Hello, We are due to pick up our Cocker Spaniel pup in 6 weeks time. I've been searching for the best way to transport a puppy in a car? Initially on her first journey home I will be sitting in the back of the car with her, but I am struggling to find what is best for future journeys? I've seen crates, dog guards, soft carriers/cradles and harnesses that attach to the seatbelt. Any suggestions on travelling as a pup and when she is bigger? Thanks.
