Understanding DOG Fever

What Is a Dog Fever?

A fever in dogs, known as pyrexia, is an elevation of the body temperature above the normal range. While the typical body temperature for dogs varies slightly depending on the breed, it usually falls between 100.5°F to 102.5°F (38°C to 39.2°C). A fever occurs when the body’s internal temperature regulation system is disrupted, often due to an underlying health issue.

Why Do Dogs Get Fevers?

Fever is not an illness itself but rather a symptom of an underlying problem.

  • Infections: Bacterial, viral, or fungal infections can trigger a fever as the body’s defense mechanism.

  • Inflammation: Inflammatory conditions like arthritis or autoimmune disorders can lead to a fever.

  • Heatstroke: Exposure to high temperatures and heatstroke can result in a dangerously elevated body temperature.

  • Reaction to Medications or Vaccines: Some dogs may develop a fever as a reaction to medications or vaccinations.
