How to Tell If Dog Has Fever Without Thermometer

As dog owners, we strive to provide the best care for our beloved four-legged companions. Just like humans, dogs can experience a range of health issues, including fever. Fever in dogs is a common concern for pet owners, and understanding its causes, symptoms, and treatment is crucial to ensure the well-being of our furry friends. In this article, we will explore everything you need to know about fever in dogs.

What is a Normal Temperature for a Dog?

In dogs, a normal body temperature ranges between 99.5°F and 102.5°F (37.5°C to 39.2°C). When a dog's body temperature rises above this range, it indicates the presence of a fever.

How to Take Your Dog's Temperature with a Thermometer?

There are two types of thermometers commonly used for measuring a dog's temperature: rectal and ear thermometers. 

Rectal thermometers are more accurate, but ear thermometers can be a less invasive option for dogs who are uncomfortable with rectal insertion. 

Rectal Thermometers

• Gather the necessary supplies, including a lubricant (such as petroleum jelly or water-based lubricant), disposable gloves, and alcohol wipes or soapy water for cleaning the thermometer.
• Create a Calm Environment: Find a quiet and comfortable space where your dog can relax. It's important to create a calm atmosphere to minimize stress for both you and your dog.
• Apply a small amount of lubricant to the tip of the thermometer. This helps with smooth insertion and reduces discomfort for your dog.
• For a rectal thermometer, gently lift your dog's tail and locate the anus. Carefully insert the thermometer about 1 inch into the rectum. Be gentle and avoid causing any discomfort or injury to your dog.
• Once the thermometer is inserted, hold it in place and ensure it is secure. Keep it in position for the recommended time as indicated by the thermometer's instructions or your veterinarian's guidance. This usually takes about 1-2 minutes.

• Check the display or reading on the thermometer to determine your dog's temperature.
• Clean the thermometer with alcohol wipes or soapy water and dry it thoroughly before storing it. Dispose of the gloves used during the process and wash your hands thoroughly.

Ear Thermometers

• Select a digital ear thermometer designed specifically for pets. These thermometers have a longer probe suitable for dogs' ear canals and provide accurate readings.
• Apply a small amount of water-based lubricant or petroleum jelly to the tip of the thermometer's probe. This helps with easy insertion and ensures a more comfortable experience for your dog.
• Gently lift your dog's ear and pull it slightly upward and outward to straighten the ear canal. Carefully and gently insert the thermometer probe into the ear canal. Be cautious not to insert it too far or apply excessive pressure, as it may cause discomfort or injury.
• Remove and Read the Temperature: Once the thermometer has completed the reading, gently remove it from your dog's ear. Take note of the temperature displayed on the thermometer's screen.

How to Tell If Dog Has Fever Without Thermometer?

While a thermometer is the most accurate way to determine if your dog has a fever, if you don't have one around or don't know how to use one, there are a few signs you can look for to assess if your dog has a fever.

• Elevated body temperature: Place your hand on your dog's skin, particularly its ears, paws, or belly. If they feel unusually warm or hot to the touch, it could be a sign of fever.
• Lethargy: A fever can make dogs feel tired and lethargic. If your dog is unusually sluggish or lacking energy, it may indicate a fever.
• Shivering or trembling: In some cases, dogs with a fever may experience shivering or trembling as their body attempts to regulate its temperature.
• Panting or rapid breathing: Fever can cause dogs to pant excessively or breathe rapidly as they try to cool down. Monitor their breathing patterns for any significant changes.
• Coughing or sneezing: If the fever is due to a respiratory infection, coughing and sneezing may be present.
• Runny nose 
• Warm ears and/or nose 
• Red eyes

What Causes Fever in Dogs?

1. Infections

Bacterial, viral, and fungal infections can trigger fever in dogs. Common infections include respiratory infections, urinary tract infections, tick-borne diseases, and parvovirus.

2. Inflammation

Inflammatory conditions such as pancreatitis, arthritis, and certain autoimmune disorders can cause fever.

3. Immune system response

Dogs may develop a fever as a response to vaccination, as their immune system mounts a defense against the introduced antigen.

4. Heatstroke

Exposure to excessive heat or being trapped in a hot environment can lead to heatstroke, resulting in an elevated body temperature.

5. Medications or vaccinations

Some medications and vaccinations may cause a mild fever as a side effect. This is generally temporary and should resolve on its own.

There are times when the cause of dog fever cannot be readily determined; this is called "fever of unknown origin," or FUO. The most likely causes for dog fever of unknown origin are disorders of the immune system, bone marrow problems, undiagnosed infections, and cancer.

How to Break Dogs Fever?

If you suspect your dog has a fever, you can do a thorough physical examination and diagnostic tests, such as blood work and urinalysis, may be conducted to identify the underlying cause.

If the fever is caused by an infection, the veterinarian may prescribe antibiotics or antiviral medication to address the underlying issue.

Cooling measures like cool water baths or fans may be employed for dogs experiencing heatstroke or high fevers. However, it is crucial to follow your veterinarian's instructions to avoid overcooling.

Home Remedies for Dog Fever

If your dog's fever is mild and your veterinarian approves, you can help cool them down by applying a cool, damp towel to their paws, groin, and armpit areas. Continue to monitor his temperature, and when it drops below 100, you can stop applying the water. Avoid using ice packs or extremely cold water, as they can be too harsh and may cause discomfort. 

Please try to keep them hydrated by letting them drink small amounts of water on a regular basis, but don't force it, you can also try adding low sodium chicken broth or water to make it more enticing.

Regularly check your dog's temperature using a rectal thermometer. This will help you monitor their progress and determine if their fever is improving or worsening. 

When to Bring Your Dog to the Vet?

If your dog is experiencing fever symptoms in addition to serious symptoms such as

• Difficulty breathing
• Severe pain
• Uncontrolled bleeding
• Seizures
• Persistent vomiting/diarrhea
• Difficulty urinating
• Blue gums
• Blood in feces

Or due to ingestion of chemicals, medications, or human foods that are toxic to dogs (e.g., chocolate, onions, grapes, raisins) Contact your veterinarian immediately!

FAQs

Can a Dog's Fever Go Away on Its Own?

In some cases, a dog's fever may resolve on its own, especially if it is mild and transient, such as a mild infection or vaccination cause dog fever.

Can Allergies Cause Fever in Dogs?

While allergies themselves do not directly cause fever, it is possible for a dog to experience a mild increase in body temperature due to the inflammatory response triggered by the allergy. This increase in body temperature, if present, is generally mild and transient.

Can I Give My Dog Aspirin for Fever?

It is not recommended to give your dog aspirin or any over-the-counter human medications without consulting a veterinarian first. Aspirin is a non-steroidal anti-inflammatory drug (NSAID) that can help reduce inflammation and relieve pain in humans. However, dogs can be more sensitive to the side effects of aspirin, including gastrointestinal irritation, ulcers, and potentially life-threatening complications such as bleeding disorders.

Why is the Dog Not Eating or Drinking with a Fever?

Some illnesses or infections can cause gastrointestinal symptoms such as nausea, vomiting, or diarrhea. These symptoms can further contribute to a dog's reluctance to eat or drink.

Can I Tell If My Dog Has a Fever Through Touch?

While you may be able to detect if your dog feels warm or has an elevated body temperature through touch, it is challenging to accurately determine the presence of a fever without using a thermometer. Dogs have different normal body temperatures compared to humans, and their fur can make it difficult to accurately assess their temperature by touch alone.
