Please get your adorable pupper a seatbelt!!! And make sure you get a good and properly tested one as most suck. Remember, any unsecured object (including bodies and organic matter) can become lethal projectiles in an accident.
I’m not sure if it’s properly tested but we have a rear seat system for him, he was just such a good boy I let him sit in the front for a little bit on some back roads.
True story, every time I see a golden retriever when driving (by myself), I say "WHAT A GOOD BOY" out loud habitually. Only goldens, and sometimes labs if they look extra behaved.
Maybe that's cringe to some, but I adore these dogs.
