Brands like Kurgo make great travel gear for dogs that not only protects your dog, but protects your vehicle. The harness that buckles into a safety belt buckle is great, because it allows the dog to still see out the window with the wind in its face but prevents their head from the leaving the car. It also helps provide stability for the dog on curvy roads or stop and go traffic. I also like the hammocks or back seat barrier, because it prevents the dog from getting into your space and distracting you from driving. These companies even provide travel aids for aging dogs that may have joint problems, such as stairs to assist them into the car and padded beds.

You may also be considering traveling by plane with your pet. More airlines are becoming more pet friendly, but there are still concerns. Small pets, under 20lbs, can travel in the main cabin with you. Larger pets are stowed away as cargo. If your pet is going to be packed with the cargo, please read these tips from the FAA to ensure your pet has a safe flight and consult your vet regarding health concerns. There are specific airlines just for shipping pets that are more accommodating. However, these airlines charge high prices, and you cannot accompany your pet.
