It’s a danger every dog owner fears: heat stroke. It’s when a dog’s body temperature gets up to or exceeds 103 degrees, which can lead to organ failure and even death. 

But heat stroke isn’t the only warm weather danger that dogs face. If pet owners don’t take proper precautions dogs can become dehydrated, too. Plus—as most humans can attest—being outside on really hot days can be downright uncomfortable.

To prevent overheating, many pet parents have considered using dog cooling vests to keep their dog’s temperature regulated. But what is a cooling vest, how do they work, and are they beneficial to dogs? Learn more about these warm-weather accessories and read about our top dog cooling vest picks. 

What Is a Dog Cooling Vest?

Dog cooling vests work by keeping cool air against your dog’s body and warm air away from it. Most are designed to be comfortable and easy for dogs to wear while being active outdoors. 

There are different types of cooling vests for dogs. Some have a layer that requires water to create the cooling effect, while others use frozen gel packs. 

The most important thing to know about how these vests work: They are effective for a little while, until the ice completely melts or until they need to be re-wet and refreshed. Once the ice melts or water dries, they can actually make a dog more hot.

Dog Cooling Vest Buyer’s Guide

Aaron Rice, expert dog trainer and co-owner of Stayyy, a community for dog lovers and people who are looking to train their dog, reminds pet owners that “not all cooling vests are created equal.” 

Rice says to consider these factors when shopping for a dog cooling vest:

  • Size
  • Weight
  • Breed 
  • Age 
  • Where you live
  • Availability/ability to re-wet one or freeze one
  • If your dog will be willing to wear a vest at all

Rice also says to consider each use case for when you plan to use a vest. For instance, some will be better for active dogs who are running or exercising outdoors, while others will be better suited for leisurely walks or lounging in the yard. Make sure to choose a vest that fits your dog’s favorite activities and your overall lifestyle. You’ll also want to factor in how often you plan to use it during the warmer months. If you live in a particularly warm climate, you may use a dog cooling vest more than if you live somewhere with four seasons. If that’s the case, and you’ll be using the vest frequently, pay close attention to durability and look for vests with warranties. 

As for what not to buy? There are dog cooling vests that are not worth your money. “Some can be uncomfortable, don’t fit well, and don’t work as advertised,” cautions Rice. “Some dogs have a difficult time adjusting to the cooling vest, which can cause them to pant excessively and sweat more than usual.” 

Slowly get your dog used to wearing the cooling vest in and around your home using positive reinforcement with treats and praise. Only keep it on for a few minutes at a time and gradually work up to longer periods. If your dog seems uncomfortable in the vest, take it off and try again another time. 

At the end of the day, the best option for your dog is one that doesn’t restrict his movement and provides him with cool air at all times. 

Dog Cooling Vest FAQs

Here are some common questions (plus, answers!) about dog cooling vests…

Do dog cooling vests work?

Yes, dog cooling vests can help keep dogs cool by keeping cool air near their body using the evaporation method or with frozen gel packs. However, it’s important to keep in mind that these vests are not a long-term cooling solution and will stop working once the water evaporates and dries or the gel packs unfreeze. Once the vest dries or the ice packs are no longer frozen, the vest should be removed from your dog to prevent overheating.

Do dog cooling vests work right away?

It may take at least 15 minutes for the dog cooling vest to be effective. If your dog is in immediate need of a cool down, bring them to a shady spot, spray them with lukewarm water, and encourage them to drink. 

Are dog cooling vests worth it?

Overall, dog cooling vests can be beneficial if you spend time outdoors with your dog in warm temperatures. Most of these vests are relatively affordable and can provide some comfort to your dog on those high-temperature days. Plus, the vests tend to be durable and pet parents can get a lot of use out of them before needing to buy a replacement. However if you don’t spend much time outdoors with your dog during the summer months or you don’t live in a warm climate, your dog may not need a cooling vest. 

Will my dog get soaked by the vest if it’s wet?

While dog cooling vests do typically use water to activate, it doesn’t mean it should soak your dog. In fact, that can be very irritating to a dog. The dog cooling vest should absorb the water to cool the dog, but not drench the dog.

Tips for Using Dog Cooling Vests and Keeping Your Dog Cool

As with everything, it’s important to read directions for use. When you’ve selected the dog cooling vest that’s best for your pup, follow the guidelines that come with it. 

Most vests that use the evaporation method will need to be dipped in water, wringed out, and then placed on your dog. If you purchase a vest that uses gel packs, make sure the packs are frozen and insert them into the proper compartments before fitting the vest on your dog. Make sure to adjust and fit the cooling vest to your dog so that it’s not too tight or too loose. You should be able to slide two stacked fingers easily between the vest and your dog’s body.

Not all dogs will want to wear a vest—cooling or otherwise. Allow your dog to explore and get used to the vest at home, in a comfortable environment, before trying it out on a long walk or during a day trip. 

To keep your dog comfortable in the heat, use cooling vests in conjunction with other cooling methods. These include:

  • Providing your dog with plenty of fresh drinking water
  • Finding shady spot to rest
  • Using air conditioning or fans indoors if available
  • Misting your dog with a spray bottle
  • Avoiding walks or outdoor activities during the hottest times of day

While cooling vests provide some relief for dogs on hot days, they aren’t foolproof and shouldn’t provide pet parents with a false sense of security. If there’s a heatwave and it’s uncomfortable for you to be outside for long periods of time, it’s probably best to keep your dog indoors until things cool down.
