The ride home is the first car trip and it sets the tone. A dog that rides restrained from day one never learns to roam the back seat.
Restraint
A crash-tested harness clipped to the seat belt, or a crate strapped down in the cargo area. Anything that only clips to a collar is a hazard, not a restraint.
Motion sickness
Common in puppies and usually outgrown. Skip food for two hours before a drive, crack a window, and keep early trips short and boring.
Stops
Every two hours for water and a leashed potty break. Never let a puppy out of the car off leash, even in a quiet lot.
