Skin—Animals and Sweat

Sweating is a natural and efficient way for humans to cool down. When our body temperature rises, sweat glands release moisture onto the skin, and as this moisture evaporates, it helps regulate our temperature. This mechanism allows us to adapt to varying climates and physical activities effectively.  

But for our furry companions—cats and dogs—sweating plays a much smaller role in staying cool. Instead, our pets animals rely on unique adaptations to manage heat and keep their body temperature in check. By understanding how pets regulate heat, we can better support their comfort and health, especially during warmer months.

Do Cats and Dogs Sweat?

Cats and dogs do have sweat glands, but they function quite differently from those of humans. Instead of being spread across their entire body, the sweat glands in cats and dogs are primarily located in their paw pads. You may have noticed your dog or cat leaving faint damp paw prints on a hot day—this is one of the few ways their bodies use sweat to cool down.  

However, sweating is not an effective cooling mechanism for cats and dogs. Unlike humans, whose sweat glands are widespread and support evaporation across the body, the limited number of sweat glands in their paws can’t sufficiently reduce body temperature. As a result, cats and dogs have evolved alternative strategies to stay cool, such as panting, seeking shade or limiting activity. Understanding these differences is key to helping pets manage heat effectively.

How Cats and Dogs Regulate Heat

Panting

For dogs, panting is the primary way to cool down. As they breathe rapidly, moisture evaporates from their tongue, nasal passages and the lining of their lungs, helping to lower their body temperature. Cats may pant occasionally, though this is less common and often a sign of stress, overheating or illness.

Grooming

Cats also use grooming as a way to cool down. By licking their fur, they deposit saliva, which then evaporates to create a cooling effect—similar to sweating in humans, but on a smaller scale.

Behavioural Adaptations

Cats and dogs instinctively adjust their behaviour to manage heat. They seek out shaded areas, lie on cool surfaces such as tile or concrete, and reduce their physical activity during hot weather. These natural behaviours help conserve energy and maintain a safe body temperature.  

Skin Health and Temperature Regulation

Healthy skin is essential for efficient temperature control in pets. While sweating isn’t their main cooling mechanism, the skin still plays a critical role in heat regulation. For instance, open and clean pores, especially in wrinkly-skinned dogs, allow for better air circulation. Similarly, healthy paw pads can maximise the small amount of cooling they provide.

However, issues such as clogged pores, irritated skin or cracked paw pads can interfere with these processes. Conditions like dermatitis or infections may increase discomfort and make it harder for pets to manage their body temperature effectively.

Managing Heat in Pets

Practical Tips

• Hydration: Always provide fresh, clean water to keep pets hydrated.

• Shaded Spaces: Ensure your pet has access to shaded areas, both indoors and outdoors.

• Cooling Mats: Use cooling mats or damp towels for pets to lie on during hot days.

• Grooming: Regular grooming helps keep fur free of mats and facilitates better heat dissipation.

Signs of Overheating

Watch for symptoms such as excessive panting, drooling, lethargy or difficulty breathing—these can be signs of overheating or heatstroke. In severe cases, pets may collapse or have seizures. If you notice any of these signs, seek veterinary care immediately.

By understanding how pets regulate heat and taking proactive steps to manage their environment, you can help ensure they stay cool and comfortable, even during the hottest days.
