From IMDB:

Two former Army Rangers are paired against their will on the road trip of a lifetime. Army Ranger Briggs (Channing Tatum) and Lulu (a Belgian Malinois dog) buckle into a 1984 Ford Bronco and race down the Pacific Coast in hopes of making it to a fellow soldier’s funeral on time. Along the way, they’ll drive each other completely crazy, break a small handful of laws, narrowly evade death, and learn to let down their guards in order to have a fighting chance of finding happiness.

From Amazon Prime you can stream this 1 hour 41 minute comedy-drama.

While not exactly fit for children, this dog story has moments of fun, sadness, and eventually redemption.  Definitely a feel-good film.
