As responsible pet owners, understanding the nuances of canine respiratory health is crucial. While common ailments like kennel cough often resolve on their own, a more serious respiratory disease has emerged, presenting with pneumonia-like symptoms and a longer incubation period. This article aims to differentiate between kennel cough, canine pneumonia, and other upper respiratory infections in dogs, providing insights into their causes, symptoms, and available treatments. Early recognition and appropriate veterinary care are paramount to ensuring your dog’s well-being.
Canine Pneumonia: A Growing Concern
Since the summer of 2022, a heightened concern has surrounded a specific respiratory disease in dogs, particularly noted in regions like New Hampshire and northern Massachusetts. By the summer of 2023, cases of this more severe form of dog pneumonia had spread across the United States, with reports emerging from Florida, Oregon, California, Michigan, Texas, Ohio, Wyoming, and North Carolina. Unlike the typical kennel cough, which usually manifests symptoms within a week of exposure and clears up within two weeks, this new strain can have an incubation period of one to three weeks before rapidly progressing to pneumonia.
Diagnosing Canine Pneumonia
Distinguishing pneumonia from milder respiratory infections in its early stages can be challenging, as symptoms like a honking cough and nasal discharge can overlap with kennel cough. However, dogs developing pneumonia may exhibit more severe signs, including lethargy, refusal to eat, difficulty breathing, and fever. If your dog displays any of these advanced symptoms, immediate veterinary attention is essential. Veterinarians employ a range of diagnostic tests to confirm pneumonia, which may include bacterial cultures, canine respiratory panels to identify specific pathogens, tracheal wash cytology, and virus isolation, in addition to standard blood work.
Understanding the Causes of Dog Pneumonia
The exact causes of this particular respiratory disease remain under investigation. Similar to kennel cough, it is believed to spread among dogs in close contact in environments such as daycare facilities, shelters, kennels, groomers, and dog parks through shared items. However, some cases have occurred without any known dog-to-dog contact, and the extended incubation period complicates efforts to trace the disease’s origin in specific instances.
Treatment for Dog Pneumonia
Treatment for dogs diagnosed with pneumonia typically involves hospitalization for overnight care and aggressive medication. Supportive therapies may include oxygen administration and nebulizers. Unfortunately, some dogs do not respond well to conventional treatments. Diagnostic tests have thus far shown negative results for common culprits like Bordetella, influenza, and coronavirus. For owners who already partner with a holistic veterinarian, consulting them for advice on at-home management alongside professional guidance is recommended. However, due to the critical nature of some pneumonia cases, hospitalization is often necessary.
Upper Respiratory Infections in Dogs: A Broad Category
An upper respiratory infection (URI) in dogs encompasses any condition affecting the respiratory system, including the lungs, airways, and nasal passages. This is also commonly referred to as canine respiratory disease. Understanding the diverse range of symptoms and causes is key to providing appropriate care.
Symptoms of Respiratory Infection in Dogs
The presentation of symptoms can vary widely depending on the specific infection and its underlying cause. However, several common signs warrant attention:
- Coughing: A persistent dry or moist cough, sometimes producing white or yellow foamy discharge, is a hallmark symptom. It may worsen with physical activity or excitement.
- Sneezing: Frequent sneezing, often accompanied by nasal discharge, is another indicator.
- Difficulty Breathing: Labored or shallow breathing, rapid respiration, or noticeable shortness of breath can signify a serious infection like pneumonia.
- Fever: An elevated body temperature, exceeding 101.5°F (38.6°C), strongly suggests an infection is present.
- Loss of Appetite: A decreased interest in food can signal a more severe infection, particularly pneumonia.
- Lethargy: Dogs suffering from serious infections, such as pneumonia, may appear unusually tired or weak.
- Nasal Discharge: A runny nose or discharge from the nostrils indicates an issue within the upper respiratory tract.
- Eye Discharge: Some respiratory infections can lead to eye discharge, similar to conjunctivitis.

Causes of Respiratory Disease and Infection in Dogs
A variety of pathogens can trigger respiratory infections in canines, including viruses, bacteria, fungi, and parasites. Some of the most prevalent causes include:
- Canine Influenza: A highly contagious viral infection that produces respiratory symptoms akin to the human flu.
- Kennel Cough: Also known as infectious tracheobronchitis, this is a contagious respiratory illness caused by a mix of bacteria and viruses, often spreading rapidly in communal environments like kennels and shelters. For more on this, explore the kennel cough vaccine discussion.
- Pneumonia: An infection of the lungs that can stem from bacterial, viral, or fungal origins.
