Do Dogs Have Sweat Glands in Their Paws?
Yes, dogs do have sweat glands located in their paw pads. However, they are not the dog’s primary cooling mechanism. These sweat glands, called merocrine glands, function similarly to human sweat glands. When a dog’s body temperature rises, the merocrine glands in the paw pads secrete sweat to cool the paws and remove some heat from the body. However, dogs mainly cool themselves through panting and dispersing heat through their nose and mouth. Sweating through the paw pads plays a lesser role in cooling. According to the AKC, “Although dogs do have some sweat glands, their primary source of heat exchange is panting.”

How Do Dogs Mainly Stay Cool?
Dogs primarily stay cool through panting and releasing heat through the mouth. Panting allows dogs to evaporate moisture from the tongue, throat, and lining of the mouth, which cools the blood flowing through these areas before it circulates through the rest of the body. When dogs pant, they inhale air through the nose and mouth, and exhale warm, moist air out across the tongue. This evaporation has a cooling effect that helps regulate body temperature (Source). The moisture produced also cools the blood in the mouth before it is pumped throughout the body by the heart. Panting helps dogs release excess body heat and is an essential cooling mechanism since dogs do not have many sweat glands.
Panting is a normal behavior for active or overheated dogs. Dogs pant when they exercise or play to help cool themselves down. Panting also increases when a dog is hot, stressed, or anxious to aid cooling. Excessive panting can be a sign a dog is too hot and needs help cooling down. Providing access to water, shade, a fan, or air conditioning can help an overheated panting dog (Source). Since panting is critical for regulating temperature, excessive panting or changes in normal panting patterns warrant a vet visit to check for potential health issues.
How Does Sweating Through Paws Help Dogs?
While dogs don’t rely on sweating through their paws as a primary method of cooling, the sweat glands in their paw pads do provide supplementary temperature regulation (1). When dogs sweat through their paws, it helps cool their body by evaporative cooling. As the sweat evaporates from the paws, it pulls heat away from the body. This provides an extra cooling mechanism to help regulate their temperature, especially in hot weather.
In addition to cooling, sweat on dog paws helps provide traction (2). Paw pads have a rough texture to help grip surfaces, but when conditions are slippery from rain, snow, or smooth floors, sweat from paw pads gives added stickiness. This allows dogs to maintain stability and prevent slips and falls. So sweating through paws assists dogs both in cooling down and staying on their feet.

When Might Paw Sweating Occur?
While dogs don’t rely heavily on paw sweating for temperature regulation, there are certain situations that can trigger minor sweating in the paws:
Hot Environments – Dogs may sweat slightly through their paws when in very hot weather or environments. The evaporation from the paw pads provides a small amount of cooling. However, this is minor compared to panting and other cooling behaviors.
Nervousness – Some dogs may exhibit slight paw sweating when nervous or anxious. This is similar to how humans sweat more when nervous. However, dogs mainly pant and seek shade when overheating.
Exercise – Strenuous exercise on hot days can lead to mild sweating through the paws as the dog’s body heat rises. This allows for minor evaporative cooling through the hairless paw pads. But panting and drinking water are more effective ways for dogs to cool post-exercise.
Overall, paw sweating in dogs is minimal and situational. While it can provide a small amount of temperature regulation, dogs mainly rely on panting, shade-seeking, and other behaviors to stay cool. Excessive paw sweating may indicate overheating or anxiety issues that require veterinary attention.
Do All Dog Breeds Sweat from Their Paws?
While all dogs have sweat glands in their paw pads, some breeds tend to sweat more from their paws than others. This is often seen in breeds that originated in warm climates or that have heavily furred paws.
For example, Siberian Huskies and other northern dog breeds tend to have more active sweat glands in their paws. This helps them cool down and regulate body temperature, especially when exercising or working in warmer environments. The thickness of fur on their paws holds the moisture and allows more evaporative cooling to take place (PetMD).
On the other hand, dogs with hairless paws or those from hot climates, like Chihuahuas or Basenjis, may not rely as heavily on sweating from their pads to stay cool. Their bodies are better adapted to warm environments through other means like panting.
So while all dogs sweat through their paws to some extent, some breeds definitely utilize paw sweating more than others as an effective cooling mechanism. Pay attention to your own dog’s paws on hot days to see if sweaty paw prints are a sign they may need help cooling down.
Are Dog Paw Pads Similar to Human Foot Pads?
While dog and human feet have some key differences, their paw pads and foot pads share certain anatomical similarities. Both contain fatty tissue to cushion and protect the paws from impact and abrasion. This tissue conforms to surfaces, provides insulation, absorbs shock, and aids grip and traction.
The top layer of the paw pad consists of keratin, a tough protein also found in human fingernails. This creates a thick callus to shield the foot. Underneath lies a layer of dense collagen fibers interlaced with blood vessels and nerves. Deeper still is the subcutaneous tissue containing fat cells and sweat glands.
However, a major difference is that dogs primarily sweat through their paw pads, whereas humans mainly sweat from their skin. Dogs only have sweat glands on their paws and noses. Humans also have more fat padding compared to dogs’ sturdier paw pads. And while human foot pads are relatively smooth, dogs have rougher textured pads with ridges and grooves to provide traction.
Overall, despite some clear anatomical distinctions, dogs and humans share the basic pad structure of hardness on the outside with soft cushioning within to protect their feet.

