Frequently Asked Questions

Is it a legal requirement to restrain a dog in a car in the UK?
Highway Code Rule 57 requires that animals are suitably restrained during car travel.
While there is no specific “dog seatbelt law,” failure to restrain a dog can lead to prosecution under careless or dangerous driving laws, with fines of up to £5,000.
Which is safer: a harness or a crate?
Crash-tested crates generally provide the highest level of protection in a collision, as they fully contain the dog and absorb impact forces.
Crash-tested harnesses offer good protection for rear-seat travel. The most suitable choice depends on your vehicle type, dog size, and journey frequency.
Can I let my dog ride in the front seat?
While not explicitly prohibited, the front passenger seat is generally considered the least safe position for a dog.
Airbag deployment can injure or kill a dog in a collision. If a dog must ride in the front, the passenger airbag should be deactivated and a crash-tested harness used.
Do I need a dog guard if I have a crate?
If your dog travels in a properly secured crate, a boot guard is not strictly necessary. However, many owners use both for added peace of mind, particularly if the crate is not crash-tested.
