German Shepherd dog

Depends on the size of your 11 month old GSD. I would say it is too small if the dog is over 55 pounds.

It would be a bit small.

I bought the larger 48" this year, it will fit the back of my Cherokee, can't say about other vehicles .     It is the steel folding type.  My largest male dog is comfortable in it and sleeps there when a bitch is in heat.   42" would probably do for you, I don't know for sure what you need. 

For use in the home I have a very large crate, but the only crate that would fit in my car is a 36. My Male lies comfortably in it and I feel that it is fine for a couple of hours for training and the commute. I wouldnt feel good about using it in the home for or when he has to be in there for an extended time, but it works fine for me for short term use while training and driving.

I would add that mine seemed more comfortable in the smaller size when traveling, less sliding around.  

A 36" is PLENTY big!!  My crates in the car are 24x36 and both dogs can stretch out, and sit up, they are a bit slouched, well Jager is but they have MORE than enough room!  Most custom crates for cars are smaller, look at the crates built for Ford Explorer and those are only 21" wide.  Both of my dogs tend to jump into the same crate for some crazy reason, they both fit in there, it's tight but they manage to get in there!!!

I think the width is very important as well as the lenght, but I know a lot of people who also travel with their dogs in 400 crates, and that works fine as well.

You should be just fine with the 36" so long as it's not only 18" wide!  Jager is about 84 pounds and he has plenty of room to grow in there still!!!

You should really consider putting her in a harness while you are driving if you are not, a minor accident can send her through the windshield, bad bad news!  We have a lady at our club with a little Eclipse, I keep telling her she needs to get a dog car, her dog barely fits in there anymore!  There is a lady at the Monterey Bay club who drives a BMW Z4 and she had the passenger seat removed so her dog can ride along with her (she does seatbelt him in) so whatever works for ya!

I have the SUV crates in the car now, and they are 21 inches wide.  My male gained a 10 inches in head room and 6 inches in length from the 36 inch one.  Even with 21 inches wide he can turn around no problem, and he's a pretty long fellow. 

you don't have too many questions kool!  And your questions are always good questions, so ask away!

Jut checked, these are 24x36x27 so the 400's that I have used in the past, the plastic ones must be smaller somehow, bc they fit side by side and these do not at all

One opens sideways and Jager gets in from the back of the car, and the other opens from the short side and I let Sasha in from the passenger door.
