Kennel cough is a highly contagious respiratory infection in dogs, formally known as canine infectious respiratory disease (CIRD). It’s often characterized by a persistent, dry, hacking cough, similar to the sound of a dog trying to clear its throat or a cat coughing up a hairball.

Despite its alarming symptoms, kennel cough is typically self-limiting and similar to the common cold in humans.

That means natural remedies are often enough to manage kennel cough and alleviate symptoms. But which natural options are best for kennel cough in dogs? Let's take a closer look below. But first, I want to clear up what kennel cough is, and some common kennel cough symptoms.

Understanding Kennel Cough In Dogs

Kennel cough infection is primarily caused by the airborne bacterium Bordetella bronchiseptica, but it can also result from viral agents such as canine parainfluenza virus or adenovirus. These pathogens invade the upper respiratory tract, leading to irritation and inflammation. Dogs with weakened immune systems are particularly vulnerable, as their defenses may not be strong enough to fend off these infections.

Environmental factors also play a significant role. Crowded, warm, and poorly ventilated spaces, such as boarding kennels, shelters, or even dog daycare facilities, can facilitate the spread of kennel cough. Additionally, stress from travel or changes in routine can lower a dog’s immunity, making them more susceptible.

Kennel cough spreads quickly through airborne droplets when an infected dog coughs, sneezes, or barks. It can also be transmitted via shared surfaces like water bowls, toys, or leashes. Even a brief encounter with an infected dog at a park or vet clinic can expose your pet to the illness.

Once exposed, dogs may develop symptoms within 2 to 10 days, during which they're highly contagious. This underscores the importance of isolating dogs with kennel cough to prevent it from spreading to others.

Symptoms Of Kennel Cough In Dogs

The hallmark symptom of kennel cough is a persistent, dry hacking cough that can sound like something is stuck in your dog’s throat. It’s often described as loud, frequent, and disruptive, much like a cat trying to cough up a hairball. Some dogs may also retch or produce a foamy discharge after coughing.

In addition to the cough, symptoms can include sneezing, nasal discharge, and watery, runny eyes. While clear discharge is generally harmless, cloudy or discolored mucus may indicate a secondary infection.

Most cases of kennel cough are mild, with symptoms lasting about a week. However, some dogs may exhibit reduced appetite, lethargy, or even fever, signaling a more serious infection.

If your dog has difficulty breathing, a high fever, or a complete loss of appetite, it’s time to consult a veterinarian. Severe cases, especially in puppies or dogs with pre-existing conditions, can progress to pneumonia or other complications, requiring prompt medical intervention.

Natural Kennel Cough Treatments

If your dog has kennel cough, what should you do? I recommend natural kennel cough treatment with the methods below.

Here's why:

1. Functional Mushrooms

Mushrooms like reishi, shiitake, and chaga are powerhouses for immune support. Reishi has antiviral and antibacterial properties, shiitake soothes supports a ealthy inflammation response, and chaga delivers potent antioxidants to combat infections. These mushrooms also support overall lung, liver, and gut health, making them excellent allies for dogs battling kennel cough.

For best results, use dried mushrooms or powdered supplements derived from whole mushroom fruiting bodies, not mycelium (the root system), as the fruiting bodies contain higher levels of beta-glucans—the compounds responsible for functional effects. Adjust doses based on your dog’s weight. For example, if a product is meant for a 150-pound human, give 1/10th of the dose to a 15-pound dog.

2. Probiotics

Gut health plays a vital role in maintaining a strong immune system. Probiotics introduce beneficial bacteria to your dog’s digestive system, which can help fend off harmful pathogens and support a faster recovery from respiratory infections like kennel cough. Look for probiotic supplements with at least 10 billion CFUs for general immune support or up to 25–50 billion CFUs if your dog’s symptoms are more severe.

To enhance probiotic effectiveness, include prebiotic foods in your dog’s diet, such as garlic, raw honey, and mushrooms. Prebiotics feed the probiotics, ensuring they thrive and deliver maximum benefits to your dog’s gut and immune system.

3. Garlic

Fresh garlic is a natural immune supporter. It's packed with essential nutrients like vitamin A, sulfur, zinc, and B vitamins, all of which help your dog combat infections and maintain a healthy gut. To use garlic safely, chop fresh, organic cloves and let them sit for 10 minutes to activate their functional compounds.

Mix the garlic into your dog’s food, using a dose of 1/3 teaspoon for every 10 pounds of body weight daily. Avoid using garlic for pregnant dogs or those with certain blood disorders, as it may not be suitable in those cases.

