Our puppy absolutely hates her crate, poos in it every time and it has long since been abandoned. However, this leaves me in a bit of a quandry as to how we are supposed to safely transport her in the car. I looked at one of those dog car harnesses in the vets today but it looks like they have to be clicked into one of the seatbelts and we have 3 kids so there aren't any spare seatbelts if we are all out together. I did think about a dog guard to keep her in the boot but our boot is quite big so surely she'd fly around inside?
Are there any other dog-in-car options that I'm missing which anyone can please recommend?
