I have two designer bags and mine and my puppy's fave is the non-designer one we have
. I have a Juicy Couture one that is super cute but it's really floppy and folds in on her. I also have a Kathy Vanzland (sp) bag but one side of it sinks in and the pockets are so small that they are pretty much useless. The bag that is my favorite is Ful brand. It's not that cute but its sturdy and has enough storage for everything you will need when you are on the go with your puppy. HTH, good luck!
