Just like people, dogs can develop asthma—although it’s less common. When asthma occurs, it’s usually the result of an allergic reaction that causes inflammation in the airways. This inflammation leads to spasms in the airway muscles, making it difficult for your dog to breathe.
Asthma is most often seen in middle-aged dogs and some young dogs, and smaller breeds tend to be more at risk.
Symptoms of Asthma in Dogs
Asthma attacks in dogs can range from mild to severe. Common symptoms of asthma include:
- Persistent or dry coughing
- Heavy panting with mouth open
- Wheezing or labored breathing
- Bluish-colored gums (a sign of low oxygen)
- Loss of appetite or decreased energy
If you notice any of these signs, contact your veterinarian immediately. Asthma attacks can look similar to other serious conditions—such as heart disease, infection, or heartworm—so an accurate diagnosis is essential.
How Vets Diagnose Asthma
There isn’t a single test for canine asthma. Instead, your vet will start with a physical exam and may recommend additional diagnostic tests such as chest X-rays, heartworm testing, or blood work. These help rule out other causes with similar symptoms and confirm whether your dog’s breathing issues are caused by asthma.
In some cases, your vet may ask you to record your dog’s breathing episode at home to provide more information for an accurate assessment of your pet’s condition.
Treatment for Asthma in Dogs
Once asthma is diagnosed, your vet will determine the best treatment plan based on your dog’s needs.
- Anti-inflammatory steroids to help control symptoms may be prescribed to reduce airway inflammation and prevent long-term damage.
- In some cases, a dog-specific inhaler containing albuterol sulfate (commonly sold as Ventolin or Proventil) may be used to relax airway muscles and make breathing easier.
Never administer human medications or inhalers without veterinary guidance—many are toxic to dogs. Always make an appointment with your vet for proper treatment and dosing instructions.
Managing and Preventing Asthma Attacks
The best way to protect your pet is to reduce exposure to triggers that can cause asthma attacks in dogs. Common irritants include:
- Smoke from cigarettes, fireplaces, or cooking
- Household cleaners, aerosols, or strong perfumes
- Dust, pollen, and mold
Keeping your home clean, avoiding scented products, and using air purifiers can help reduce airborne allergens. Regular checkups allow your veterinarian to monitor your dog’s condition and adjust treatment as needed to manage symptoms and prevent long-term complications.
When To See a Veterinarian
If your dog is coughing, wheezing, or showing signs of difficulty breathing, don’t wait. Asthma attacks can quickly become serious. Please make an appointment with Hershey Veterinary Hospital for an evaluation.
If your pet is struggling to breathe or has blue gums or tongue, seek emergency care immediately.
