road trip packing list for dogs (from our trip to Hua Hin)

we did 4 hours drive to hua hin with maya and cheddar last month and i forgot half the stuff so here is what i'd pack next time. towels. lots of them, old ones, the back seat gets wet and you dont want to clean it later. a puppy pad or two in case of car sickness, cheddar throws up every time. water from home, not bottled from the shop, because the change in water can give tummy upset. also a seatbelt harness for each dog, the clip for the seat is not enough. and a baggie with poop bags, obviously lol. mayas favorite toy went missing on the hwy, dont be like me. label stuff and bring the sprays for when the car definately smells.
