My 8 month old Jack Russel puppy, suffers from car sickness, has done from about 3 months old.

We only need to travel up to 1 hour, and she starts, usually twice, poor thing.

Could anyone tell me if this is inbred in JR's.

My last little JR/Dacshound. had the same problem.
She was a rescue dog,and we were only privalleged to have her in our life for 3yrs, before we lost her in march with a brain haemmorhage. this we put down to the problem of car sickness with her too.

Is this a coincidence, or is it inherant?
