I'm getting ready to order a crate in the next couple weeks for the Frenchie I will be getting probably end of August or first of September. She is full grown and weighs about 23 pounds. I was thinking the 30" long by 20" wide would work, but now I'm not sure. I wonder if I need the 36" X 24"? She will be in it at night until she settles in and hopefully will sleep with me. Other than that she will mostly just be in it for short periods if I have to run to the store or whatever. I don't mind buying the bigger one, but the thing is that I will be taking it on vacation with us and our trunk is kind of small and I want to make sure everything will fit in there. It's already kind of packed without a dog, now we are adding a dog crate and stroller to the trunk so I don't want to buy one any bigger than I have to. What do you guys think? I mean, she doesn't have to be able to play a game of fetch in there, just be able to comfortably turn around, stand up, and sleep.