4. Manuka Honey

Manuka honey offers soothing relief for sore throats while delivering antimicrobial benefits that fight the bacteria and viruses associated with kennel cough. Its natural compounds, such as methylglyoxal (MGO) and dihydroxyacetone (DHA), make it a potent remedy for calming respiratory irritation and supporting immune function.

Choose Manuka honey with a Unique Manuka Factor (UMF) of 10 or higher for maximum benefits. Offer your dog the following doses twice daily: 1/2 teaspoon for dogs under 20 pounds, 1 teaspoon for dogs between 20 and 60 pounds, and 2 teaspoons for larger dogs. Avoid giving honey to diabetic dogs or puppies under one year old due to potential health risks.

5. Rose Hips

Rose hips are a rich, natural source of vitamin C, which plays a crucial role in supporting the immune system and aiding recovery from infections. Unlike synthetic vitamin C supplements, rose hips provide additional antioxidants and nutrients that support overall health without causing gastrointestinal upset.

Ground rose hips can be easily added to your dog’s meals at a dose of 1/2 to 1 teaspoon per cup of food.

6. Ginger

Ginger is a powerful root that supports respiratory health and soothes irritation caused by kennel cough. It’s particularly effective for calming the airways and supporting the immune system.

Use fresh ginger by mincing or grating the root, then mix it into your dog’s food. Dosage recommendations include 1/4 teaspoon for miniature breeds, 1/2 teaspoon for dogs under 35 pounds, and 3/4 teaspoon for larger dogs. Always start with small amounts to ensure your dog tolerates it well.

7. Immune Support Tea

A warm herbal tea can provide extra immune support and comfort for dogs recovering from kennel cough.

Combine these immune support ingredients:

• 4 tablespoons ground rose hips for vitamin C.
• 4 tablespoons dried echinacea for immune enhancement.
• 1 to 2 teaspoons fresh grated ginger for respiratory relief.
• 4 tablespoons dried chamomile for calming properties.

Steep these ingredients in boiling water for 10 minutes, then let the tea cool to room temperature. Add 1 to 2 teaspoons of the tea (including the herbs) to meals for small dogs and 2 to 4 tablespoons for larger dogs. This gentle remedy is safe for dogs of all ages, including puppies over 10 weeks and seniors.

The Risks Of Conventional Kennel Cough Treatments

While antibiotics are commonly prescribed for kennel cough, they’re often unnecessary since the condition is usually caused by a virus, not bacteria. Antibiotics won’t address viral infections, and their overuse can destroy beneficial gut bacteria, weakening your dog’s immune system and prolonging recovery.

Instead of defaulting to antibiotics, focus on natural remedies and immune support to help your dog recover. Only consider antibiotics if your vet identifies a secondary bacterial infection, and even then, weigh the risks and benefits carefully to avoid long-term harm to gut health.

Over-the-counter cough medicines may seem like a quick fix, but many contain harmful ingredients that can endanger your dog’s health. Ingredients like dextromethorphan (a common cough suppressant) and guaifenesin (a mucus thinner) may cause side effects like nausea, tremors, or an increased heart rate. Additionally, products containing xylitol, a sugar substitute, are toxic to dogs and can be deadly even in small amounts.

Dogs with liver disease, allergies, or cognitive issues are particularly vulnerable to adverse reactions. Human cough medicines often include other dangerous substances like acetaminophen, alcohol, and pseudoephedrine, all of which are toxic to dogs. Always avoid these medications and opt for natural, dog-safe alternatives instead.

Recovery And Precautions

Most healthy dogs will recover from kennel cough within a week, with symptoms like coughing and lethargy gradually subsiding. However, puppies, seniors, or dogs with compromised immune systems may take up to 1–2 months for a full recovery. During this time, it’s important to provide consistent care, focusing on hydration, rest, and natural remedies to support their recovery.

If symptoms worsen or persist beyond a few weeks, consult your vet to rule out complications like pneumonia or secondary infections. Early intervention can prevent kennel cough from escalating into more serious health issues, especially in at-risk dogs.

Because kennel cough is highly contagious, isolate your dog from others until they’re fully recovered to avoid spreading the infection. Keep your dog out of public spaces like parks, boarding facilities, and grooming salons, as these environments are hotspots for transmission.

Clean and disinfect surfaces, bedding, and toys your dog has come into contact with, as the bacteria or virus can linger on these items. Practice good hygiene by washing your hands after handling your dog, and ensure their environment is well-ventilated to minimize the risk of reinfection or spreading kennel cough to other pets.
