What Is Upper Respiratory Tract Infection In Dogs?

Upper respiratory infections in dogs are usually a heterogeneous condition caused by several viruses and bacteria. Some of the upper airway diseases in dogs are infectious respiratory disease complex, kennel cough, laryngotracheitis, and infectious tracheobronchitis (ITB).

Infectious laryngotracheitis (ILT) is an uncommon, highly contagious, and acute infection caused by Canine Adenovirus type 2 (CAV-2). Infectious tracheobronchitis or kennel cough is a multifactorial, highly contagious disease that is caused due to acute or chronic inflammation of the trachea and bronchial airways.

In general, the term ‘Kennel cough’ is an umbrella term for any contagious condition centering on the lungs where one of the major clinical signs is ‘coughing’. ‘Infectious tracheobronchitis’ term suggests the site of the infection is the trachea (or ‘windpipe’) and bronchial tubes.

ITB is often a result of viral infection of the respiratory system. Typically, it is a mild, self-recovering infection that normally improves on its own. Sometimes, however, in weakened, debilitated, or aged dogs, it can progress to fatal bronchopneumonia (in puppies) and chronic bronchitis. The infection spreads quickly among vulnerable dogs housed in close detention, such as kennels, veterinary hospitals, grooming facilities, or rescue centers.

Symptoms Of Upper Respiratory Tract Infection In Dogs

Severe cases

  • Dogs try to clear their throat or spit up or gag, often mistaken as vomiting.
  • Bronchopneumonia
  • Tachypnea

  • Broad-spectrum antibiotics such as Amoxicillin, Cephalexin, Chloramphenicol, Clindamycin, Doxycycline, Gentamicin, Metronidazole, and Sulfadimethoxine
  • cough suppressants (Dextromethorphan, Butorphanol Benylin, Balminil, Delsym)

Causes And Prognosis For Upper Respiratory Tract Infection In Dogs

1. Causes:

Incubation period: 2–8 days (with a range of 2–14)

Transmission:

  • Suspended aerosol microdroplets of respiratory secretions.
  • The most common cause is Oronasal contact with other dogs or fomites (both porous and nonporous surfaces) and owners. Healthcare professionals (less common)

Bacteria

  • Mycoplasmas (Mycoplasma cynos)
  • Streptococcus Equi (subspecies zooepidemicus)
  • Aerobic coccobacillus (Bordetella bronchiseptica)

Canine Viruses

  • Adenovirus 2
  • Bocavirus
  • Coronavirus (pantropic strain)
  • Distemper virus
  • Hepacivirus
  • Herpesvirus
  • Influenza virus
  • Parainfluenza virus
  • Pneumovirus
  • Respiratory coronavirus
  • Reovirus

2. Morbidity:

  • Canine distemper virus/ Canine influenza virus infection symptoms start off with symptoms similar to Kennel cough
  • Signs vary from a slight fever and a loud cough to hemorrhagic viral pneumonia
  • Most viruses are cleared in 2 weeks; however, sometimes clinical symptoms may last for even weeks

3. Mortality:

Puppies have the highest mortality rate (usually it ranges < 5%)

  • Pneumonia (0.4%)
  • Unspecified disease or failure (0.4%)
  • Tracheal collapse (0.2%)
  • Laryngeal paralysis (0.1%)
  • Bronchitis (0.1%)

4. Diagnosis:

  • T Complete blood count (CBC), blood chemistry profile
  • Urinalysis
  • Electrolyte panel
  • Antigen test (enzyme immunoassay or EIA)

5. Prognosis:

It is really difficult to predict chances for recovery as the nature and extent of the disease vary greatly for each dog. In general, respiratory tract infections are rarely fatal and will usually be self-limiting. However, medications are typically given to check the condition from aggravating and to help your dog recover faster.
