Pet Carrier for Small Dogs, Medium & Large Cats | Airline Approved Bag Under Seat, Expandable, Soft Sided | Cat, Dog, Kittens, Puppies Carriers Up to 16lbs with Free Travel Bowl by GloBal Pet

This is a great bag for small dogs or cats! I got it for my little rambunctious 5lb Yorkie, and he has never been happier in a bag before! I think he and I both love the fact that you can unzip it from one of the sides to have it open up sooo much more, Giving him a lot of extra space in there! It's definitely bigger than I had imagined, it could definitely fit a bigger dog, but nothing much bigger than a pug I'd say.
