I like to take the dogs I housesit for out in my car (or car loaned by houseowners when travelling) to explore different areas, nice for the dogs and me. Sometimes the owner has had restraints for the dogs when travelling, usually attached to the seat belt holder. Other times they haven’t so I’ve travelled with the dog(s) in the boot, removing the parcel shelf. I’ve had no problems thus far. However when the wife of one of my cousins saw a pic I’d posted on Facebook of two dogs in the boot she brought to my attention that I could be fined if I had an accident and the dogs were found to be unrestrained.
I attach a link with further information:
Should you, as owners, be required to provide restraints or a cage for sitters to use for the dogs?
