With proper planning: 2-3 hours maximum between breaks. Dogs need bathroom breaks, water, and exercise. During breaks, limit car time to brief stops (under 10 minutes) unless the temperature is ideal (60-75°F) and you're present with the car running and climate control on. Never leave dogs unattended in vehicles even with windows cracked, temperatures can become dangerous within minutes. Plan your route with pet-friendly stops every 2-3 hours.

For motion sickness: 1) Withhold food for 3-4 hours before travel (water is okay), 2) Keep the car cool and well-ventilated, 3) Use window shades to reduce visual stimulation, 4) Offer small amounts of water frequently, 5) Consult your vet about motion sickness medication (never give human medication), 6) Try natural remedies like ginger treats (check with vet first), 7) Practice short trips to build tolerance. If vomiting occurs, stop at next safe location, clean up, offer small amounts of water, and resume when dog seems comfortable.

For entertainment: 1) Bring favorite toys (quiet ones for hotels), 2) Use puzzle feeders or treat-dispensing toys during stops, 3) Play calming music or audiobooks, 4) Offer safe chew items (supervised), 5) Practice simple training during breaks, 6) Provide window access (with safety restraint), 7) Rotate toys to maintain interest.
