​ The Cool Dog Car Ventilation Tailgate Lock. This amazing product is designed to allow greater airflow and ventilation by keeping the tailgate open but locked. An open window on a warm day is not good enough to keep a vehicle cool enough to leave a dog. The Cool Dog Car Ventilation Tailgate Lock allows more ventilation into your vehicle  than only leaving windows open. It works by fixing the rear tailgate or door in a half-open position and with a front window open just a small amount, it will allow air to flow and circulate through your vehicle helping to keep your dog cool. Enhances Ventilation: Allows greater airflow and ventilation by keeping the tailgate partially open but securely locked. Effective Cooling: Provides more efficient cooling than simply leaving windows open on warm days, ensuring a comfortable environment for your dog. Security Feature: Deters potential intruders, offering peace of mind that your vehicle and pet are protected. Easy Installation: Can be quickly fitted and removed with minimal effort, allowing for convenient use whenever needed. Universal Fit: Compatible with most Estate Cars, Hatchbacks, Vans, or 4 Wheel Drive vehicles with a rear door, offering versatility for different vehicle types.
