Upper Respiratory Infection In Dogs: Symptoms, Causes, & Treatments

2021-11-23  PetsCareTip

Upper respiratory infections in dogs can affect the bronchi, trachea, throat, and nasal cavities and are common, especially in dogs with compromised immune systems. Most dogs will have at least one upper respiratory infection in their lifetime.

These infections are often caused by bacteria and viruses that are quite contagious, which is why outbreaks are often seen in shelters, kennels, or places where lots of dogs are together in a close space. Upper respiratory infections are usually difficult to treat in canines, and relapses happen often.

The symptoms are typically similar to those of the common cold in humans, like sore throats, runny noses, coughs, etc. If you see signs of an upper respiratory infection in your dog, then it is important to get to the veterinarian right away to begin treatment quickly and prevent complications.

Here’s what you should know about the symptoms, causes, and treatments for upper respiratory infections in dogs.


Symptoms Of Upper Respiratory Infection In Dogs

Symptoms of upper respiratory infections in dogs can vary somewhat depending on the cause of the infection. However, canine nasal mite infection is rare in North America.

If you see the following symptoms in your dog, then get to the vet for a proper diagnosis and treatment:

  • Nasal discharge
  • Eye discharge
  • Fever
  • Itchy nose
  • Sneezing
  • Coughing, snorting, and wheezing
  • Gagging or retching
  • Dry nose
  • Drooling or foaming in the mouth
  • Ulcers of the mouth or nose
  • Loss of appetite
  • Weight loss
  • Dehydration
  • Lethargy
  • Exercise intolerance

Causes Of Upper Respiratory Infection In Dogs

There are several bacterial and viral causes of upper respiratory infections in dogs, and puppies, senior dogs, and dogs with compromised immune systems are more at risk.

Bordetella bronchiseptica is the most common bacteria that cause upper respiratory infections in dogs. This bacteria is related to Bordetella pertussis, which causes whooping cough in humans.

It can spread between dogs through coughing, clothing, or shared water bowls. It can lead to further secondary infections of E. coli, staph, and strep if untreated, and puppies may develop bronchopneumonia.

Upper respiratory infections in dogs can also be caused by viruses such as distemper, adenovirus, and withinfluenza, among others. Parainfluenza is the most common viral cause of upper respiratory infections in dogs. Any of these viruses can cause severe damage to the respiratory system and lead to upper airway disease.

In addition, sometimes parasites can cause upper respiratory infections in dogs. For example, pneumonyssoides caninum, more commonly known as the canine nasal mite, could cause a number of symptoms and leave dogs open to secondary infection. Usually these are similar to what humans experience when they have a cold.

Lung flukes, which live in pulmonary cysts in the lungs, may also cause upper respiratory infection symptoms, though they are very rare and transmitted by eating crayfish.

Treatments For Upper Respiratory Infection In Dogs

Treatment for upper respiratory infections in dogs often begins with prevention. Many diseases that cause top respiratory infection can be vaccinated against. Additionally, vaccinations may even help in reducing the symptoms of diseases that have no vaccination.

For example, dogs vaccinated against Bordetella have less severe symptoms when exposed to influenza. Some respiratory infections last between five and ten days and require no treatment, other than hydration and nourishment.

If an upper respiratory infection does occur, then antibiotics are often prescribed to help fight the disease. Doxycycline is a common drug that battles off Bordetella, for instance. Azithromycin might be used instead if doxycycline fails, as it is more powerful.

Veterinarians may also prescribe nose drops, rest, and lots of water to help dogs recover. In extreme cases, intravenous fluids and nutritional supplements may be provided.

During the infection, dogs should stay away from other animals to avoid spreading the disease.
