Chilling Out in the Sun: Why Your Dog Needs a Cooling Harness

By Canada Pooch on Sep 4, 2023

As temperatures rise, our pups can quickly overheat when outdoors. Unlike humans who can sweat to regulate body temperature, dogs primarily cool themselves by panting and through the pads on their paws. This makes hot sunny days potentially dangerous for our pups. Using a cooling harness or vest is an easy way to help your dog stay chill when the mercury climbs. 

How Dogs Regulate Body Temperature 

In order to fully understand why cooling vests and other wearables are so useful and often necessary for dogs in high-heat conditions, it helps to first closely look at the ways in which our dogs are able to regulate their body temperature. Dogs primarily rely on three major mechanisms to control heat dissipation and maintain a safe core temperature. 

Panting as the Main Cooling Method 

Panting serves as the primary means by which dogs are able to cool themselves down. As a dog pants, he rapidly breathes in and out, bringing air over his moist tongue, mouth tissues, and upper airway. 

As this air flows over the moist surfaces, it facilitates evaporative cooling. The moisture from the tongue and tissues evaporates into the air, dissipating heat in the process. This cooled blood then circulates through the dog's body, lowering the core temperature. 

Panting increases in intensity as a dog becomes hotter. How quickly and heavily a dog pants corresponds directly to how overheated they feel. Thus, panting serves as an important indicator of risk for hyperthermia and heat stroke. Dogs will pant much harder and faster when they are excessively hot compared to mild panting when they are only moderately warm. 

Thermoregulation Through Paw Pads 

In addition to panting, dogs also utilize their paw pads to help regulate temperature. The pads on a dog's feet contain numerous sweat glands. As temperatures rise, these sweat glands release moisture onto the pads. As the moisture evaporates from the paw pads, this provides a secondary form of evaporative cooling. 

Since dogs' paws contain a dense network of blood vessels, cooling the blood in the feet and paws leads to cooling of the overall circulatory system and body. However, the paw pads comprise only a small surface area compared to the evaporative effects of panting. So while helpful, sweating from the paw pads plays a secondary role in cooling. 

Behavioral Adaptations 

Dogs may also utilize certain behaviors to help them stay cooler in high-heat conditions. Seeking shady areas or cooler ground to lay on can provide some relief. Digging holes in dirt or sand buries the dog in cooler subsurface soil. Drinking more water helps replace fluid loss. However, these behavioral adaptations provide only minimal cooling effects. 

Lack of Sweat Glands 

Importantly, dogs have very few sweat glands present on their bodies relative to humans. While humans cool mainly through sweating from our extensive glands distributed over our skin, dogs lack this capability. This leaves them heavily reliant on just panting and paw pad sweating to dissipate heat. 

In summary, while panting and paw pads provide dogs some natural cooling capacity, these mechanisms are insufficient to prevent hyperthermia and heat-related illness on hot, sunny days or with prolonged vigorous activity. This demonstrates the clear value of cooling wearables to help keep pups safe and comfortable in high heat conditions when their own cooling abilities fall short. 

How Cooling Vests Work 

When you put a cooling vest on your dog, you might wonder - how does this thing actually work to keep my pup from overheating? The science behind the magic of cooling vests is pretty neat! Let's break it down into the key ways these vests are designed to help keep your furry friend feeling cool as a cucumber. 

Soaking Up the Sweat 

The layer of the vest touching your dog's skin is made of special sweat-wicking fabrics designed to soak up moisture. Before you head out into the heat, you wet down the vest. As your pup plays and pants, the vest absorbs all that doggie sweat and puts it to good use! 

The moisture in the vest fabric evaporates away, pulling heat along with it. This evaporative cooling effect works just like when your dog pants - moisture on the tongue evaporates and cools the blood. The vest creates much more surface area for evaporative cooling! 

Bouncing the Rays 

You know how black clothing absorbs heat from the sun and light colors stay cooler? Cooling vests use light, reflective outer fabrics that bounce the sun's rays off instead of soaking them up. 

This prevents the vest from getting extra toasty from all that sunshine beating down. Keeping the sun's heat off the vest helps it maintain maximum chilling power for your pup! 

Letting the Breeze In 

These vests wrap snugly around your pup’s back, sides, and belly so that air can flow freely around your pup. This circulation allows fresh breezes to sweep under the vest, carrying heat away from your dog's body. 

