“The barrier is advertised as a pet barrier however I've installed it in my 2019 Ford Everest and my Australian shepherd (similar to a Border Collie, approx 22kg so not a small dog) can still squeeze through the gap at the side of the barrier. Given my 22kg dog can fit through, there would be a huge number of dogs or cats that could fit also through that gap also. I'll have to now modify it to make it work as advertised. Would only recommend if you had a large dog”
