In this article, we will explore potential causes of breathing difficulties in dogs and cats, offer advice on immediate steps to take, and discuss when euthanasia might be considered.

Potential Causes of Breathing Difficulties in Dogs

1. Kennel Cough

Overview

Kennel cough, also known as canine infectious tracheobronchitis, is a highly contagious respiratory disease that affects dogs. It's commonly contracted in environments where dogs are in close contact, such as kennels, dog parks, or grooming facilities. The condition is characterized by inflammation of the trachea and bronchi, and while it is generally not life-threatening, it can be severe in puppies, older dogs, or those with compromised immune systems.

Symptoms

The hallmark symptom of kennel cough is a persistent, dry, hacking cough that often sounds like the dog has something stuck in its throat. Other symptoms may include:

• Retching and gagging, especially after coughing

• Runny nose and sneezing

• Mild fever

• Lethargy

• Loss of appetite

Causes

Kennel cough can be caused by several pathogens, most commonly:

• Bordetella bronchiseptica bacterium: Often involved in kennel cough, it can also be accompanied by viral infections.

• Canine parainfluenza virus

• Canine adenovirus type 2

• Canine distemper virus

• Canine influenza Virus

• Canine respiratory coronavirus

• Canine herpes-virus-1

• Canine distemper virus

Many times there is a viral infection that can be worsened by secondary bacterial infection. These pathogens spread through airborne droplets when an infected dog coughs or sneezes, or through direct contact with contaminated surfaces or other dogs.

Treatment

Most cases of kennel cough resolve on their own within a few weeks, but treatment can help alleviate symptoms and prevent secondary infections. Treatment may include:

• Cough suppressants: To help manage the cough and improve comfort.

• Antibiotics: In cases where a bacterial infection is suspected or confirmed.

• Rest: Limiting physical activity to prevent exacerbating the cough.

• Hydration and nutrition: Ensuring the dog remains hydrated and continues to eat.

Prevention

Vaccination can help prevent kennel cough. The Bordetella vaccine is often administered annually or more frequently for dogs at high risk. Other vaccines such as the canine influenza vaccine may be recommended as well. Good hygiene practices and avoiding crowded dog environments during outbreaks can also reduce the risk.

2. Pneumonia

Overview

Pneumonia in dogs is an inflammatory condition of the lungs and airways, often caused by bacterial, viral, fungal, or parasitic infections. It can range from mild to severe and requires prompt veterinary attention.

Symptoms

Symptoms of pneumonia in dogs can include:

• Coughing (moist or productive)

• Difficulty breathing or rapid breathing

• Wheezing or crackling sounds in the chest

• Fever

• Nasal discharge

• Lethargy and weakness

• Loss of appetite and weight loss

Causes

Pneumonia can be caused by various pathogens and conditions, including:

• Bacterial pneumonia: Often caused by bacteria such as Streptococcus, Staphylococcus, or Escherichia coli. Aspiration pneumonia, resulting from inhaling foreign substances like vomit, can also cause bacterial infection.

• Viral pneumonia: Viruses like canine distemper or canine influenza can lead to pneumonia.

• Fungal pneumonia: Inhalation of fungal spores, such as Blastomyces or Histoplasma, can cause fungal infections in the lungs.

• Parasitic pneumonia: Lungworms or other parasites can invade the respiratory system.

Treatment

The treatment for pneumonia in dogs depends on the underlying cause and severity but may include:

• Antibiotics or antifungals: To treat bacterial or fungal infections.

• Oxygen therapy: For dogs with severe respiratory distress.
