Skip a meal on travel days
No matter how accommodating you are to your pet, some anxiety on their part is inevitable. Bernal says a common symptom of this is stress diarrhea—which is the last thing pet owners want to deal with on a long car or plane ride.
Even if your pet doesn’t seem stressed before the trip, plain old motion sickness can upset your animal’s stomach rather quickly. Bernal recommends feeding them less than you usually would prior to traveling to avoid future accidents: “If you have a pet you know has those sensitivities, I would keep their tummy empty.
It will be good for the pet and it will be nicer for everyone in the car too.” That doesn’t mean you should starve your pet if they’re begging for food; just skip the last meal you would normally feed them before beginning your journey.
