Review on Petsfit Expandable Cat and Dog Carrier: Airline Approved, Soft-Sided, Washable, 🐾 Portable Pet Travel Carrier with Removable Soft Plush Mat, Pockets and Safety Zippers by Lisa Rice

We took our two Havana dogs, 15 and 17 pounds, on a flight to Alaska in these tote bags. They were easy to carry with dogs, like a duffel bag. Most people didn't even realize they had dogs inside them. The expandable side was crucial for the comfort of the dogs. If you are lucky enough to open the seat next to you in a 2X2 vehicle, there is no bulkhead under the seats. So both straps fit perfectly under the seat even when the side is folded out. If you don't have space, the straps only fit with the extender closed. Even when closed, the dogs seemed comfortable, but they were warm because there isn't that much ventilation. When the expander is closed, only the front and top are ventilated. The bag is convenient for storing treats, leashes and other things that will be at hand during the flight.
