We like the 4Knines SUV Cargo Liner due to its effectiveness and ease of installation. Simply attach the headrests on the back or front seat of your vehicle to give your dog some breathing room. It has a few minor flaws (Cover size issues) that can be corrected over time. Still, it's a durable and appealing cargo liner that will make your trips with your dog more enjoyable.
Dogs bark at people because in many cases, they are not accustomed to being around strangers other than their families. Dogs also have keen observation skills, meaning that they can read human body language well enough to sense suspicion or threat based on a person’s actions and bark in response.
