This booster seat is best suited for pet owners who want a comfortable, safe, and easy-to-clean option for smaller medium-sized dogs, especially for use in both front and rear car seats.

The Snoozer Lookout II dog car seat is designed for medium-sized dogs up to 34 pounds, providing a raised seat 6 inches off the car floor to give your dog a better view and help reduce car sickness and anxiety.

This car seat is specifically sized for dogs under 34 lbs, so larger breeds won’t fit comfortably. While the foam and fabric are durable, the seat’s elevated design requires a back seat with enough space, which might be limiting in smaller cars.

Comfort is a strong point here, thanks to the plush microsuede cover, removable pillow for extra height, and high-density foam that absorbs shocks to ensure smoother rides.

Safety is addressed with raised sidewalls and a harness clip that secures your dog and minimizes driving distractions.

Durability is supported by high-quality polyester materials and a removable, machine-washable cover that’s stain- and water-resistant. Weighing just 9 pounds, the seat is light enough to move in and out of the car easily.

The weight limit restricts this seat to smaller medium dogs, so larger breeds won’t fit comfortably. Also, while it fits snugly in a single car seat, it may not suit larger vehicles or dogs that prefer more space. For dog owners seeking a comfortable, safe, and easy-to-clean car seat for their small to medium pets, the Snoozer Lookout II is a solid choice. Those with bigger dogs or needing more heavy-duty options might want to consider other seats.