- Canine Distemper Virus: A serious viral infection that can cause respiratory symptoms alongside potentially fatal neurological effects.
- Bordetella Bronchiseptica: A bacterium frequently implicated as a cause of kennel cough.
- Fungal Infections: Conditions like blastomycosis, histoplasmosis, and aspergillosis can affect a dog’s respiratory system.
- Parasites: Lungworms and heartworms are examples of parasites that can impact the respiratory system.
Factors such as stress, overcrowded living conditions, poor nutrition, compromised immune systems, and exposure to infected animals or environments significantly increase a dog’s risk of contracting a respiratory infection. Supporting your dog’s immune system is crucial, and immune system boosters for dogs can play a role.
Natural Remedies for Respiratory Infection in Dogs
While professional veterinary care is paramount, especially for suspected pneumonia, several natural remedies may help alleviate symptoms of milder respiratory infections:
- Steam Therapy: Running a steamy shower can help open airways and ease congestion. Allow your dog to breathe the moist air without direct exposure to the hot water.
- Manuka Honey: Possessing natural antibacterial and anti-inflammatory properties, Manuka honey can soothe a sore throat and cough. A small amount can be mixed into food or offered directly. Discover more about Manuka honey for your dog.
- Echinacea: This herb is known to support the immune system and reduce inflammation. It can be administered as a tincture or supplement.
- Vitamin C: A vital nutrient for immune support and inflammation reduction. Incorporate vitamin C-rich foods like strawberries and bell peppers into the diet, or opt for a natural Vitamin C supplement.
- Fluids: Maintaining hydration is critical, particularly if your dog has a fever or reduced appetite. Broth, including low-sodium or homemade bone broth, can be beneficial. Explore natural antibiotic remedies that may help.
Differentiating Kennel Cough from Upper Respiratory Infections
It’s important to understand that kennel cough and upper respiratory infections (URIs) are distinct, though they share overlapping symptoms. Kennel cough, or infectious tracheobronchitis, is a highly contagious respiratory illness caused by various pathogens and typically transmitted through direct contact with infected dogs. Its hallmark is a persistent dry cough, often accompanied by gagging, which can last for weeks. Nasal discharge, sneezing, and fever may also be present.
A URI, on the other hand, is a broader term for infections affecting the nose, throat, or sinuses. URIs can arise from diverse viral or bacterial causes and manifest as coughing, sneezing, nasal discharge, and fever. Crucially, URIs can sometimes lead to secondary complications like pneumonia. While kennel cough is a specific type of respiratory illness, URIs encompass a wider range of conditions that aren’t always linked to exposure in communal dog environments.
Other Common Canine Respiratory Infections
Beyond kennel cough and pneumonia, other respiratory conditions can affect dogs:
Canine Chronic Bronchitis
This condition involves chronic inflammation and irritation of the airways, often referred to as COPD or chronic bronchitis complex. Long-term exposure to irritants such as cigarette smoke, dust, and pollution is thought to be a contributing factor. Certain breeds, particularly small and brachycephalic (flat-faced) dogs, are more prone to developing it. Symptoms include coughing, wheezing, exercise intolerance, difficulty breathing, lethargy, decreased appetite, and weight loss. Chronic bronchitis can also predispose dogs to secondary infections, including pneumonia, due to persistent airway inflammation and damage.
Eosinophilic Bronchopneumopathy (EBP)
EBP is characterized by inflammation and an elevated presence of eosinophils—a type of white blood cell—in the airways and lungs. It is believed to be an immune system response triggered by inhaled irritants, allergens, or parasites. EBP is more commonly diagnosed in young to middle-aged dogs, with certain breeds like German Shepherds and Rottweilers being more susceptible. The symptoms often mirror those of general respiratory infections and canine chronic bronchitis, and like other inflammatory airway diseases, EBP can also lead to secondary pneumonia.
While conventional treatments for these conditions may involve medications, hydration, and nutritional support, with hospitalization in severe instances, fostering a robust immune system is paramount. This begins with a high-quality, whole-food diet.
Navigating Diagnosis: Canine Respiratory Infection, Kennel Cough, or Pneumonia?
As pet owners, accurately diagnosing a canine respiratory issue can be daunting. If you have any uncertainty, consulting a veterinarian is the safest course of action. They can utilize diagnostic testing to pinpoint the exact ailment affecting your dog. It’s critical to avoid mistaking a mild respiratory illness for a severe condition like canine pneumonia.
Therefore, if your dog exhibits difficulty breathing, lethargy, or a lack of appetite, seek immediate veterinary care for a proper diagnosis, especially if pneumonia is suspected. Do not attempt to manage pneumonia at home without close veterinary supervision.
