Firstly don't sympathise, if you show any stress or worry she will pick up on it.
I am an Elk hound owner and until last year did not have a car of my own as I don't drive due to visual disability.
All mine learnt to travel well, and very few of the puppies I bred had travel issues, but one or two did.
Unfortunately one such bad traveller had to travel by car abroad!!! she was really sick by the time they got to Dover, but she is now 12 years old and travels fine, and no it didn't take that long.
The best thing for reducing travel sickness is to restrict movement.
I had to start my own pups on the bus, as they only got to travel in Friends cars,a nd I certainly didn't want them being sick or being a problem for other people.
I also found that having a pup by my feet in the well of the car in front (short local journeys)meant they were reassured by my presence, and restricted in movement, and in a part of the car that moved around the least.
Often the back of the car moves around the most especially in 4 x 4's.
My current 14 months old obviously found travel a bit nauseating, but having already gotten used to being still at my feet, adopted the keeping still in her place to minimise this.
she still feels a little queasy I can tell, but loves travel because she likes to be part of everything and going away, and to shows (certainly hasn't stopped her doing well).
If we are travelling with all five dogs with the rear foot-well full of our gear then she can be tethered on the back seat with my eldest, with the other three in the back.
The middle of the car moves about the least, so if you ca secure her crate there all the better for now.
The key thing is that all journeys should end in a pleasant outcome, and sadly the first ones often don't.
Also I suggest you join our UK Elkhound group on the net, PM me for the site address, and you can share and ask other elkie owners all things elkhound.
She will grow out of it, as Elkhounds are very adaptable and make great travelling companions. Mine are real gypsies.
