Canine Infectious Diseases

Canine Distemper

  • Caused by a virus related to measles
  • Affects respiratory, gastrointestinal and central nervous systems
  • Transmission: Highly contagious, transmitted via airborne droplets from infected dogs
  • Signs: Fever, runny nose, watery eyes, may progress to twitching muscles, paralysis, seizures
  • Treatment: Fluid therapy, plus antibiotics for secondary bacterial infections
  • Prognosis: Potentially fatal
  • Vaccination: Recommended for all dogs. North Mankato Animal Hospital requires this vaccine for dogs that will be in hospital/daycare/or here for surgery

Infectious Canine Hepatitis (Canine Adenovirus-1):

  • Viral disease that can damage the liver, kidneys, spleen, and lungs
  • Recovered dogs continue to shed virus in urine for at least 6 months
  • Transmission: Transmitted by ingested of urine, feces, or saliva of infected dogs
  • Signs: Fever, thirst, runny nose and eyes, vomiting, bleeding, respiratory disease
  • Treatment: Fluid therapy and antibiotics. Blood transfusions may be necessary
  • Prognosis: Mortality rate is highest in very young dogs
  • Vaccination: Recommended for all dogs. North Mankato Animal Hospital requires this vaccine for dogs that will be in hospital/daycare/or here for surgery

Canine Parvovirus:

  • Disease of the gastrointestinal tract. Puppies are most at risk
  • Resistant to many disinfectants
  • Transmission: Transmitted by contact with infected dogs or their feces
  • Signs: Bloody diarrhea, fever, lethargy. Some dogs may show no signs
  • Treatment: Fluid therapy, antibiotics and supportive care
  • Prognosis: Most dogs recover with appropriate care
  • Vaccination: Recommended for all dogs. North Mankato Animal Hospital requires this vaccine for dogs that will be in hospital/daycare/or here for surgery

Rabies:

  • Acute viral disease that can affect any mammal
  • Transmission: Almost always transmitted via the bite of a rabid animal (often a skunk, raccoon or bat)
  • Signs: Sudden, significant change in behavior (irritability, aggression, fear), unexplained paralysis
  • Treatment: None. Any unvaccinated animal exposed to rabies should be euthanized or strictly isolated immediately
  • Prognosis: Always fatal once clinical signs appear
  • Vaccination: Required for all dogs

Bordetella Bronchiseptica and Canine Parainfluenza Virus:

  • Often the primary bacteria contributing to infectious tracheobronchitis, an inflammation of the upper airways commonly called kennel cough
  • Transmission: Highly contagious, transmitted via airborne droplets from infected dogs
  • Signs: Harsh, dry cough, often followed by retching and gagging
  • Treatment: Supportive care and cough suppressants
  • Prognosis: Can lead to fatal bronchopneumonia in puppies or chronic bronchitis in elderly dogs
  • Vaccination: Recommended for dogs in close confinement, such as boarding, dog park, groomer. North Mankato Animal Hospital requires this vaccine for dogs that will be in hospital/daycare/or here for surgery

Leptospirosis:

  • Bacterial disease that can cause disease in the liver, kidneys, and other organs
  • Transmission: Transmitted through contact with an infected animal’s urine
  • Signs: Nonspecific early signs include: fever, lethargy, loss of appetite, joint, and muscle pain
  • Treatment: Fluid therapy and antibiotics
  • Prognosis: Acute renal failure occurs in 80% to 90% of dogs with clinically significant disease
  • Vaccination: Recommended for dogs older than 12 weeks of age where disease is prevalent

Lyme Disease:

  • Acquired from infected ticks by both dogs and humans
  • Lyme disease bacteria (Borrelia burgdorferi) damage joints, kidneys, and other tissues
  • Transmission: Transmitted by the bite of an infected tick
  • Signs: Lameness, fever, lack of appetite, lethargy
  • Treatment: Antibiotics
  • Prognosis: Infection can persist
  • Prevention: Vaccination prior to tick season in areas where disease is present, regular topical tick control (Frontline) and the avoidance of ticks
