Parainfluenza in Dogs

What is the parainfluenza in dogs?

Parainfluenza is a highly contagious viral lung infection that can cause infectious tracheobronchitis, also known as 'kennel cough.'

While the respiratory symptoms of parainfluenza are similar to those seen in dogs with canine influenza, the viruses are very different and require different treatments and vaccinations.

Canine parainfluenza is commonly found in areas with dense dog populations, such as dog race tracks, shelters, and kennels.

Fortunately, there is a parainfluenza dog vaccine to prevent your pup from ever getting the infection.

What are the symptoms of parainfluenza in dogs?

The symptoms of canine parainfluenza virus infections are listed below. The severity or intensity of these symptoms may vary depending on the age of the infected dog and the host's immune system:

• Coughing - This can be either a dry cough or wet (can include blood)
• Low-grade fever
• Discharge from the nose - This can be mucus, pus or even blood
• Decreased energy
• Decreased appetite

Note that the virus itself can be a component of other canine respiratory diseases, most notably kennel cough, bordetella, and canine adenovirus-2.

What causes parainfluenza in dogs?

Parainfluenza is viral and transmitted via the air dogs breathe. As such, it is a very contagious disease, especially for dogs who live or spend time with other dogs.

The parainfluenza virus is related to canine distemper and shares respiratory symptoms, including a dry, hacking cough and inflammation of the larynx, bronchial tubes, and trachea. Puppies and older adult canines with compromised immune systems are at higher risk. Because of the thick secretions produced by throat irritation, toy breeds are also more susceptible to pneumonia.

After the infection has healed, the virus can still be picked up in the air for up to two weeks.

How is parainfluenza diagnosed?

The vet will require a detailed history from you. The parainfluenza virus is easily spread in boarding kennels, grooming salons, and other places where a large number of dogs congregate. It is critical to provide information about your pet's whereabouts within two to four weeks of the first symptoms appearing in your family pet.

A health history and vaccination history will be required. Any contact with other canines, regardless of the environment in which that contact occurred, could be part of the infective process, so provide as much detail as possible.

The veterinarian will perform a physical examination, as well has some diagnostics like blood tests, cultures, and testing of fluid and tissue samples. He may also need to use imaging techniques such as radiography (x-ray) to determine whether there are any masses or parasitic involvement. Once all of the testing results have been received and analyzed, a treatment plan will be developed and implemented.

How do you treat parainfluenza in dogs?

Because the virus is highly contagious to other canines, your vet is unlikely to recommend hospitalization unless the situation is dire. In lieu of hospitalization, your veterinarian may make management recommendations, which will most likely include:

• Recommendations for healthy eating, hygiene, and nursing care
• Recommendations for corrective action for any environmental factors suspected of being contributors
• Cough suppressants containing codeine derivatives should be used only for long-term, ineffective cough relief.
• Severe chronic cases may necessitate antibiotics such as cephalosporins, quinolones, chloramphenicol, and tetracycline; the appropriate antibiotic medication will most likely be chosen based on the results of the cultures taken and analyzed.
• Some treatment options may include bronchodilator pretreatment followed by aerosolization treatments.

Is there a vaccine for dog parainfluenza?

At Argyle Veterinary Hospital, we give dogs the DHPP (Distemper, Hepatitis, Parainfluenza, Parvovirus) vaccine between six to eight weeks of age. Then we give boosters between ten to 12 weeks old, 14 to16 weeks old, and 12 months to 16 months old. After that, it is highly recommended to schedule your dog's annual vaccinations and routine exam to protect them from parainfluenza and a host of other diseases too.
