One tip that easily cuts down on dog hair accumulating in your vehicle is to give your pet a good brushing before taking a ride. For very hairy dogs, you might need a special product like the FURminator to really tackle the hair. Consider getting a car seat cover made for animals. Once the ride is over, remove their seat with the animal's hair, and give it a wash.
Using a pet crate for the ride or putting a harness on your fur baby can keep them and their hair contained. These products also keep your pet safer during the ride around Honolulu or wherever you travel.