How to Keep Dogs’ Paws Cool
There are several tips to help keep your dog’s paws cool, especially in hot summer weather:
Use booties – Booties can protect your dog’s paws from hot pavement or sand. Look for breathable booties to avoid overheating their paws. Make sure to introduce booties slowly and give your dog time to get used to wearing them.
Try paw wax – Paw wax provides a layer of protection from heat and irritants. Apply a thin coat before walks. Paw wax can also help heal cracked paw pads.
Walk on grass – Opt to walk your dog on grass instead of concrete or asphalt whenever possible. Grass provides insulation and is cooler under their paws.
Avoid midday walks – Take walks early morning or evening when temperatures are cooler to avoid burning their paws.
Rinse paws – Gently rinse your dog’s paws with cool water after walks to wash away any irritants and help lower their temperature.
Consider a cooling vest or mat – Use a cooling vest or mat to help regulate your dog’s overall body temperature.
Check pavement temperature – Feel the pavement with your hand before walks. If it’s too hot for your hand, it’s too hot for paws.
Take breaks in shade – Rest regularly in shaded areas to give paws a chance to cool down.
Avoid exercise on hot days – Limit walks and intense play on excessively hot days to prevent overheating.
Ask your vet for tips – Consult with your veterinarian for additional breed-specific recommendations to keep paws cool.
Pay attention to signs of discomfort or overheating. Take measures to protect paws from hot surfaces. Providing insulation, shade, and cooling will help keep your dog’s paws healthy and happy.
Signs of Overheated Paws
Some clear signs that a dog’s paws are overheating include lameness, rawness, and burnt or blistered pad appearance. If a dog has been walking on hot pavement or sand, the high heat conduction can easily overheat their paw pads. According to the AKC, signs of mild paw pad burns include inflamed, pink skin and blisters on the pads (AKC). More severe burns may cause dark, scabbed skin, cracks, or deep wounds on the pads. Lameness or limping can occur if the burns are painful enough that the dog avoids stepping on the sore paws. Keeping the paws cooled down with water or booties and avoiding hot surfaces is key to preventing this painful overheating.
In addition to visual signs, dogs may excessively lick or chew at their sore paws if they are burnt. They may also whine or yelp when the paws are touched. It’s important to check a dog’s paws after any activities on hot surfaces and provide first aid treatment to prevent infection. For severe paw pad burns or ongoing lameness, it’s best to get veterinary attention right away.
When to See the Vet for Paw Issues
There are certain signs that indicate your dog’s paws require veterinary attention. These include limping, injuries, burns, and allergies.
If your dog is limping or holding their paw up, they may have an injury or irritation. Cuts, punctures, torn nails, and broken bones can all cause limping. Your vet can treat these injuries, provide pain medication, and suggest rest and recovery. For severe injuries like broken bones, surgery and casting may be required. According to The Spruce Pets, deep lacerations often need surgical repair by a vet [1].
Burns need urgent veterinary care to prevent infection and promote healing. Chemical and heat burns like from pavement or engine fluids require flushing, antibiotics, pain control, and bandaging. Electrical burns also need medication, debridement, and monitoring [1].
Allergic reactions to grass, pollen, or chemicals can inflame and irritate paws. Itching, redness, and swelling are signs of allergy. Oral medication, ointments, or allergy testing may be recommended. Controlling exposure to allergens can also help relieve symptoms.
At the first signs of limping, injuries, burns, or allergies, it’s important to have your veterinarian examine your dog’s paws. Proper treatment will relieve discomfort and prevent complications.
Keeping Paws Healthy
Keeping your dog’s paws healthy is an important part of overall care and wellness. Here are some tips for maintaining healthy paws:
Regular cleaning is essential. After walks or playtime outside, wipe your dog’s paws with a damp washcloth or pet wipes to remove dirt, salt, chemicals, and other irritants. Use a gentle dog shampoo or mild soap and water if the paws are very dirty. Make sure to rinse and thoroughly dry the paws after cleaning.
Moisturizing helps prevent cracks and irritation. Paw balms, butters, or oils can be massaged into the pads and foot hair to condition the skin and keep it supple. Look for natural moisturizers containing vitamin E, shea butter, coconut oil, or beeswax. Apply moisturizer anytime the paws seem dry and cracked.
Trimming the hair between toes and on foot pads keeps debris from getting trapped and matted. Use rounded tip grooming scissors to carefully trim around the edges and undersides of paws as needed. Never shave off all the hair, as this protects paw pads.
With proper paw hygiene and care, you can keep your dog’s feet healthy and happy.
