For an interstate trip, start with the state you’re going to. USDA APHIS directs pet owners to the destination state or territory’s requirements. A certificate of veterinary inspection, vaccination or another condition may depend on the destination. That matters for routine car trips as well as bigger moves. Give yourself time to get an appointment if the state requires veterinary paperwork. USDA APHIS state-to-state travel guidance

Keep three checks separate

First, open the state animal-health authority’s instructions for your dog and trip. If you’re staying in more than one state or returning after an extended stay, check the relevant requirements for those legs too. Second, check the transport company’s own conditions if you’re flying or using another operator. Third, confirm that overnight lodging accepts your dog under the terms of your actual booking. Acceptance on one of these checks doesn’t answer the other two.

Keep dated notes of the agencies you checked and save copies of any records required to travel. If a state form looks like something you need, share the official page with your veterinary practice before booking. This is a domestic trip checklist. A journey that crosses the Canadian or Mexican border also needs the separate international rules, including the route back to the US.
