    I use my Vent locks all the time. They work really well and it’s so nice to be able to leave my van locked and still allow significant air flow. I have the longest Ventlock and also the 6″ length so that I have a choice depending on the situation. Of course, all necessary precautions must still be used, i.e. parking only in the shade and only leaving dogs unattended in a car on cool days, etc. I highly recommend these for people who travel with dogs.

    I learned about these locks about 10 years ago when I was visiting a dog event. Over the years I’ve had various makes and designs of them however this one seems to be the highest quality and well built one so far.

    Ideal for short time leaving dogs in car, allows cool air to flow through whilst car is still locked
