A dog’s nose is one of their most important organs. Not only does it allow them to sniff out food, track scents, and capture odors, but it also helps regulate their body temperature. That’s why it’s crucial to pay attention to your dog’s nose and watch for any changes in its normal moistness.

A persistently dry dog nose can be a red flag signaling that your pup is dehydrated and needs more water.

What Causes a Dog’s Nose to Become Dry?

There are a few key reasons why your dog may develop a parched, dried-out nose:


Dehydration is the #1 cause of dry dog nose. Dogs who aren’t getting enough fresh water will often have flaky, cracked noses because they lack adequate moisture levels throughout their body. Prolonged dehydration leads to the drying out of mucus membranes, including those in the nose.

Hot, Dry Environments

Dogs who spend time outdoors in hot, arid climates are also prone to dry noses. The sun and dry air simply zap any existing moisture right out of their noses! This frequently happens when dogs are outside in the peak heat of summer or are living in desert regions.

Medical Conditions

Certain medical conditions like fever, kidney disease, diabetes, and hyperthyroidism can cause excessive panting and water loss, leading to dehydration and nose dryness. Some medications like diuretics also increase urination and dehydration risks.

Old Age

Senior dogs may develop a chronically dry nose as their mucus-producing cells start to wear out with age. Their noses simply don’t generate as much protective mucus as they used to when they were younger.

Indoor Heating or Air Conditioning

Heating systems in the winter and air conditioning in the summer both create dry indoor air. This environment can then sap moisture from your dog’s nose. The dryness is compounded if your dog is already dehydrated.

Signs Your Dog is Dehydrated

How can you tell if your dog’s dry nose is related to dehydration? Look for these other telltale signs of inadequate hydration:

• Dry or sticky gums and mouth
• Lethargy, weakness, or collapse
• Loss of skin elasticity or “tenting” skin
• Sunken eyes
• Thick or tacky saliva
• Loss of appetite
• Vomiting or diarrhea
• Dark yellow urine or urinating less frequently

If you spot any of these symptoms along with a dry nose, it’s very likely your dog needs more fluids. The only way to truly diagnose dehydration though is to have your vet examine your dog and run some tests. But in most mild cases, simply upping water intake resolves the problem.

Health Risks of Dehydration in Dogs

It’s imperative to keep your dog well-hydrated because dehydration can have serious consequences including:

• Impaired body temperature regulation
• Reduced oxygen delivery to cells
• Organ damage or failure
• Seizures or coma
• Death (in severe cases)

Dehydration is considered a medical emergency once it reaches 10-12% water loss in dogs. Even before it gets that bad though, dehydration can make dogs very sick. So don’t ignore a chronically dry nose or other signs your dog isn’t getting enough to drink. Mild dehydration left untreated can progress to more hazardous fluid and electrolyte imbalances.

Tips to Keep Your Dog Hydrated and Nose Moist

How can you ensure your dog is well-hydrated and has an adequately moist nose? Try these pro tips:

• Always provide unfettered access to fresh, clean drinking water. Make sure your dog has a bowl that is routinely scrubbed and topped off with water. Change water at least twice daily. Consider getting a filtered water fountain bowl to entice drinking.

• Offer wet food, broths, etc. Incorporating canned food, broths, gravy, and ice cubes into your dog’s diet adds extra hydration from licking and eating the wet contents.

• Monitor water intake. Get familiar with your dog’s normal daily water consumption so increases or decreases are noticeable. Sudden changes in intake can signal an issue.

• Rule out health problems. Schedule yearly checkups to have your vet evaluate for any underlying diseases contributing to dehydration. Diagnose and treat any medical conditions.

• Bathe and groom dogs routinely. Bathing and brushing keep their coat and skin clean while trimming the hair around the mouth prevents drinking obstacles.

• Always bring water on walks. Make water easily available anytime you take your dog out in the heat or for long periods. Portable folding bowls are perfect for on-the-go hydration.

• Limit exercise when hot. Avoid strenuous exercise on sweltering days to prevent overheating and heavy panting that leads to water loss. Exercise early or late when cooler instead.

• Use a humidifier. Run a humidifier near your dog’s bed during dry winter months or in air-conditioned rooms to add moisture back into the air to protect their nose.

• Try a moisturizing balm. If your dog has a perpetually dry nose even when well-hydrated, ask your vet about special nose balms to hydrate and protect tender skin.

When to See the Veterinarian

While mild dry nose from environmental factors isn’t a major concern, you should still have your dog seen by a vet if:

• The dry nose persists longer than 1-2 days after increasing water intake
• It occurs along with other symptoms of dehydration
• It happens repeatedly
• Your dog seems ill, lethargic, or distressed
• The nose becomes flaky, cracked, or bleeding

Your vet can run tests to evaluate if there is an underlying health issue causing the dehydration. They can also provide personalized recommendations to help moisturize and protect your dog’s sensitive nose skin.

With vigilance and proactive hydration care, you can help keep your furry friend’s nose in top condition. Pay attention to signs of inadequate fluid intake and take action at the first hint of dryness. Providing unlimited clean drinking water and creating a hydrating care routine will help keep your dog’s nose supple, moist, and healthy for years to come.

FAQs About Dry Dog Noses and Dehydration

How can I tell if my dog’s nose is too dry?

Look for a nose that appears parched, flaky, cracked, or rough. Notice if their nose lacks the usual subtle sheen and moisture. Dry noses often feel dry and leathery too.

What is a healthy moisture level for a dog’s nose?

Ideal nasal tissue should look moist but not wet. There should be no discharge, stickiness, or dripping liquid. The nose feels smooth, spongy, and supple. When you press it, it springs back instantly.

How soon after drinking will my dog’s nose rehydrate?

Increases in bodywide hydration happen gradually, so dry noses don’t resolve immediately. It often takes several hours up to 24 hours for moisture levels to replenish after a dog drinks adequate fluids.

Should I use nose balm on my dog’s dry nose?

You can try using a gentle, non-toxic nose balm recommended by your vet. However, the root cause of the dryness needs to be addressed first through proper hydration. Balms provide extra protection but don’t cure underlying dehydration.

What humidity level is healthiest for my dog?

Ideally, the humidity in your home should be kept between 45-50% to protect your dog’s respiratory tract and nasal membranes from becoming overly dried out.

When is a runny nose a concern in dogs?

A persistently runny nose could indicate an illness like a respiratory infection. It should be evaluated by a vet if it occurs for more than 24 hours, is a thick/colored discharge, happens along with lethargy or appetite issues, or if your dog seems uncomfortable.

Do dogs sweat through their nose?

Dogs only have sweat glands on their paws and noses. So while a small amount of moisture on the nose may be sweat, excessive nasal wetness likely indicates illness. Panting and increased salivation as a means of cooling are much more common in dogs than sweating.
