Parainfluenza in Dogs

When dogs develop a persistent cough, many pet owners assume it’s a minor issue. However, a cough can sometimes be a sign of a contagious respiratory infection, such as parainfluenza in dogs. This virus spreads quickly among dogs, particularly in areas where they interact closely, like dog parks, kennels, and grooming facilities. While parainfluenza is not the same as canine influenza, it is a leading cause of kennel cough and can significantly impact your dog’s health. If your dog is showing symptoms of a respiratory illness, Sahara Pines Animal Hospital in Las Vegas, NV, can provide expert care. Call (702) 876-7580 or book an appointment online today!

What is Parainfluenza in Dogs?

Canine parainfluenza is a highly contagious respiratory virus that affects dogs of all ages. It is a major contributor to kennel cough, a broader term used to describe various infections that cause a dry, hacking cough. The parainfluenza virus in dogs targets the respiratory system, leading to inflammation in the airways and increased mucus production.

How Parainfluenza Spreads

Parainfluenza in dogs spreads through direct contact, airborne particles, and contaminated surfaces. The virus can survive on objects like water bowls, toys, and bedding, making shared environments a hotspot for infection. Dogs most at risk include those in boarding facilities, shelters, daycare centers, and dog parks. Once infected, a dog can spread the virus even before showing symptoms. The incubation period is typically 3 to 10 days, during which time an infected dog can unknowingly pass the virus to others.

Symptoms of Parainfluenza in Dogs

Dogs with parainfluenza often exhibit symptoms similar to those of other respiratory infections. While some cases are mild, others can become more severe, particularly in puppies, senior dogs, and those with weakened immune systems. Common signs of infection include: 

• Persistent, dry cough
• A runny nose with clear or cloudy discharge 
• Frequent sneezing
• Watery eyes
• Lethargy
• Loss of appetite
• Fever

If your dog is experiencing these symptoms, contact Sahara Pines Animal Hospital at (702) 876-7580 to schedule an exam.

Is Parainfluenza in Dogs Serious?

Most healthy adult dogs recover from parainfluenza within 10 to 14 days without complications. However, some cases can progress into secondary infections, pneumonia, or chronic respiratory issues. Dogs with underlying health conditions, such as heart disease or compromised immune systems, are at greater risk for severe illness. Puppies and older dogs are also more susceptible to prolonged symptoms and complications. Since parainfluenza is highly contagious, prompt veterinary attention helps reduce the spread and ensures your dog receives the right care.

How Vets Diagnose Parainfluenza in Dogs

Veterinarians diagnose parainfluenza in dogs based on clinical signs, medical history, and diagnostic tests. If your dog has been exposed to other dogs or recently boarded, your vet may suspect a contagious respiratory infection.

Diagnostic Methods

• Physical examination – Your vet will listen to your dog’s lungs and assess symptoms.
• PCR testing – A nasal or throat swab can confirm the presence of parainfluenza.
• X-rays – Chest X-rays help rule out pneumonia or other lung conditions.
• Blood tests – These can identify secondary infections or inflammation.

Treatment for Parainfluenza in Dogs

There is no specific antiviral treatment for parainfluenza in dogs, but supportive care helps manage symptoms and promotes recovery.

Veterinary Treatment Options

• Cough suppressants – Medications can help relieve persistent coughing.
• Anti-inflammatory drugs – These reduce airway swelling and discomfort.
• Antibiotics – If a secondary bacterial infection develops, antibiotics may be necessary.
• Fluids – Hydration is essential for recovery, and IV fluids may be given in severe cases.

At-Home Care Recommendations

• Rest and isolation – Keep your dog calm and away from other pets to prevent spreading the virus.
• Humidifiers – Moist air can help soothe irritated airways.
• Proper hydration – Encourage drinking water to thin mucus and prevent dehydration.
• Soft food – If your dog has a sore throat, softer meals may be easier to eat.

If symptoms worsen or persist beyond two weeks, a follow-up exam is recommended to rule out complications.

What You Can Do to Prevent Parainfluenza in Dogs

While parainfluenza in dogs is contagious, several preventive measures can help reduce the risk of infection.

Vaccination

The parainfluenza vaccine is often included in combination vaccines, such as the Bordetella or DHPP vaccine. While this vaccine does not provide 100% immunity, it helps lessen the severity of symptoms if exposure occurs. Dogs that frequently visit boarding facilities, groomers, or dog parks should be vaccinated annually to lower their risk.

Minimizing Exposure

• Avoid contact with dogs showing signs of illness.
• Clean and disinfect shared items like bowls, leashes, and toys.
• Choose reputable boarding facilities that require vaccinations.
• Strengthen your dog’s immune system with a healthy diet and regular exercise.

If you’re unsure whether your dog is up to date on vaccines, schedule a visit with Sahara Pines Animal Hospital by calling (702) 876-7580.
