Who Needs Dog Car Harnesses?

Dog car seat harnesses are a must for any pet owner. If you own a car and care for a pet, you’ll likely want to take them out for a drive. Ensuring your pup’s safety in the car isn’t just a good idea; it’s the law.

Your Dog’s Safety

Dog car harnesses are just as essential for safety as seatbelts are to you and me.

You will already know of the dangers that can occur to us if we don’t wear seatbelts, and these dangers are just as real to dogs. No matter where you place your dog in the car, they can easily fall into something or be thrown across the vehicle if you need to stop suddenly. 

If, for example, you need to swerve to avoid something, then your dog could again just as easily fall or hit itself against something. You don’t need to be in a car accident for harm to come their way.

Even things that could seem minor to us could significantly harm a dog who is not attached correctly in a car. 

Therefore, you really shouldn’t take any chances – a no pull dog harness on its own may not be enough, so look into specialist dog car harness brands.

Your Safety

Dog harnesses do far more than just protect the dog; they are also essential for the safety of everyone in the car. 

Even the calmest of dogs tend to move about during car journeys, especially longer ones. During the trips, dogs do get bored and tend to move about the car. More excitable dogs will happily jump over seats and do their best to reach their master, which could be you, the driver. It is very easy to become distracted and lose focus on what is happening on the road in those instances. Obviously, this can spell disaster for anyone in the vehicle! 

Moreover, as previously stated, in emergencies where hard braking or swerving is required, a dog can be thrown all about the car and into someone.

What The Law Says

By law, animals must be suitably restrained during car rides for both you and your dog’s safety and ensure that they are not the cause of distractions for the driver. 

You have the option of using a cage, a dog guard in the boot, or pet carriers for smaller dogs. 

However, pet carriers are only suitable for very small dogs. Moreover, harnesses are far cheaper and easier to use than dog guards and dog cages. They can also be used in any kind of car.

How Does a Car Harness Work?

A car harness works by keeping a dog in a sat-up position and taking its own seat during road journeys. 

Simply command your dog to sit on the seat while they use the car seat belt system to tie them in place. We say ‘simply’ – fussy pups may vary!

You can either use a tether to plug the harness into the seatbelt buckle directly, or you can put the seat belt through the harness, then tie the seat belt as you usually would. 

Car seat harnesses are the best assets to ensure car safety for dogs and their owners! 

What to Look For When Choosing a Car Harness for Your Dog

As car-fitted harnesses are built to keep your dog safe during road journeys, there are a few things that you can expect from the quality and ease of use this equipment grants you.

As they are often used as walking harnesses, you should consider their efficiency in both activities. 

Crash Testing

The first thing that you will want to ensure is that the harness has been crash tested. You would not want to sit in a car with unsure seatbelts, and you should not want that for your dog either! In order to keep your furry friend safe, it is your duty to ensure that their equipment is reliable. You never know when you might need it! 

A good car harness will be noted as being crash-tested on the packaging, but it is always wise to check! 


Ensuring pet safety during car rides means having the right equipment. Even the best harness will be rendered useless if it is not the right size! 

You will need a harness that is not so big that your dog can easily wriggle out of it during the drive. It will also need to be tight enough not to allow your dog to move too far forwards or to the side in the event of an accident. 

However, it will also need to be large enough to not squeeze and suffocate your dog during the journey.


Along with the size of the harness itself, you will also need a fully adjustable one. No matter your dog’s breed, it will have specific measurements that are not suitable for all kinds of dog gear. With that in mind, you will need a car harness for dogs that can adapt to your dog’s body, not the other way around. 

To ensure that it is not too tight, you should be able to place three fingers between the harness and the dog’s skin. It should also be tight enough for walk and car safety!

Easy to Put on and Take Off

Whether you take your dog on car rides often or not, you will need a good car harness that is easy to get on and off.

You will not want to waste time having to play about with the different straps, and your dog is more likely to become bored and agitated if they have to wait for too long. 

That is why having something that is easy to administer, with solid buckles and multiple openings, is always a good idea! 

It also means that it will be easier to get your dog out of the car in the event of an accident.

Does it Come With a Seat Belt Restraint?

Many car harnesses today automatically come with a seat belt restraint, and for the most part, it is better to have them. 

Depending on how the harness has been designed, it may be more comfortable for the dog to have a seat belt restraint, as opposed to putting a seat belt through the harness. 

The best dog seatbelts like the ones from Kurgo and Mighty Paw need to be strong enough to handle your dog’s weight at all times, especially if their weight is pushed away from it. 

You will also need to make sure that the buckle is suitable for the seats in your car! 

5 Tips for travelling Safely With Your Pooch

Always use a Harness.

Using a dog harness is the best way to ensure your dog’s safety in the car. You do also have the option of using a dog guard or a cage, but remember that you will need the space, and the dog is more likely to be thrown about in an accident than they would be with a harness.

Use the Back Seat

Where should your dog sit? Having them ride in the front can be very dangerous for you and your dog. For everyone’s safety, keep them on the rear passenger seat. They are far more likely to distract you in the front seat, and the airbag inflating should you have a bump could be fatal.

Stop Frequently

Dogs need frequent toilet breaks, and making them wait is dangerous for their health. It also runs a high risk of causing an accident in the car! It will also help them to stretch their legs, which is especially important for bigger dogs.

NEVER Leave Your Dog Alone in your Car

They can become dehydrated, or if the windows are left closed, quickly suffocate. They can also get scared, hurt themselves and damage the vehicle. If you need to stop, try bringing them with you, or leaving them with someone you trust.

Keep Your Dog’s head Inside the Car.

Even though it may seem funny and cute, it is actually very dangerous to let a dog stick their head out of the car window. They could easily hit something, something could fly into their eyes, permanently harming them they can even jump out.

Can I use a walking harness in the car?

Some walking harnesses do work in cars and have specific attachments for the car seat belt. However, car harnesses are specifically designed to handle the possible force of accidents and with the right attachments for the safety seat belt.

Which is the best dog seat belt UK?

The best seat belt is one that can attach to your vehicle precisely, which not all dog seat belts can! It should be made of strong material and should be easy to undo if necessary. You do not want a seat belt that could easily get stuck, especially if you need to get your dog out quickly.

Can my dog travel in the front seat?

Yes, but it is not safe to have a dog riding in the car’s front seat as the airbag can do serious damage should you have a bump; the back seat is a safer choice.

Can you use a Kurgo Tru Fit harness in a car?

Yes, there is a Kurgo Tru Fit dog harness that has been specifically made for the car. It even comes with a seat belt attachment to ensure that your dog is secure. However, always make sure you specifically have a dog car harness in the range!
