Whether you’re walking your dog on a scorching summer day or braving icy winter temps, knowing your pup’s normal body temperature can help you keep him safe. Here’s the quick guide every dog parent should know.
What’s a Normal Dog Temperature?
A healthy dog’s internal temperature typically ranges from 99.5° to 102.5°F.
This range is slightly higher than humans — so your pup may feel warm to the touch even when he’s perfectly fine.
When Your Dog Is Too Hot
If your dog’s temperature climbs above 103°F, that means he’s too hot and he may have a fever or be at risk for heatstroke, which can be fatal without fast action.
Heatstroke Signs in Dogs:
- Heavy panting
- Hot skin
- Vomiting
- Wobbling or lack of coordination
- Collapse
- Seizures
- Dark red gums
- Loss of consciousness
Possible Fever Signs:
- Warm, dry nose
- Lethargy
- Low energy
- Loss of appetite
- Warm ears
- Shivering
- Vomiting or diarrhea
- Coughing or nasal discharge
👉 If you notice these symptoms, get your dog to the vet immediately.
When Your Dog Is Too Cold
A temperature around 98–99°F may indicate hypothermia, a dangerous drop in body temperature requiring urgent medical care.
Hypothermia Symptoms:
- Cold ears, paws, or nose
- Shivering
- Stiff muscles
- Pale gums
- Extreme lethargy
- Weakness
- Collapse
- Slow or irregular heartbeat
- Slow breathing
- Confusion
How to Check Your Dog’s Temperature
You can use a pet thermometer to confirm your dog’s internal temperature. Human thermometers can work in a pinch, but dog-specific ones are more sanitary and often more accurate.
Types of Pet Thermometers:
- Rectal (most accurate)
- Ear (next best)
- Non-contact infrared (least accurate, measures surface temp only)
How to Use Each Type
Rectal Thermometer (most accurate)
- Have your dog lie down or ask someone to gently hold him still.
- Apply pet-safe lubricant to the thermometer.
- Insert only 1–3 inches—never force it.
- Wait for the reading.
- Clean the thermometer thoroughly afterward.
Ear Thermometer
- Hold your dog’s head steady.
- Insert the thermometer gently into the ear while supporting the ear base.
- Wait for the reading.
Non-Contact Thermometer
Just point it at your dog’s belly or ear and read the external temperature.
What to Do If Your Dog Is Too Hot or Too Cold
If he’s too hot:
- Offer cool drinking water
- Apply cool (not ice-cold) water to his body
- Use a fan
- Recheck temperature to avoid overcooling
- Get veterinary help ASAP
If he’s too cold:
- Wrap him in a warm towel or blanket
- Dry wet fur
- Move him indoors immediately
- Seek veterinary care
Why Knowing Your Dog’s Temperature Matters
Monitoring your dog’s body temperature helps you catch emergencies early, prevent heatstroke or hypothermia, and know exactly when it’s time to get veterinary help.
A few seconds with a thermometer can save your dog’s life.
