Dog/Canine Fever Treatment

Definition
Fever is defined as an elevated body temperature (>103°F |>39.5°C}) due to an altered hypothalamic set point.

Young patients are more likely to have infectious causes. Middle-aged patients are more likely to have noninfectious inflammatory diseases. Older patients are more likely to have neoplastic causes.

Temperatures >106°F (>41.1°C) may cause multiple organ dysfunction, disseminated intravascular coagulation and death.

41.1°C)

Antipyretic agents (e.g., nonsteroidal anti-inflammatory [NSAIDs), to be given only when the patient is fully hydrated) may be considered for fevers >106°F (>41.1°C) that do not respond to fluids and cooling.

Chronic Treatment

Broad-spectrum antibiotic therapy may be initiated. Commonly used empiric antibiotics include amoxicillin-clavulanate 10-20 mg/kg PO q 8-12h and enrofloxacin 5-10 mg/kg (dog), 5 mg/kg (cat) PO q 24h;
5-15 mg/kg PO q 8-12h; if tick-borne disease is suspected, doxycycline 10 mg/kg PO q 24h or 5 mg/kg PO q 12h.

The use of NSAIDs in combination with glucocorticoids should be avoided.
