How to Safely Secure Your Dog in the Car (By Size)
To safely secure your dog in the car, use a booster seat with a tether for small dogs, a secured harness or car seat for medium dogs, and a back-seat hammock or contained cargo area for large dogs. An unrestrained dog is a real danger in a sudden stop — to themselves, to you, and to other passengers. The right restraint depends on your dog's size.
Small dogs (up to 25 lbs)
A raised booster car seat lets small dogs see out the window (which reduces anxiety and car sickness) while a built-in tether clips to their harness to keep them in place.
Small to medium dogs (up to 40 lbs)
A larger booster seat for medium dogs offers the same secure, elevated design with more room. Always connect the tether to a body harness — never to a collar.
Medium to large dogs (up to 100 lbs)
For bigger dogs, a structured waterproof car seat contains them comfortably, while a 600D hammock seat cover protects your upholstery and stops dogs falling into the footwell.
Cargo and boot travel
For SUVs and estates, a waterproof trunk liner creates a clean, secure space in the cargo area, ideally paired with a barrier.
Frequently asked questions
Is it illegal to drive with an unrestrained dog?
In many regions an unrestrained pet can lead to fines or distracted-driving penalties. Even where it's legal, restraint is far safer.
Should I clip the tether to a collar or harness?
Always to a padded harness. Clipping to a collar risks serious neck injury in a sudden stop.
Where is the safest place for a dog in a car?
The back seat or cargo area, secured. Never let a dog ride in the front with an active airbag.
