How to Keep Your Dog Cool in an RV

If you’ve ever left your dog alone in an RV and spent the entire time away wondering whether the air conditioner was still running, you’re not alone.

We had a traumatizing experience during a campground stay in Florida when we lost power more than 20 times in a single day while we were about two hours away exploring Devil’s Den. Yes, 20 times!!

Thankfully, our temperature monitor alerted us every time the power went out, and the temperature inside the RV never reached a level that concerned us. But the experience reinforced just how quickly things can change when you are relying on air conditioning to keep your pet comfortable.

The good news is that keeping your dog cool in an RV really isn’t complicated. Most of it comes down to reducing heat inside the RV, having a plan for hot weather, and knowing how you will respond if something goes wrong.

In this post, we’re sharing how we keep heat out of the RV, the steps we take to help Coco stay comfortable during hot weather, and the backup systems we rely on when the power goes out.

Start by Keeping Heat Out of the RV

The easiest way to keep your dog cool in an RV is to prevent the RV from heating up in the first place.

Close Blinds and Shades

Before we leave the RV for more than 30 minutes or so, we close most of our blinds and shades to help block direct sunlight from coming inside. We usually leave a few partially open around the sofa because Coco loves to people-watch and keep an eye on what’s happening outside.

Tinted Windows vs. Reflectix

Many RVers use Reflectix in their windows to help reduce heat and say it is amazing.

Personally, we chose to tint the windows in our RV instead because we still wanted to be able to enjoy the view while cutting down on some of the sun’s heat.

Both approaches can help reduce heat inside the RV. We simply preferred a solution that still allowed us to see outside without constantly putting window coverings up and taking them down.

Choose Shade Whenever Possible

Whenever possible, we also try to choose campsites with some shade, especially during the hottest months of the year. A shaded campsite can make a huge difference in how hard your air conditioners have to work throughout the day.

We know not everyone has the luxury of choosing their campsite, but if shade is available, it is one of the easiest ways to help keep your RV cooler.

Give Your Dog a Cool Place to Rest

We also pay attention to where Coco can rest.

Most of our RV is covered with Muddy Mats because they do an incredible job of trapping dirt, sand, grass, and mud before it gets tracked through the RV.

But on especially hot days, we’ll sometimes pull up the large rug in front of the sofa before leaving. That gives Coco access to the cooler flooring underneath if she wants a place to stretch out and cool down.

She also loves our leather sofa as it tends to stay cool.

Help Your RV Stay Cool

Keeping heat out of the RV is only half the battle. You also need to help your cooling system keep up with the temperatures outside.

Run the AC Before Temperatures Climb

One of the biggest things we have learned is that it is easier for an air conditioner to maintain a comfortable temperature than it is to cool down an already hot RV. On warm days, we set our air conditioners to kick on before the RV starts getting uncomfortable.

In our current fifth wheel, we have three air conditioners. When we’re connected to 50-amp power, we keep all three set to maintain 74 or 75 degrees. Even then, the actual temperature inside the RV is often a little warmer than the thermostat setting, especially during the hottest parts of the day.

This approach may not be the most energy-efficient option, but keeping Coco comfortable is our priority during extreme heat.

Know Your RV’s Limits

We’ve heard the rule that many RVs can only maintain a temperature about 10 degrees cooler than the outside air. While every RV is different, that hasn’t been our experience.

We’ve camped in temperatures ranging from the 90s into the low 100s and have generally been able to keep our RV in the low 80s.

Factors like insulation, window placement, shade, air conditioner size, and outside temperatures can all impact how well your RV stays cool.

Since every RV and every dog is different, we also recommend following the AKC’s general hot weather safety tips for dogs when temperatures start climbing.

Always Leave Plenty of Water

We make sure Coco always has access to plenty of fresh water, whether we’re in the RV with her or leaving for a few hours.

It is also important to know the signs of heat stress in dogs if you plan to travel during hot weather.

It sounds simple, but staying hydrated becomes even more important during hot weather.

The goal isn’t to create a perfectly cool environment. It’s to keep your dog comfortable and avoid situations where the temperature inside the RV starts climbing faster than you realize.

Have a Plan for Power Outages

Even if your RV does a great job staying cool, every system has a breaking point. That is why we believe every RV pet owner should have a plan for what happens if the power goes out.

Use a Temperature Monitor You Can Trust

Our favorite RV pet safety tool is our Necto temperature monitor.

We have been using it for over a year, and it has alerted us to multiple power outages while traveling.

For us, that is the difference between hoping everything is okay and actually knowing what is happening inside the RV.

Protect Your RV’s Electrical System

We also use a Power Watchdog surge protector to help protect our RV from power issues at campgrounds.

Most of the time, it can automatically stop and restore power if it detects a problem. However, there have been situations where it needed to be manually reset before power could be restored.

That is one of the reasons we never assume everything will simply work itself out while we’re away.

Have a Backup Plan

Technology is great, but having a backup plan is just as important.

One of the things that gives us the most peace of mind is having people we can call if something happens while we’re away from the RV. Depending on where we’re staying, that might be a campground employee, a trusted neighbor, or a friend camping nearby.

We also know that Coco always has access to her doggy door and side patio… yes, I know that isn’t a standard RV feature but it has been amazing for us.

While that is not a replacement for air conditioning, it does provide another layer of protection if conditions inside the RV become uncomfortable.

The goal is not to prepare for every possible disaster. It is simply to have a plan before you need one.

Keeping Your Dog Cool Starts Before You Leave

Most of the things we do to keep Coco cool happen before we ever walk out the door.

We close the blinds, make sure she has plenty of water, set the air conditioners to maintain a comfortable temperature, and verify that our temperature monitor is working properly. We also take a quick look at the weather forecast and think about how the day’s temperatures might impact the RV.

None of these steps take very long, but together they help us feel much more confident leaving Coco in the RV for a few hours.

The reality is that there is no way to eliminate every risk. But with a little planning and the right tools, it is absolutely possible to keep your dog safe and comfortable while traveling.
