Do you use a seatbelt harness when driving with your dog?

If my first two dogs weren't in their crates when travelling - they were either in harnesses or at the very least their leash handles (flat leash, never a flexi for his purpose) were run through fastened seatbelts.

It was recommended by all the trainers I've worked with, as well as the vet clinic. Also, I've had a couple of friends whose dogs jumped out open windows while they were driving.

Working in insurance, I've had to talk to people whose dogs were killed when they ran into traffic after their car was in an accident. Hard to rationalize not making sure my dogs were safe. Less than a minute of effort to protect them. I can do it.

all of the crates and soft carriers I've owned have had attachments for leashes inside. Haven't used them - but they were there (I could never figure that out).

are the leashes supposed to connect to the seatbelt? I was told that (according to the drivers ed) carriers are not safe for pet transport.
