My new puppy wasn't thrilled about riding - but since using the pet carrier, she's become much more comfortable.  I had another pet who passed away this past January.  She never rode in a pet carrier.  We had a wreck and thankfully she received only minor injuries....but now, I feel that my puppy will be much safer if we ever have another accident.  Can't say enough good about this item!  If you're thinking about buying one - do it!
