How to Take Your Dog's Temperature Safely and Accurately

It can be worrying when your beloved dog is unwell and not acting like themselves. If your dog is off their food or reluctant to go for their usual walk, it helps to check whether they have a fever by taking their temperature. This guide explains how to do so safely using the best methods available in 2025.

Understanding Your Dog's Normal Temperature Range

A healthy dog's normal body temperature generally ranges between 100.5#60F and 102.5#60F (approximately 38#60C to 39#60C). While many owners might feel their dog%s ears or nose to detect a fever, these are not accurate indicators of core body temperature. The most reliable method is to use a rectal thermometer, which measures your dog's internal temperature directly. Ear thermometers provide an alternative but tend to be less accurate and require careful use.

How to Take a Dog's Temperature Using a Rectal Thermometer

The rectal method remains the gold standard for an accurate temperature reading. Here's how to do it step by step:

Step 1: Prepare the Thermometer

• Use a high-quality digital rectal thermometer designed for pets.
• Apply a small amount of lubricant like petroleum jelly to the tip to ease insertion and reduce discomfort.

Step 2: Position and Restrain Your Dog

• Have your dog in a comfortable position, either standing or lying on a flat, non-slip surface.
• If possible, enlist the help of someone else to gently hold your dog%s head and shoulders to keep them calm.
• Speak calmly and reassure your dog throughout the process.

Step 3: Insert the Thermometer

• Gently lift your dog%s tail.
• Slowly and carefully insert the lubricated tip of the thermometer about 1 to 2 centimetres (roughly one inch).
• Hold it steady until the thermometer signals it has finished reading (usually a beep for digital thermometers).

Step 4: Read and Record the Temperature

• Remove the thermometer gently and note the temperature immediately.
• A reading above 103#60F (39.4#60C) may indicate a fever; below 99#60F (37.2#60C) might suggest hypothermia.
• Clean the thermometer with antiseptic wipes after use before storing.

Step 5: Reward Your Dog

Offer treats and praise to make the experience positive, helping your dog stay calm if you need to take their temperature again in the future.

Using an Ear Thermometer: Convenience with Caution

Ear thermometers are less invasive and can be easier, especially for dogs that dislike rectal checks. However, they are generally less accurate because of factors such as ear wax, infections, or improper positioning. For accuracy, place the thermometer gently and deeply enough into the ear canal to measure heat waves near the eardrum.

Ask your vet to demonstrate the ear thermometer technique before attempting it yourself. Avoid using ear thermometers if your dog has an ear infection or is uncooperative, as this could cause discomfort or injury.

Comparing ear thermometer readings with rectal measurements can help you learn the correct placement and assess reliability. A normal ear temperature typically ranges between 100#60F and 103#60F.

When to Call Your Vet

If your dog's temperature reaches 104#60F (40#60C) or higher, or falls below 99#60F (37.2#60C), seek veterinary advice immediately. Other signs such as lethargy, rapid breathing, shivering, vomiting, diarrhoea, or persistent loss of appetite alongside a raised temperature also warrant prompt professional attention.

Common Questions

What is the normal temperature range for dogs?

Quick Answer: A typical healthy dog%s temperature ranges from 100.5#60F to 102.5#60F (38#60C to 39#60C).

Dogs% temperatures naturally vary slightly based on breed, age, and activity. A reading above 103#60F usually indicates fever and possible illness, while a temperature below 99#60F can indicate hypothermia.

Are ear thermometers accurate for dogs?

Quick Answer: Ear thermometers offer convenient temperature taking but are generally less accurate than rectal thermometers.

The accuracy depends on proper technique and the dog%s ear condition. Wax blockages or infections can lead to inaccurate readings. For precise diagnosis, rectal thermometers remain preferred by vets.

Signs of a fever in dogs and when should I call the vet?

Quick Answer: Fever signs include lethargy, shivering, rapid breathing, warm dry nose, and loss of appetite. Call a vet if the temperature exceeds 104#60F or symptoms worsen.

Other symptoms like vomiting, diarrhoea, or neurological signs alongside fever require urgent veterinary assessment. Monitor your dog carefully and seek help if fever lasts over 24 hours or is very high.

Conclusion

Knowing how to take your dog's temperature is vital for timely health care decisions. While rectal thermometers deliver the most accurate results, ear thermometers can be useful with precautions. Always have a good-quality thermometer in your dog's first aid kit and consult your vet if you suspect a fever or if your dog shows worrying symptoms. Responsible pet ownership means staying vigilant and responding promptly to your dog's health needs.
