I bought this car seat in anticipation of making several long road trips this fall. I wanted something comfortable and safe for my dear dog Benny, a 3-year old miniature poodle.
Hubby and I took Benny out for several one-hour trial runs over the past few weekends and Benny seems to love this seat. First of all, it boosts him up high enough so that he can comfortably look out the window (while still being safely tethered to the seat). Second, having ordered the larger model, he can stretch out and sit or sleep without being cramped. And third, and most important, is that while wearing his comfortable, stretchy Puppia harness, we can tether him to the seat belt, which secures the car seat just like a child's car seat. This gives Benny enough "give" to move from side to side in the seat, but in the event of slamming on the brakes, he'll stay secured and not end up a hood ornament (hopefully lol).
Be warned - this model is BIG. I have it in the back seat (2nd row) of my SUV and it takes up half the seat. Instead of room for 3 people, there's now room for only 1. No bother. He's my only "kid".
