Why Does My Dog Drool in The Car [6 Reasons with 7 Solutions]

A dog’s drool is not a new thing.

Similarly, this should not be a common occurrence.

It is also a matter of some concern.

Various situations can affect your dog to drool while in the car. Either they’re car sick or incredibly pleased when a dog starts drooling in the car. When they are overwhelmed by extreme emotions, your pet can drool excessively. Again, heatstroke and thirstiness can be other causes of drooling.

You’ve come to the correct place if you’re fed up with cleaning it up or concerned about their health. 

To know more, let’s move into the next portion!

Reasons your Pet Drool

Your dog may drool in the car for different reasons. Some of them are described below.

Due to Motion Sickness or Car Sickness

Your dog may pee on his bed, which is not rare. You’ll see your dog drooling and licking his lips a lot. He may also scream, whimper or refuse to move.

Dogs of all ages and breeds can suffer from these.

All these can happen from motion sickness as well. 

Dogs who have had poor experiences may establish a dread of riding in the car as a result of this.

Additionally, this adds a neurological component to the physical pain that your pet experiences when traveling in the car. 

Tooth Decay or Mouth Infectious Disease

Drooling is beneficial for a dog’s teeth in most cases. But excessive drooling is not. Gingivitis and periodontal disease may be present. 

The gums will become swollen and irritated as a result of this condition. Without treatment, teeth will loosen and fall out, or they may have cracks in their teeth. 

This excessive drooling can be seen as an early warning indication that anything is wrong with your dog’s dental health. It is also possible for drooling to occur as a result of oral, gum injury, or chattering of their teeth.

Acute Heat Exhaustion 

If you’re not running the air conditioning in your car, remember that your dog wears a “fur” coat all year and can’t cool off as much as you can.

On a scorching summer day, what we consider cozy or even freezing for ourselves may not be so for your dog. 

Brachycephalic dogs, such as Boston Terriers, Pugs, and Boxers, are more susceptible to heatstroke because they have difficulty cooling down their system through panting. This can be a reason for drooling.

Anxiety and Excitement

You may notice your dog drooling excessively in the car if you take him to the vet for vaccines or other unpleasant procedures. Strong emotions could be the source of your dog’s excessive drooling. If they’re worried about driving, this can happen.

On the other hand, your dog may drool as a reaction to a car journey because he’s so happily excited about it. There may be moderate drugs available from your veterinarian to stop overwhelming emotions.


The drool of a thirsty dog is quite a lot. Because their body is telling them it needs more water. This could be the reason for your dog’s constant drooling.

Their heart rate and blood pressure rise. When this occurs, more water is required to maintain control. If they have a steady supply, it’s not a problem.

Other Probable Reasons

Before looking into other possibilities, ensure your dog hasn’t been infected with rabies. Foaming at the mouth is a rabies symptom, often accompanied by increased thirst and other behavioral abnormalities. 

A foreign substance lodged in your dog’s mouth or throat could generate excessive saliva. 

Drooling may be brought on by some medications, allergies, or poisoning. Drooling in dogs can be caused by various conditions, including genetic problems or abnormalities in the development of the mouth.

7 Solutions to Keep Your Dog from Drooling

These problems can be avoided with a few simple steps. You don’t have to buy anything specific to take advantage of this offer. Change your habits to control theirs. Let’s look at how you may avoid drooling in the automobile.

Driving While Hungry

Your dog shouldn’t travel right after feeding. After they’ve eaten, you should give them at least an hour of breathing room. 

Both meals and sweets have the potential to be harmful before a journey. Avoid giving fancy food like oatmeal to your dog just before a long trip. 

Make Frequent Stops

Don’t leave your dog in the car for long periods. They must be able to take a break. Motion sickness can be avoided by using this technique.

The Windows Should be Rolled Down

Fresh air and constant ventilation are essential. This avoids heatstroke, thirst, and anxiety and calms the nervous system. Your dog’s temper will subside.

Have Fun with it

Never treat a car ride as a form of discipline. Getting your dog into the car by yelling or shoving him is a bad start to the trip. As a substitute, reward them with praise and a favorite item.

Make a Lot of Trips in your Car

Make sure your dog is along for the ride every time you drive. Take them with you if possible. More time in the vehicle will make them feel at ease.

Make Adjustments for your Dog

Make sure your dog has plenty of space inside the car. Dogs are often too big for little cars. As a result, they may become anxious or stressed.

Movement and environment inside the car are essential; just like it’s important inside the house, dogs need a good environment.

Visit the Vet’s Office

An anti-motion sickness medication can be obtained from the veterinarian. This is an option if you’ve exhausted all other options.
