Why Is My Dog's Nose Warm?

One common concern for dog owners is noticing when their dog’s nose feels warm or dry. We often hear that a cool, wet nose means a dog is healthy, so what does it mean when a nose feels warmer than usual? While a warm nose might cause concern, it’s not always a sign that something’s wrong.

Why a Dog’s Nose Changes Temperature

A dog’s nose naturally varies in temperature throughout the day. Some reasons for a warm or dry nose are entirely normal and can include:

Environmental Factors

Warm or dry air, sun exposure, or sitting close to a heater can temporarily warm up your dog’s nose.

Activity Level

After a nap, your dog’s nose may be warmer than usual, as their body temperature often rises slightly during sleep.

Dehydration

If your dog hasn’t had enough water, their nose may dry out a bit. Ensure they have plenty of fresh water, especially after exercise.

Age

Puppies and older dogs may experience more fluctuations in nose temperature due to their changing metabolisms and unique needs. Puppies tend to have warmer noses, while senior dogs may have drier noses, both of which are typically normal.

Breed

Certain breeds, especially brachycephalic (flat-faced) breeds like Bulldogs and Pugs, tend to have warmer, drier noses due to their anatomy and respiratory structure. Some breeds are also more prone to dry noses, especially in warmer climates.

Which Dog Breeds Are More Prone to Warm, Dry Noses?

The following dog breeds are some that may be more prone to warm, dry noses:

• Bulldogs
• Boxers
• Pugs
• Shih tzus
• Boston terriers
• Labrador retrievers
• Dachsunds
• Chow chows
• Chihuahuas
• Golden retrievers

When a Warm Nose Might Signal a Health Issue

While a warm nose is often harmless, there are instances when it can be a sign of an underlying health issue. Here are a few conditions to watch for:

Fever

Just like people, dogs can develop fevers when fighting off infections. If your dog’s warm nose is accompanied by lethargy, loss of appetite, or unusual behavior, it’s best to check their temperature or visit a vet.

How to Check if Your Dog Has a Fever

If your dog’s nose feels unusually warm and they’re showing other signs of illness, taking their temperature is the best way to confirm if they have a fever. A normal temperature for dogs ranges from 101°F to 102.5°F. Use a pet thermometer and place it gently in the rectum, or consult your vet for guidance on proper methods to check.

Sunburn

Dogs, especially those with light-colored or thin coats, can get sunburned on their noses and other exposed areas. If your dog’s nose is warm, red, or peeling, sunburn may be to blame. Consider using a dog-safe sunscreen if they spend a lot of time in the sun. Sunburn can appear differently on different dogs, so if you notice changes to your dog's nose, you may want to consult your vet.

Allergies

Dogs can have allergies that cause a warm, irritated nose. If your dog is also sneezing, has a runny nose, or seems itchy, allergies could be the culprit.

Symptoms of Allergies in Dogs

• Sneezing
• Warm, dry nose
• Swollen face
• Itching
• Hives
• Red, irritated skin
• Itchy ears
• Vomiting
• Diarrhea
• Itchy, runny eyes
• Ear infections
• Licking constantly

Autoimmune Conditions

Rarely, certain autoimmune diseases can cause dryness and cracking around the nose. If your dog’s nose appears to be changing color or texture, let your vet know.

Pemphigus

This autoimmune disease can affect the skin, including the nose, causing dryness, cracking, and sometimes crusting or discoloration. If you notice persistent dryness or changes in your dog’s nose texture or color, consult your vet to check for conditions like pemphigus.

Compare a normal dog nose to the nose of a dog with pemphigus

Heatstroke

On hot days, a warm nose could be one sign of heatstroke, especially if your dog is panting excessively, drooling, or appears weak. Heatstroke is a serious condition and requires immediate veterinary attention to avoid dangerous complications.

Symptoms of Heatstroke in Dogs

• Excessive panting
• Dehydration
• Excessive drooling
• No urine
• Fever
• A rapid pulse
• Lethargy
• Weakness
• Muscle tremors
• Dizziness
• Vomiting
• Diarrhea
• Gums are an unusual color

Caring for Your Dog’s Nose

If your dog’s nose frequently appears dry or cracked, you can help by:

• Keeping them hydrated
• Using a pet-safe balm or moisturizer recommended by your vet
• Limiting exposure to sun or extreme temperatures

When To Contact Your Vet

If your dog’s nose remains warm over several days, or if you notice other symptoms like vomiting, diarrhea, or changes in behavior, reach out to your vet. A warm nose, on its own, usually isn’t a cause for alarm, but it can sometimes be a clue when combined with other signs.
