I don't know if they have something similar in Belfast, but my sister got this for her dog and when I was driving him somewhere on my own I used it - it works as a backpack, rolling pet carrier, or carseat:

She doesn't drive because she lives in the city so she's hinted that she might be giving it to me for Lucky so I can use it in the car as a car seat. ...
