Hypothermia in Dogs: What It Is, What to Watch For, and What to Do

Cold weather can be more dangerous for dogs than many owners realize. Hypothermia doesn’t only happen in extreme conditions. It can occur during winter walks, outdoor play, or even short periods outside if the conditions are right.

Knowing the signs and what to do can make a serious difference.

What Is Hypothermia in Dogs?

Hypothermia happens when a dog’s body temperature drops below normal and they can no longer maintain enough heat to function properly.

A dog’s normal body temperature is roughly 101–102.5°F. When it drops too low, the body starts to slow down, which can quickly become dangerous if not addressed.

Dogs most at risk include:

• Puppies and senior dogs

• Small or short-haired dogs

• Dogs that are wet, tired, or exposed to wind

• Dogs left outside too long in cold weather

What Does Hypothermia Look Like?

Early signs can be easy to miss, especially if you assume your dog is “just cold.”

Common symptoms include:

• Shivering or trembling

• Lethargy or weakness

• Slow movement or reluctance to walk

• Cold ears, paws, or tail

• Stiff muscles

As hypothermia becomes more severe, signs may include:

• Slowed breathing or heart rate

• Confusion or lack of awareness

• Pale gums

• Collapse or loss of consciousness

If symptoms progress, hypothermia becomes a medical emergency.

How to Check for Hypothermia

If you suspect your dog may be too cold:

1. Feel their body — especially ears, paws, belly, and chest. If they feel unusually cold or stiff, that’s a red flag.

2. Watch their behavior — sluggishness, hesitation to move, or unresponsiveness are concerning signs.

3. Check temperature (if possible) — a rectal thermometer can give the most accurate reading. Anything significantly below normal warrants immediate action.

If you’re unsure, it’s always safer to act early rather than wait.

What to Do If You Think Your Dog Has Hypothermia

If you believe your dog is hypothermic:

1. Move them to a warm, dry area immediately — Get them indoors or into shelter away from wind and cold.

2. Dry them off if they’re wet — Moisture increases heat loss dramatically.

3. Warm them gradually — Use blankets, towels, or your body heat. Avoid hot water, heating pads, or rapid warming, which can cause complications.

4. Offer warm (not hot) fluids if they’re alert — Only if your dog is conscious and able to swallow safely.

5. Contact your veterinarian — Moderate to severe hypothermia requires professional care, even if your dog seems to improve.

Prevention Is Key

The best way to handle hypothermia is to prevent it:

• Limit outdoor time in cold weather

• Use coats for short-haired or small dogs

• Dry dogs thoroughly after snow or rain

• Watch for signs of fatigue or slowing down

• Don’t assume excitement means they aren’t cold

Let's Keep our Dogs Safe and Warm this Cold Winter

Dogs don’t always show discomfort the way we expect them to. Being proactive, observant, and prepared during cold weather can keep winter outings safe and enjoyable.

If you ever feel unsure, trust your instincts, it’s better to warm your dog up early than risk waiting too long.
