Dog Fever Symptoms: How to Know If Your Pup Is Sick

As a pet parent, it’s important to be aware of the signs that indicate your dog may have a fever. While dogs can’t tell us when they’re feeling unwell, changes in their behavior and physical symptoms can signal that something is wrong. Here’s how to identify fever in dogs and what to do if your pup is sick.

What is a Normal Temperature for Dogs?

A healthy dog’s normal body temperature ranges between 101°F and 102.5°F. A temperature above 103°F is considered a fever, and anything above 106°F is a medical emergency that requires immediate veterinary attention.

Common Symptoms of Fever in Dogs

If your dog has a fever, you may notice several key symptoms, including:

• Warm or Hot Ears and Nose – While not always a definitive sign, a dog’s ears and nose may feel unusually warm.
• Lethargy and Weakness – A dog with a fever may lack energy and prefer to rest instead of engaging in normal activities.
• Shivering or Trembling – Fever can cause chills, leading to shivering or shaking.
• Loss of Appetite – If your dog refuses food or water, it could be a sign of fever or illness.
• Red or Glassy Eyes – Fever can cause the eyes to appear bloodshot or have an unusual shine.
• Panting and Rapid Breathing – Elevated body temperature can lead to excessive panting or labored breathing.
• Nasal Discharge or Coughing – If your dog has a fever due to an infection, you might notice nasal discharge or coughing.
• Vomiting or Diarrhea – Digestive issues can accompany fever and may indicate an underlying illness.

How to Check Your Dog’s Temperature

To confirm a fever, use a rectal thermometer designed for pets. Here’s how:

1. Lubricate the thermometer tip with petroleum jelly or water-based lubricant.
2. Gently insert it about 1 inch into your dog’s rectum.
3. Hold it in place for 30-60 seconds until you get a reading.
4. If the temperature is above 103°F, your dog has a fever.

What Causes Fever in Dogs?

Several factors can cause fever, including:

• Bacterial or Viral Infections – Common illnesses like kennel cough, urinary tract infections, or ear infections can cause fever.
• Inflammatory Conditions – Diseases such as autoimmune disorders or pancreatitis can trigger fever.
• Heatstroke – Overheating in hot weather can lead to dangerously high body temperatures.
• Ingestion of Toxins – Eating toxic substances like human medications, poisonous plants, or chemicals can cause fever.
• Unknown Causes (Fever of Unknown Origin) – Sometimes, no specific cause can be identified, and further veterinary testing is required.

What to Do If Your Dog Has a Fever?

If you suspect your dog has a fever:

• Provide Fresh Water – Keep your dog hydrated to prevent dehydration.
• Use Cool (Not Cold) Compresses – Apply a damp cloth to your dog’s paws, ears, and belly to help lower body temperature.
• Monitor Symptoms – Keep an eye on your dog’s behavior and check their temperature regularly.
• Avoid Giving Human Medications – Never give ibuprofen, aspirin, or acetaminophen, as they are toxic to dogs.
• Call Your Vet – If the fever is above 103°F or lasts more than 24 hours, consult your veterinarian for further advice.

When to Seek Emergency Veterinary Care

Take your dog to the vet immediately if they have:

• A fever of 106°F or higher
• Severe vomiting or diarrhea
• Difficulty breathing
• Seizures or unresponsiveness
• Signs of poisoning (e.g., drooling, tremors, sudden collapse)

Final Thoughts

Fever in dogs is often a sign of an underlying health issue, so it’s important to monitor your pup closely and seek veterinary care when needed. By recognizing the symptoms early and taking the right steps, you can help ensure your furry friend gets the care they need to recover quickly.
