Wear it as a backpack or carry by handle. There is plenty of room for Sonny to lay down. Make sure you keep the zippers are closed on the top. I closed the one side where zippers were at the side, and he was able to open it. Glad this happened while I was still in the house!
The carrier is perfect for when you and your pet have to go to the vet or to keep secured while in a vehicle. The pocket is good for leashes. I don't suggest keeping treats in the pockets. Excellent carrier.