The tight fit also keeps the cooling inner fabric in close contact with your dog's skin for better heat transfer. 

Covering All the Bases 

Cooling vests don't just cover your dog's back - they wrap all the way around the sides to the belly too. This allows for maximum coverage of your pup's core body areas, rather than cooling just a small spot. 

More coverage = more cooling power! The expansive coverage keeps your dog's chest, back, and organs nice and chilled. 

Pretty neat, right? With all these cooling technologies working together, cooling vests help keep your pup safe and comfortable even when the mercury rises! 

Choosing the Best Cooling Vest or Harness 

Ensuring a Secure, Snug Fit 

One of the most critical features to look for is a design that provides a snug, secure fit against your dog's body. Adjustable straps at the neck, chest, belly, and shoulders allow custom tailoring the vest's fit precisely to your dog's proportions. 

A tight yet comfortable fit ensures maximum contact between the cooling fabric and your dog's back and sides. This enhances heat transfer away from the body. A loose vest allows air gaps that reduce cooling effectiveness. Check out the Chill Seeker Cooling Harness at Canada Pooch. 

Choosing Optimal Fabrics 

Pay close attention to the types of fabrics utilized in potential cooling vests. Lightweight, breathable mesh or perforated fabrics maximize airflow to your dog's skin and ambient air circulation to carry heat away. 

Avoid solid non-breathable fabrics that can block air movement. Also ideal are reflective outer layers to minimize solar heat absorption. 

Maximizing Body Coverage 

Seek out vests offering full torso coverage from neck to belly instead of partial coverage. The more skin surface area covered by the cooling fabric, the greater the heat dissipation capabilities. Full coverage is best for keeping core body temperature down. 

Evaluating Convenience Features 

Look for convenience details like easy on/off buckles, leash attachments, and machine washable fabrics. These features streamline real-world use when you'll be taking the vest on and off frequently. 

Assessing Quality and Reviews 

Finally, be sure to verify the vest's construction quality, durability and real-world effectiveness. Check product reviews and materials to avoid poorly made imitations. Investing in a well-made, high-performance vest helps keep your dog safe. 

Using a Cooling Vest Safely 

While cooling vests are extremely helpful for keeping dogs comfortable and safe in hot weather, they must be used properly. It is essential to follow certain precautions and usage tips to avoid potential health risks and optimize your pup's relief from the heat. 

Supervise Your Dog 

Never leave your dog unattended while wearing a cooling vest. Actively monitor them for signs of distress, overheating, or other concerns. Dogs can still suffer heat stroke even with a vest if not supervised. 

Avoid Chilling Too Much 

Check that your dog does not get too cold while wearing the vest. Look for shivering, lethargy, whining, and other clues they may be becoming over-chilled. Take brief vest breaks if needed. 

Follow Re-Wetting Directions 

During prolonged heat exposure, repeatedly wet the vest as directed to maintain max cooling power. The vest's effectiveness drops as moisture evaporates over time. Re-wetting restores cooling capacity. 

Watch for Skin Irritation 

Remove the vest right away if you see signs of skin irritation or rubbing. Discontinue use if rashes, welts or other reactions develop. Switch to a different style if needed. 

Hydration Is Still Critical 

Do not substitute the cooling vest for regular water breaks. Proper hydration remains essential for keeping your dog safe in heat. 

Monitor for Heat Distress 

If your dog pants heavily, drools excessively or shows other signs of heat distress, immediately move them to shade or air conditioning as needed. Do not overly rely on the vest. 

Consult Your Veterinarian 

Discuss any special precautions with your vet if your dog has medical conditions impacting their ability to regulate temperature or tolerate heat. Their advice is crucial. 

By following these important guidelines, cooling vests can help to make hot summer days much more pleasant and safer for your dog. With proper precautions, your pup can fully enjoy summer fun while avoiding overheating! 

From sweltering summer hikes to backyard play sessions, a quality cooling vest is essential gear for keeping your dog safe and comfortable when temperatures spike. Choose an evaporative or cooling gel vest that fits securely, covers the body, and has convenient features for easy use. With appropriate precautions, cooling wearables help prevent overheating while enabling your pup to enjoy the summer fun.
