteroids: Reduce airway inflammation. These may be given orally, by injection, or in some cases via inhaler.
• Bronchodilators: Open the constricted airways and make breathing easier. Often used alongside steroids during acute episodes.
• Allergen avoidance: Identifying and minimizing triggers is essential for long-term management.
• Environmental modifications: Air purifiers, switching to low-dust litter, avoiding smoke exposure, and using fragrance-free products can all help.

Inhalers for Dogs

Just like humans, dogs can use inhalers which is delivered through a specially designed spacer device called an AeroDawg chamber. Inhaled medications are becoming increasingly popular in treating canine asthma because they deliver medication directly to the lungs with fewer systemic side effects. Your veterinarian will show you how to administer inhaled medications comfortably and effectively.

What to Do During a Dog Asthma Attack

If your dog is having an asthma attack and you notice they’re struggling to breathe, breathing with their mouth open, or showing blue gums, this is a veterinary emergency. Stay calm, limit your dog’s exertion, move them to fresh air away from any potential triggers, and get to an emergency veterinary clinic immediately. Time is critical during a severe respiratory episode.

Living Well with a Dog with Asthma

Dog asthma is a lifelong condition, but many dogs with asthma live full, happy, active lives with proper management. Regular follow-up appointments at Kryder + Harr Veterinary Clinic allow your veterinarian to monitor your dog’s respiratory health, adjust medications as needed, and catch any changes before they become serious problems. If your dog has been coughing or showing any signs of breathing difficulty, do not delay. Give us a call at (574) 277-6533 and let us help you get to the bottom of it.
