When traveling with a dog, ensure you have an ample supply of their regular food and treats to avoid dietary upset. Changes in diet can cause stress or digestive issues. If traveling by plane, consider shipping food to your destination in advance to avoid shortages. Always check with accommodations about receiving packages. For immediate needs, carry a portion of food in your carry-on. Also, research local pet stores at your destination that carry familiar brands. Maintaining a consistent diet is vital to keeping your dog comfortable and healthy during travel.
