Dog Fever: Symptoms, Causes and Treatment

Fever in dogs is usually a sign that the body is fighting an infection or inflammation. A normal body temperature for dogs ranges between 101°F and 102.5°F. When the temperature rises above this range, it indicates fever and may require veterinary evaluation depending on the cause.

What Causes Fever in Dogs?

Fever occurs when the immune system responds to infection, inflammation, or toxins. Several medical conditions can cause elevated body temperature in dogs.

• Bacterial infections
• Viral infections such as parvovirus or distemper
• Tick-borne diseases
• Urinary tract infections
• Inflammatory diseases
• Reaction to toxins
• Post-vaccination reactions

Symptoms of Fever in Dogs

Dogs with fever often show behavioral and physical changes that indicate illness.

• Lethargy or weakness
• Loss of appetite
• Warm ears and nose
• Shivering
• Vomiting or diarrhea
• Decreased activity

How to Check if Your Dog Has a Fever

The most accurate way to measure a dog's temperature is using a digital rectal thermometer. Temperatures above 103°F usually indicate fever.

When Should You Be Concerned?

Fever can sometimes resolve on its own, but persistent high temperature may indicate a serious condition.

• Temperature above 103°F
• Fever lasting more than 24 hours
• Severe lethargy
• Vomiting or diarrhea with fever
• Fever in puppies

Diagnosis by a Veterinarian

Veterinarians may perform several diagnostic tests to determine the cause of fever.

• Blood tests
• Urine analysis
• X-rays
• Ultrasound
• Tick disease screening

Treatment Options

Treatment depends on the underlying cause of fever.

• Antibiotics for bacterial infections
• Anti-inflammatory medication
• Fluid therapy
• Supportive care

Home Care Tips

If your dog has mild fever but remains alert, supportive care may help.
