The breeder I got Annie from had a puppy carrier from Build a Bear. She used it to transport puppies to the vet. It was simple and cute as can be. Perfect for little puppies who seem to drown in the bigger bags for a few months. They don't sell the same one but do have almost the same with wheels added $16. (

I wish they would put dimensions on their website because there are several things I would order if I was more sure on size. I think I will wait to go to a Build-A-Bear in person. We don't have one here but there is one about an hour away.
