Do Dogs Sweat? Vet’s 2025 Guide to Canine Cooling, Sweat & Heat Safety 🐶🌡️

By Dr. Duncan Houston BVSc

Hello—I’m Dr Duncan Houston BVSc, veterinarian and Ask A Vet founder. While dogs don't sweat like humans, they do have sweat glands—in their paws and noses. This vet‑approved guide unpacks:

How and where dogs sweat
Their primary cooling strategies
What paw‑sweat means
Signs of overheating or heatstroke
Paw‑care & summer safety tips
Ask A Vet tools for tracking heat‑risk and paw health

1. How Do Dogs Sweat?

Merocrine glands are located in the paw pads (and nose); they release sweat when dogs are hot or stressed—sometimes leaving damp paw prints.
Apocrine glands are distributed across the skin and secrete pheromones—not used for cooling.

2. Primary Cooling Methods

Panting: Dogs breathe rapidly with an open mouth to evaporate moisture from their nasal passages, tongue, and lungs—this is their main cooling mechanism.
Vasodilation: Your dog’s blood vessels (especially in ears, face) expand, bringing heat to the surface to dissipate.
Paw sweat: A minor cooling method and traction aid, not a major thermoregulator.

3. What Paw‑Sweat Tells You

Heat stress: Damp paw pads + panting or warm ears often mean overheating.
Stress or anxiety: Moist paws can signal nervousness, such as at the vet.
No odor: The “corn chip” smell often comes from bacteria, not sweat.

4. Overheating & Heatstroke Signs

Heavy panting, drooling, red gums/skin, weakness or collapse.
Warm to touch, rapid heartbeat, vomiting, seizures—medical emergency.
High‑risk breeds: brachycephalic (pugs, bulldogs), seniors, dark‑coated, obese dogs.

5. Paw‑Care & Heat‑Safety Tips

Check paws after walks; if wet, gently dry—watch for hot pavement.
Provide shade, fresh water, and avoid midday exercise in summer.
Support healthy coat—don’t shave double‑coated dogs; grooming helps.
Spritz or use fans/cooling vests to assist cooling.
Never leave your dog in a hot car—even briefly.

6. Ask A Vet Support Tools

Heat‑sign tracker (panting, paw dampness, behavior changes)
Paw‑care logs for drying/inspection habits
Alerts for heat‑danger thresholds and care reminders
Guidance templates for cooling plans and activity timing

📌 Final Thoughts from a Vet

Dogs do sweat, but only through their paw pads and noses—and it's a minor part of their cooling system. Panting and vasodilation are their main strategies. Paw‑sweat can signal heat stress or anxiety. With smart heat‑management, paw care, and Ask A Vet tools, you can help your pup stay safe, comfortable, and cool—especially during summer fun. 🐾❤️
