We adopted our dog from The Cavalier Rescue. Finnegan was located in Missouri and we live in California. We flew to Missouri and rented a car to drive Finnegan home. A good comfortable car seat was essential for our five day journey home. Snoozer made sure the car seat was delivered to Finnegan’s foster home in time for out trip. The car seat must have been comfortable because when we would stop for a break he couldn’t wait to get back into his car seat. We chose the large size even though the smaller size would have worked because we wanted Finnegan to have plenty of room to spread out on our long journey home. Now at home Finnegan can share his car seat with a fur sibling and there is plenty of room. And added bonus is this car seat is much easier to install and remove from the car then the other car seats we have. I highly recommend this car seat.
