Whether or not your pup should be crated in the car is a personal decision and something that you and your dog will have to determine together. Generally speaking, having your pup in a crate can provide more security for both them and you as it keeps them in one spot. Additionally, many dogs are more comfortable when confined to a small, safe, and familiar space. On the other hand, if you have a larger vehicle with ample room for your pup to roam around safely during the ride, then they may prefer this option. Of course, they should be attached to a seat belt or harness. Ultimately, what's most important is that your pup feels safe and secure while on the road and that their needs are met with whatever option you decide to go with.
