As noted earlier, high temperatures inside your car can kill your dogs. You can keep your dog cool inside the car on hot summer afternoons by doing the following.

How To Keep A Dog Cool In A Car

Use Reflective Window Shades

When you’re driving in the heat of the day, don’t forget to put up your reflective window shades! This will help reflect some of that sun and make it cooler for your dog. Aluminum window shades are great because they won’t rust or break down over time like wooden ones do. They also have a reflective coating which helps prevent sunburns on your dog.

The shades reflects heat away, keeping your dog cool.

Use Petgear Car Window Guard

If you use any kind of pet carrier or crate, this is an absolute must-have item. It keeps the windows from rattling around when you drive and prevents them from getting damaged. The window guard is easy to install and comes with detailed instructions so you shouldn’t have any trouble putting it up. A window guard ensures you can leave windows open for air to circulate while you’re away.

Cool Dog Tailgate Lock

Most tailgates come equipped with a lock, but if yours doesn’t, you should get one. Your dog may try to jump out of the car at stop lights or other traffic jams and he could easily be injured. Also, if you need to quickly exit your vehicle, having a locked tailgate makes it much easier. You may need professional help to install it though.

A Tailgate lock works by having the keypad outside the door slightly and allowing air to circulate freely. leave the front windows slightly open for the breeze to enter and leave by the trunk. The technique is also used in most apartments where the front door and back door open. You end up creating a wind tunnel that passes through cooling your car.

Keep Your Dog Hydrated

Make sure to always have water available for your dog when he is riding along with you. Dogs are naturally much more active than people, so they need a lot of fluids. Get a portable water bowl or even better – get one of those collapsible bowls which allow you to carry them around easily.

Invest In A Cooling Pad

If your dog has been sitting too long in the back seat, then you may want to invest in a cooling pad. These pads come in different sizes but usually fit well under the seat in front of the dog. They work best when there is air flow between the dog and the cushion.

You can also use a cooling vest for the same purpose.

Keep AC ON At All Times

Make sure you keep your car AC the moment you leave it. You want to set the right temperature settings before leaving. For dogs, the ideal body temperature is 101.0 to 102.5°F.

Wireless Temperature Monitoring Sensors

You can install a temperature sensor to alert if your temperatures go beyond a certain level. This way, you can always monitor your car temperatures even when away.

The last thing you want to do is leave your dog alone in the car while you go into the store. Even if your dog seems fine right now, he could quickly start feeling ill once the temperature starts rising.
