Help: My Dog is Coughing in the Morning [Vet Advice]

This article was updated on May 1st, 2023

As a veterinarian, one thing that I see often is dogs that are coughing. The time of day that your dog is coughing and the frequency and help determine what is going on. Some dogs will just cough during the morning, some just at night and others will cough all the time. If your dog is coughing in the morning, there are some important things to consider.

Is my dog coughing in the morning different from coughing anytime during the day?

Coughing in the morning is most commonly due to fluid building up in your dog’s lungs. As your dog is sleeping, this fluid will accumulate, and once your dog wakes up, they will try to cough all this extra fluid up.

Coughing all day or late at night can mean that your dog has more severe issues going on, causing them to continue to cough.

Why is my dog coughing only in the morning?

These are some of the most common reasons that your dog may be coughing only in the morning:

• Heart disease
• Bronchitis
• Pneumonia
• Kennel Cough
• Allergies

Some of these issues will also cause your dog to cough all day and at night. For mild cases, you may only notice that your dog is coughing early in the morning, shortly after they get up. Usually, mild signs of these diseases will just cause your dog to cough in the morning. As your dog’s disease progresses, you may notice that your dog is coughing more frequently and during the day.

What are some other signs I might see?

If your dog is coughing in the morning only, you must determine the cause. Many times, dogs with bronchitis or pneumonia will also have other signs such as lethargy, not eating or drinking, and discharge from their nose. If your dog has early heart disease, you may only notice an occasional cough in the mornings.

Dogs with kennel cough or allergies commonly will be feeling just fine; they will just have a slight cough.

What do I need to do if my dog is coughing?

Once you figure out why your dog is coughing, you will need to treat these issues. If your dog has pneumonia or bronchitis, they will need to see your vet for antibiotics to help clear these infections. For dogs with allergies, there are some at home remedies that you can try to see if your dog will stop coughing. Things such as allergy medication and steam can help your dog stop coughing and feel much better.

When do I need to see my vet?

Sometimes you can easily stop your dog’s coughing at home with just a few simple changes, but sometimes your dog will need to see your vet. These are some reasons that you should bring your dog to the vet for coughing:

• The coughing becomes more frequent
• They are having issues breathing
• Their cough is not improving
• Their tongue is blue or purple
• They are lethargic
• They are not eating
• They are also vomiting or having diarrhea

Your vet will be able to quickly assess your dog to see why your dog is coughing and start them on medication.
