Tip: road trip with dog, what i forget last time

We drive to Hua Hin last month with Fah and I forget half of things. Dog bowl yes. Towel yes. But I forget his poop bag and the car smell all weekend. So now I have list. First, water from home. Fah not drink the water from the hotel very well, so he get tummy upset 2 times. Bring big bottle, 2 liter is ok, can not carry more. Second, blanket that smell like home. The car seat is hot, and on the highway the aircon in back seat is not so cold. My husband put the old blanket on the seat and Fah sleep the whole way. Third, medicine for car sick, ask vet first. Not give human medicine, very very dangerous na ka. Fourth, wet tissue and garbage bag, many many. Also one extra leash because the first one always the one I lose at the rest stop. Last thing, do not let him sit on your lap while driving, very very dangerous. Use crate or seat belt harness. Fah hate the crate so we use harness, he is more happy. Ok that is all. Have a nice trip.
