The main reason to use a dog car seat is to keep your dog restrained.
Many dogs jump around the car which can be very distracting to the driver and dangerous for both you and your dog.
Dogs should never ride in the front seat in case the airbag deploys which could cause death
or serious injury.
Your dog will be able to see out the window.
Dogs love to see what's going on.
They are less likely to slide around, this can also help with motion sickness.
The seat is like a bed so your dog feels more secure and can even lie down and have a
sleep on longer trips.
