Is there a good quality harness that doubles up as a car and walking harness? Dpup is 9 weeks old and has taken really well to his cliksafe car harness. As he will be able to go out for walks in a couple of weeks we would like to buy a harness that could be used in both situations. I was going to buy a Perfect fit harness, but now see that it can't be used in the car. I don't want to be swapping from one harness to another and we can't crate him in the car as the boot is too small.
