As a dog owner, you know how important it is to keep your furry friend healthy and happy. But what happens when your dog seems “off”? Could they have a fever? Just like humans, dogs can develop fevers when their bodies are fighting infections or illnesses. Understanding the signs and symptoms can help you take action quickly to ensure your pet gets the care they need.

⚠️ What to Watch For

Unlike humans, dogs can’t tell us when they’re not feeling well. That’s why it’s so important to recognize the subtle signs of a fever. A dog’s normal body temperature ranges between 101°F and 102.5°F. A temperature above 103°F is considered a fever, and anything over 106°F is a medical emergency.

Here are five key signs and symptoms that might indicate your dog has a fever:

  • Lethargy or lack of energy
  • Warm ears and nose
  • Shivering or trembling
  • Loss of appetite
  • Red or glassy eyes

These symptoms can also overlap with other conditions, so it’s important to monitor your dog closely and look for patterns in their behavior and physical state.

🔍 Possible Causes

Fever in dogs can be triggered by a variety of factors. Some of the most common causes include:

  • Infections: Bacterial, viral, or fungal infections can cause your dog’s body to heat up as it fights off the illness. These infections can occur anywhere in the body, such as the skin, lungs, or urinary tract.
  • Inflammatory conditions: Autoimmune diseases or other inflammatory issues can result in a fever.
  • Toxins: If your dog ingests something toxic, such as certain plants, medications, or foods, their body may react with a fever.
  • Vaccinations: Some dogs may experience a mild fever as a temporary side effect after receiving vaccines.
  • Unknown origins: Sometimes, a fever’s cause cannot be pinpointed, which is referred to as a fever of unknown origin (FUO).

Knowing what might be behind your dog’s fever can help guide the next steps, whether that’s monitoring them at home or seeking veterinary care.

✅ What You Can Do at Home

If you suspect your dog has a fever, there are a few steps you can take to help them feel more comfortable while determining if professional care is needed.

  • Take their temperature: Use a digital rectal thermometer designed for pets to get an accurate reading. Avoid relying on touch alone to gauge temperature, as it’s not reliable.
  • Keep them hydrated: Offer fresh water to prevent dehydration, which can worsen their condition.
  • Cool them down: Place a cool, damp cloth on their paws, ears, or belly to help bring their temperature down. Avoid ice-cold water, as this can shock their system.
  • Monitor their symptoms: Keep an eye on changes in behavior, appetite, or energy levels to assess if their condition is improving or worsening.

Never give your dog human medications like ibuprofen or acetaminophen, as these can be toxic to dogs. If you’re unsure what to do, consult a veterinarian for guidance.

💡 When to Call a Vet

While some fevers can resolve on their own, others require prompt medical attention. You should contact your vet if:

  • Your dog’s temperature exceeds 103°F and doesn’t come down within 24 hours
  • They show severe symptoms such as vomiting, diarrhea, or difficulty breathing
  • The fever reaches 106°F or higher, as this is a life-threatening emergency
  • You suspect an infection, toxin exposure, or another serious cause

According to VCA Animal Hospitals, untreated high fevers can lead to serious complications like organ damage (source). If you’re ever in doubt, it’s better to err on the side of caution and consult a vet.

FAQs

Q: How can I check if my dog has a fever without a thermometer?
A: While using a thermometer is the most accurate method, you can look for signs like warm ears or nose, lethargy, and shivering. However, these signs are not definitive, and a thermometer is recommended for confirmation.

Q: Can a dog’s fever go away on its own?
A: Mild fevers may resolve naturally as your dog’s body fights off the underlying cause. However, if the fever persists or worsens, it’s important to seek veterinary care.
