What to consider for Dog Cooling Vest For Dogs Over 80 Lbs
When choosing a cooling vest for a large dog over 80 lbs, size and fit are critical. Many vests have weight limits that top out around 100 lbs, so ensure the vest you choose accommodates your dog’s chest girth and length. Look for vests with extended sizing or adjustable straps to accommodate deep chests and broad shoulders common in large breeds. Evaporative cooling technology works best in low humidity, so consider your climate. Also, check that the vest is machine washable and durable enough to withstand active use.
What to look for in a gear item (harness, collar, leash or muzzle)
For a cooling vest, correct fit and sizing are paramount: measure your dog’s girth and length and compare to the manufacturer’s size chart. Durable hardware and materials are important for large dogs that may pull or chew. Safety features include reflective trim for visibility, and a design that doesn’t restrict movement or cause chafing. Comfort and padding are essential for extended wear. A no-pull design isn’t typically relevant for cooling vests, but a secure closure system (buckles, velcro) prevents the vest from shifting.

View on Amazon
The Ruffwear Swamp Cooler uses a three-layer evaporative design that keeps dogs cool without being wet. It fits dogs up to 120 lbs with an adjustable chest strap. The durable ripstop fabric withstands rough play. However, it is pricier than other options and may not work as well in humid climates.
The Kurgo Core Cooling Vest offers effective evaporative cooling at a lower price point. It fits dogs up to 110 lbs and features a reflective trim for visibility. The vest is lightweight and easy to pack. A downside is that the sizing can be tricky for deep-chested breeds, and the velcro closure may wear over time.
Chai's Choice Cooling Vest is designed specifically for large breeds, fitting up to 150 lbs. It uses a three-layer evaporative cooling system and has a secure buckle closure. The vest provides good coverage for the chest and back. One limitation is that the material can feel bulky, and the cooling effect diminishes faster in high humidity.
While primarily a cooling vest, the PetSafe Cool Pup features a front clip that can attach to a leash to discourage pulling. It fits dogs up to 100 lbs and uses evaporative cooling. The vest is machine washable. However, the cooling layer is less effective than dedicated cooling vests, and the no-pull feature may not work for strong pullers.
The Rabbitgoo Dog Cooling Vest is lightweight and breathable, making it suitable for training sessions. It fits dogs up to 120 lbs and has reflective strips for safety. The vest uses evaporative cooling and dries quickly. A drawback is that the velcro straps may not hold securely on very active dogs, and the sizing runs small.
Evaporative cooling vests are the most common and work by soaking the vest in water, then the evaporation process draws heat away from the dog. Ice pack vests provide longer cooling but can be heavy and cause cold burns if not insulated. Phase change materials maintain a constant temperature but are more expensive.

05
Safety Features
Reflective trim or stitching improves visibility in low light conditions. Ensure the vest does not restrict breathing or movement. Avoid vests with small parts that could be chewed off and swallowed.
Living With It
Care, Cost and Maintenance
Washing
Most cooling vests are machine washable. Use cold water and a gentle cycle, then air dry. Avoid fabric softeners as they can reduce the cooling effect. Check the care label for specific instructions.
Storage
Store the vest in a cool, dry place away from direct sunlight. If using an ice pack vest, remove the packs and store them separately. Ensure the vest is completely dry before storing to prevent mold.
Activation
For evaporative vests, soak in water for a few minutes, then wring out excess water. Some vests require activation by rubbing or shaking. Follow the manufacturer's instructions for best results.
Pro tip
For maximum cooling, wet the vest with cold water and store it in the refrigerator (not freezer) for 10 minutes before use. This enhances the cooling effect without risking cold burns.
Frequently asked questions
How do I measure my dog for a cooling vest?
To measure your dog for a cooling vest, you need two key measurements: chest girth and back length. Chest girth is measured around the widest part of the chest, just behind the front legs. Back length is measured from the base of the neck (between the shoulder blades) to the base of the tail. Use a flexible measuring tape and ensure your dog is standing. Compare these measurements to the manufacturer's size chart. For dogs over 80 lbs, pay attention to the maximum girth and length supported. If your dog is between sizes, choose the larger size for comfort.
Are cooling vests effective for no-pull training?
Cooling vests are not designed for no-pull training. Their primary purpose is to keep your dog cool. However, some vests, like the PetSafe Cool Pup, have a front D-ring that can be used to attach a leash, which may help reduce pulling by redirecting the dog's attention. For serious pulling issues, a dedicated no-pull harness with a front clip is more effective. Combining a cooling vest with a separate no-pull harness is possible, but ensure the vest does not interfere with the harness fit.
Can a cooling vest be escape-proof for large dogs?
Cooling vests are generally not escape-proof. They are designed for comfort and cooling, not security. Most vests use velcro and buckles that can be undone by a determined dog. If your dog is prone to escaping, look for vests with multiple adjustment points and secure buckles. However, for dogs that are escape artists, a well-fitted harness may be a better choice for walks. Always supervise your dog when wearing a cooling vest, especially if they are not used to it.
Should I use a cooling vest or a harness for my large dog?
A cooling vest and a harness serve different purposes. A cooling vest is for temperature regulation, while a harness is for control and safety during walks. You can use both together: put the harness on first, then the cooling vest over it, as long as the vest does not restrict the harness straps. Some cooling vests have D-rings for leash attachment, but they are not as sturdy as harness rings. For walks, always attach the leash to a harness, not the vest, to ensure control.
What materials are best for durability in a cooling vest?
For durability, look for cooling vests made from ripstop nylon or polyester. These materials resist tearing and abrasion. Reinforced stitching at stress points, such as buckles and straps, adds longevity. Avoid vests with thin or flimsy fabric that can easily rip. Also, check that the cooling layer is securely enclosed to prevent leakage of gel or water. Hardware should be rust-resistant, such as stainless steel or coated metal. Velcro closures should be strong but may wear over time.
How do I wash a cooling vest?
Most cooling vests are machine washable. Use cold water on a gentle cycle and mild detergent. Do not use bleach or fabric softener, as they can damage the cooling material. After washing, air dry the vest away from direct heat. For vests with removable ice packs, take them out before washing. Some vests may be hand wash only, so always check the care label. Proper washing helps maintain the cooling effectiveness and extends the life of the vest.
Do cooling vests work differently for small vs large dogs?
Cooling vests work on the same principle regardless of dog size, but the fit and coverage matter. For large dogs over 80 lbs, the vest must cover a larger surface area to be effective. Some vests have extended sizes specifically for large breeds. Large dogs also generate more body heat, so the cooling effect may need to be more robust. Evaporative vests may need to be re-wetted more often for large dogs. Ensure the vest fits snugly to maximize contact with the skin for heat transfer.
Are there any safety concerns with cooling vests?
Safety concerns with cooling vests include potential for overheating if the vest is not used correctly. Evaporative vests require water to work; if they dry out, they can trap heat. Ice pack vests can cause cold burns if the packs are not insulated. Always follow the manufacturer's instructions. Ensure the vest does not restrict breathing or movement. Never leave your dog unattended while wearing a cooling vest. Also, check for any signs of irritation or chafing, especially in the armpit area.
What is the best way to activate an evaporative cooling vest?
To activate an evaporative cooling vest, soak it in cool water for 2 to 5 minutes, or until the inner layer is fully saturated. Then, wring out the excess water so the vest is damp but not dripping. Some vests require you to rub or shake them to activate the cooling crystals. The vest will stay cool for several hours as the water evaporates. In dry climates, the cooling effect lasts longer. Re-wet the vest as needed to maintain cooling. Avoid using hot water, as it can reduce effectiveness.
