1. Infections and Dog Cough

Infections are a common reason dogs cough. These infections can be caused by viruses, bacteria, fungi, or parasites, affecting different parts of the respiratory system. Understanding the specific type of infection is crucial for effective treatment.

1.1. Viral Infections

Viral infections like canine influenza virus (CIV) and kennel cough (infectious tracheobronchitis) are highly contagious respiratory diseases. They often result in a harsh, hacking cough.

• Canine Influenza Virus (CIV): Similar to human influenza, CIV can cause fever, lethargy, and a persistent cough. Vaccination can help prevent CIV.
• Kennel Cough: This is a broad term for several highly contagious respiratory infections, often occurring in places where dogs congregate, such as kennels, dog parks, and grooming facilities.

1.2. Bacterial Infections

Bacterial infections can occur as secondary infections following a viral infection. Common bacterial culprits include Bordetella bronchiseptica, which is a primary agent in kennel cough, and other bacteria that can cause pneumonia.

• Bordetella bronchiseptica: This bacterium is a major cause of kennel cough, leading to inflammation of the trachea and bronchi.
• Pneumonia: Bacterial pneumonia can result from untreated respiratory infections or aspiration. It causes inflammation and fluid buildup in the lungs.

1.3. Fungal Infections

Fungal infections, such as aspergillosis and blastomycosis, can also cause coughing in dogs, especially in certain geographic regions.

• Aspergillosis: This infection is caused by Aspergillus fungi, often found in soil and decaying vegetation. It can affect the nasal passages and lungs.
• Blastomycosis: Blastomyces dermatitidis is a fungus found in moist soil and decaying organic matter. Inhaling the spores can lead to lung infection and coughing.

1.4. Parasitic Infections

Parasites like lungworms and heartworms can lead to coughing. These parasites affect the respiratory and cardiovascular systems, causing inflammation and irritation.

• Lungworms: These parasites reside in the lungs and airways, causing inflammation and coughing.
• Heartworms: While primarily affecting the heart, heartworms can also cause lung inflammation and coughing. Mosquitoes transmit these parasites.

2. Chronic Bronchitis and Dog Cough

Chronic bronchitis in dogs involves persistent inflammation of the airways, leading to a chronic cough. This condition is often diagnosed when other causes of coughing have been ruled out.

2.1. Symptoms of Chronic Bronchitis

The main symptom is a dry, hacking cough that worsens with exercise or excitement. Over time, the cough can become more frequent and severe.

2.2. Diagnosis and Management

Diagnosis typically involves ruling out other causes of coughing through tests like X-rays, bronchoscopy, and airway sampling. Management focuses on reducing inflammation and controlling symptoms.

2.3. Treatment Options

• Corticosteroids: These medications help reduce inflammation in the airways.
• Bronchodilators: These drugs help open up the airways, making breathing easier.
• Cough Suppressants: These can provide temporary relief from coughing.
• Environmental Management: Avoiding irritants like smoke, dust, and allergens can help manage symptoms.

3. Allergies and Dog Cough

Allergies can cause coughing in dogs due to inflammation in the airways and lungs. Allergic reactions can be triggered by various substances in the environment.

3.1. Common Allergens

• Pollen: Seasonal allergies to tree, grass, and weed pollen are common.
• Dust Mites: These microscopic creatures thrive in bedding, carpets, and upholstery.
• Mold Spores: Mold can grow indoors and outdoors, especially in damp environments.

3.3. Diagnosis and Treatment

Allergy testing can help identify specific allergens. Treatment options include:

• Antihistamines: These medications can help reduce allergic reactions.
• Corticosteroids: These reduce inflammation.
• Allergen-Specific Immunotherapy (ASIT): Also known as allergy shots, this involves gradually exposing the dog to small amounts of the allergen to desensitize the immune system.
• Dietary Changes: If food allergies are suspected, a hypoallergenic or limited-ingredient diet may be recommended.
• Environmental Control: Reducing exposure to allergens in the environment, such as regular cleaning and using air purifiers.

4. Reverse Sneezing and Dog Cough

Reverse sneezing can often be mistaken for coughing. It involves a rapid and forceful inhalation of air through the nose, creating a snorting or gagging sound.

4.1. What is Reverse Sneezing?

Reverse sneezing occurs when something irritates the back of a dog’s nasal passages, such as allergens, irritants, or nasal mites.

4.2. Symptoms of Reverse Sneezing

During a reverse sneeze, a dog will typically:

• Extend its neck.
• Stand still.
• Forcefully inhale through the nose.
• Make a snorting or gagging sound.

4.3. When to Worry

Occasional reverse sneezing is usually harmless. However, if it becomes frequent, severe, or is accompanied by nasal discharge or facial changes, consult a vet.

5. Heart Disease and Dog Cough

Heart disease can cause coughing in dogs due to fluid buildup in the lungs (pulmonary edema) or enlargement of the heart, which can compress the trachea.

5.1. Types of Heart Disease

• Mitral Valve Endocardiosis (Degeneration): This is the most common heart disease in older small-breed dogs, involving thickening and degeneration of the mitral valve.
• Dilated Cardiomyopathy (DCM): DCM involves enlargement and weakening of the heart muscle, reducing its ability to pump blood effectively.
• Congestive Heart Failure (CHF): CHF occurs when the heart cannot pump enough blood to meet the body’s needs, leading to fluid buildup in the lungs and other tissues.

5.2. Symptoms of Heart Disease

• Coughing: Especially at night or after exercise.
• Difficulty Breathing: Increased respiratory rate or effort.
• Lethargy: Reduced energy levels.
• Exercise Intolerance: Getting tired more easily during physical activity.

Diagnosis involves a physical exam, chest X-rays, echocardiography, and blood tests. Treatment aims to lower blood pressure in the lungs and manage underlying causes.

• Sildenafil: This medication helps relax the pulmonary arteries, reducing blood pressure.
• Oxygen Therapy: Supplemental oxygen can help improve oxygen levels in the blood.
• Treatment of Underlying Conditions: Addressing the root cause, such as heartworm disease or chronic lung disease.

8. Heartworm Disease and Dog Cough

Heartworm disease is a serious and potentially fatal condition caused by parasitic worms that live in the heart, lungs, and associated blood vessels of affected animals. Mosquitoes transmit heartworms.

8.1. Transmission and Life Cycle

When a mosquito bites an infected dog, it picks up heartworm larvae (microfilariae). The mosquito then transmits these larvae to another dog during a subsequent bite. The larvae migrate to the heart and lungs, where they mature into adult heartworms.

8.2. Symptoms of Heartworm Disease

• Coughing: Often mild and persistent.
• Exercise Intolerance: Getting tired easily.
• Lethargy: Reduced energy levels.
• Difficulty Breathing: Increased respiratory rate and effort.
• Weight Loss: Loss of appetite.
• Swollen Abdomen: Fluid accumulation.

8.3. Diagnosis and Treatment

Diagnosis involves blood tests to detect heartworm antigens or microfilariae. Treatment is complex and involves killing adult heartworms and managing inflammation.

• Adulticide Therapy: This involves a series of injections to kill adult heartworms.
• Corticosteroids: These reduce inflammation.
• Rest: Restricting exercise during treatment is crucial to prevent complications.
• Heartworm Prevention: Regular use of heartworm preventatives is essential to protect dogs from infection.
