Hey! I have a new, never used (with the tag attached) dog carrier for $40. It's blue with white polka dots on it, and some beige as well. It's very spacious but I don't know the dimensions of it. I can measure it if you are interested. Very sturdy and safe. Inside is the harness attachment so your baby doesn't jump out. It also comes with two spacious pockets and I believe one is to put your water bottle, etc in. While it's not in use it can flatten out by unzipping and when you want to use it you zip it back up, all around. It also comes with a handle on top if you don't want to use the long straps. I believe 2 tiny ones can fit in it, or one small dog. I haven't placed any of mine in it but I have 2 babies, one 5 pounder, one 8-9 pounder, so if you need me to take a pic with them next to it or in it I can. I bought this recently but already have a few carriers and realize I don't need it. Any ques. feel free to ask!
